They LAUGHED at her for 7 YEARS when she planted BAMBOO in the DAIRY PASTURE — until 1996…

The spring of 1989 was the loneliest I have ever known. After Vernon Lapp’s truck rumbled away, I knelt in the gravel with my son, Joel, and my daughter, Ruth. The evening air had turned sharp, smelling of wet earth and the sourness of silage from the barn. I pushed the last rhizome into the hole, exactly eight inches deep, exactly as Dr. Tanaka had instructed. I pressed the soil down with the flat of my palm, and I felt the cold seep through the fabric of my work dress and into my bones.

— Mom, Joel said. His voice was quiet, the way it had been since Owen left. We’re almost out of daylight.

— I know.

Ruth, who was nine years old and still laughed for all of us, held up a bucket of water with both hands. Her cheeks were flushed pink from the wind.

— Does this one get a name too?

— Yes, I said. What do you want to call it?

She squinted at the small mound of dirt where we had just planted the rhizome.

— Eliza.

— Then Eliza it is.

I wrote the name in my composition notebook that night, by the dim light of the kitchen lamp, next to a numbered map of the planting layout. The notebook was the same one my father, Jacob, had given me in 1972, the year I married Owen. I had recorded every cow I’d ever owned in it, every load of hay I’d ever cut, every birth and death and sale. Now it held the names of 235 bamboo plants that my daughter had christened.

The laughter began in earnest the next week. I heard it secondhand, carried to me by the way the neighbors averted their eyes at the feed mill, by the sudden hush when I walked into the diner on Route 23 in Blue Ball for a cup of coffee. I didn’t need to hear the words. I’d grown up in this community. I knew the shape of its silences.

On the first Sunday in May, I drove past the Weaverland Mennonite Church just as the service was letting out. I saw Calvin Stoltzfus, my late mother’s first cousin once removed, standing by the fence with two other men. They looked at my station wagon, then at each other, and I saw one of them—a man named Eli Fisher—shake his head slowly, the way you shake your head at a horse that has gone permanently lame.

I kept driving.

A week later, Calvin came to the farm. He pulled into the driveway in his black Plymouth, and I met him on the kitchen porch with a pot of coffee and two cups. He sat heavily, his knees giving the small crack of a man who had spent sixty-four years bending to milk cows.

— Matilda.

— Cousin Calvin.

— There is talk.

— I know there is.

He wrapped his thick, weathered fingers around the coffee cup and stared into it as if it held the answer to a question he didn’t know how to ask.

— People are saying that you have lost your way.

I didn’t answer right away. I looked past him, toward the north fence line where Joel and I had spent the last two weeks digging two hundred and thirty-five holes, one by one, with a borrowed post-hole digger.

— I have not lost my way, I said.

— People are saying that with Owen gone and the dairy under pressure, you are reaching for things that do not belong on a Lancaster County farm.

I set my cup down on the porch rail. The ceramic clinked against the wood.

— The thing that does not belong, cousin Calvin, is a milk price that has been falling for eight years, and a federal subsidy program that pays my neighbors to slaughter their cows, so that the price stays barely above the cost of production for the few of us who keep going. Bamboo is a forage. It is also a windbreak. It is also a herd shelter. It does belong on a Lancaster County farm, just not on any of theirs yet.

Calvin stared at me. He had been a careful farmer for forty years. He was not exactly opposed to my reasoning. He was simply not used to hearing reasoning of that kind from a forty-two-year-old Mennonite woman in a plain dress and white prayer covering.

— Tilda, will you let me ask one more question?

— Yes.

— Will you go back to church?

I felt the question like a hand pressing on an old bruise.

— I will go back to church when the sermons are about something other than how I should be raising my children differently.

He nodded. He finished his coffee. He drove home. He did not, in the next seven years, ever make another comment about the bamboo, although he did not stop the talk at the auction barn or the feed mill. And he did, on three separate occasions in 1992 and 1993, drop off a basket of his wife’s canned peaches with a folded note that said, “Only thinking of you and the children.”

The summer of 1989 was a slow summer. The bamboo shoots stayed under three feet. The leaves were small and pale. The neighbors who drove past on the township road saw skinny green stalks that didn’t look like much. What they didn’t see—what they couldn’t see—was the rhizome network spreading invisibly beneath the soil. Dr. Tanaka had explained this to me in the lobby of the conference center at Penn State, drawing diagrams on a legal pad with a black pen.

— The first three years are rhizome years, Mrs. Ber. Not above-ground years. The bamboo is building its underground infrastructure. The visible plant is incidental.

I had written that word down twice. Incidental.

We lost forty-seven rhizomes in the first month, which Dr. Tanaka had told me to expect. The rest took hold. By July, slender green spears had pushed up from three hundred and eighty-seven of the original five hundred. The cows ignored them, which was correct, because I had reinforced the four-strand barbed wire fence specifically to keep them out for the first three growing seasons. Dr. Tanaka had warned me that young bamboo could be killed if the cows browsed it before the canes were three years old. I had stretched the wire myself, with Joel holding the spool while I walked the line with a staple gun that my father had bought in 1957.

Joel didn’t ask any questions. He had stopped asking questions when his father walked out two years earlier. He had become, in the way that some children become, the small, quiet partner of his mother in everything she did. He was the only person on the farm who had not laughed at the bamboo, because Joel didn’t laugh at anything anymore.

Ruth laughed for all of us. She had cried for two months when Owen left, and then one morning in the summer of 1987 she had stopped crying and had started laughing again. I came to understand that Ruth had decided somewhere inside herself that the family needed someone to laugh, and she had taken on the job. She named every rhizome. By August, the second row of surviving plants had names too. I wrote them all in the notebook alongside the numbered map. Plant number forty-seven was Lottie. Plant number one hundred and twenty-two was Hyacinth. Plant number two hundred and sixty-eight was Tom Wells, named after a barn cat that had lived on the farm in 1986 and had disappeared the same week Owen left. Ruth insisted that the strongest of all the bamboo plants be named Tom Wells in his memory.

I did not argue.

My father, Jacob, found the rhizomes on the third morning after I brought them home. He walked out to the unheated mud porch where I had stored the cardboard flats, and he stood in the doorway with his hand on the frame and looked at them for a long time. Then he came back into the kitchen where I was finishing the breakfast dishes.

— Tilda.

— Yes, Dad.

— There is bamboo on the mud porch.

— Yes, there is. Five hundred pieces of bamboo. Five hundred rhizomes. There is a difference. The rhizome is the underground stem. The above-ground shoots will come from those.

He sat down at the kitchen table. He was seventy-one years old, his hands knotted with arthritis, his back bent from decades of bending to milk cows. He had sold the dairy operation to me in 1981 when he could no longer run it himself, and he had moved to the small house at the back of the property and let me run the farm my way ever since.

— Tilda, I’m going to ask one question.

— Yes, Dad.

— Did the man who sold you these have gray hair?

— He had black hair turning gray at the temples. He spoke to me for two hours after the lecture. He drew diagrams. He gave me his card. He has been studying this for thirty-six years.

Jacob nodded. He drank his coffee for a moment in silence. Then he said something I have thought about every day since.

— Your mother’s grandmother on her mother’s side, in the old country before they came to America in 1849, kept a stand of something the old people called Schlangenroar along the cow pasture. Snake reed. I used to think it was just a name. I have not thought about that word in fifty years, until you put bamboo on the mud porch this morning.

I was quiet for a long moment. I had never heard the word before.

— Tilda, I do not know if it was the same thing. The world is full of plants. The old people knew things that we have forgotten. I know that. I am not going to argue with you. But you should know that the people who will laugh at you are the same people whose great-great-grandmothers planted the same kind of thing along their own cow pastures in Switzerland and the Palatinate three hundred years ago. They have forgotten. You are remembering.

I did not respond. I finished the dishes. Jacob walked back to his small house. I stood at the kitchen window and watched the light spread over the north pasture, where the first shoots of bamboo were breaking through the soil like tiny green prayers.

The years 1990 and 1991 were years of waiting. The bamboo grew slowly above ground, but I could feel the rhizome network spreading beneath the soil, sending out its white, fibrous roots in every direction. The neighbors drove past and saw skinny green shoots that grew a little taller each year, and then a little thicker, and then, by the autumn of 1991, some of the canes were reaching eight feet. The laughter at the diner and the auction barn began to quiet. It was replaced by a kind of watchful silence, the way you watch a gambler who has bet everything on a long shot and you are not sure whether you want her to win or lose.

The first real proof came in February of 1992. The bamboo had reached a density of about four mature canes per rhizome, with average heights of twelve feet and a diameter of an inch and a half at the base. I cut the lower branches and harvested the leaves, following Dr. Tanaka’s instructions exactly. I mixed them with the regular silage at a ratio of about ten percent bamboo leaf to ninety percent silage, and I fed the mixture to the cows in late February.

I did not sleep the night before. I lay in bed and thought about everything that could go wrong. The cows could refuse to eat. The milk could come back tainted with an off-flavor that the dairy cooperative would reject. The cows could sicken. The leaves could contain some compound that Dr. Tanaka’s research had not accounted for in our specific soil and climate. I had staked my entire future on the word of a man I had met once, in a lecture hall, for two hours.

At four o’clock the next morning, I walked to the barn with Joel. He was fifteen now, tall and lean, his voice beginning to deepen. We milked the thirty-eight cows as we always did, and then I mixed the bamboo leaf supplement into the feed troughs. The cows ate. They did not hesitate. They did not sniff the feed and turn away. They ate exactly as they always ate, with the steady, rhythmic grinding of their jaws.

— Mom, Joel said, standing beside me at the bunk. They’re eating it.

— I see that.

— They’re not acting funny or anything.

— No, they’re not.

I measured the milk production every day for two weeks, keeping the records in my composition notebook with all the other numbers. The cows that received the bamboo supplement increased their production by an average of one point four pounds per cow per day. It was not a large increase. It was within the range of normal daily variation. But the bamboo had not hurt the cows. That was the first proof.

By the spring of 1992, the windbreak function was beginning to work. The north edge of the pasture, which had been scoured by winter winds for as long as Jacob could remember, was now sheltered by a fourteen-foot-tall and three-hundred-twenty-foot-long wall of dense bamboo. The south slope of the pasture stayed snow-covered for eleven additional days that winter compared to the previous five-year average, because the wind was not stripping the snow off the slope at the rate it had stripped it before. Snow cover meant moisture retention. Moisture retention meant that the spring grass came up earlier and thicker. We began grazing on April ninth of 1992. The year before, we had begun on April twenty-second. Thirteen extra days of pasture meant thirteen days of cows not eating from the silage bunker. When I did the math, it came to a savings of about six hundred and twenty dollars. The bamboo had begun to pay for itself.

I told no one. I wrote the numbers in the composition notebook. I underlined them. Then I closed the notebook and put it back in the kitchen drawer where Jacob had given it to me in 1972, and I went back to work.

The summer of 1993 brought the first real heat test. The temperatures that July climbed into the high nineties and stayed there. In previous summers, the cows had suffered badly in the afternoon heat. They would pant and drool and their milk production would drop by eight to twelve percent. It was one of the quiet costs of running a dairy without a proper shade structure, and I had never been able to afford to build one.

But that summer, I had opened a twelve-foot-wide gate at the midpoint of the bamboo wall, allowing the cows access to a small fenced area on the lee side of the grove, where I had planted a mix of cool-season grasses. The cows began, in the heat of July afternoons, to spend the midday hours in the bamboo shade. They lay down in the deep green light under the canopy and chewed their cud in the way that cattle do when they are comfortable. The heat stress they had shown in previous summers simply did not occur.

Joel noticed first. He stood at the kitchen window one afternoon, a glass of water in his hand, looking out toward the bamboo grove.

— Mom.

— Yes, Joel.

— The cows in the shade. They are not panting, not the way they used to.

I came to stand beside him. The cows lay quietly in the dappled shadow of the bamboo, their sides rising and falling in slow, easy rhythms. The air under the canopy looked cool and still.

— The bamboo is working, he said.

— I know it is.

— When did you know?

I looked at him. He was sixteen, almost as tall as I was, and his observations were becoming sharper than my own.

— The first time I read Dr. Tanaka’s diagrams in 1989.

— But you didn’t really know. You believed. That is different.

I was quiet for a moment.

— You are right. I believed. I did not know until last summer, when the snow stayed on the south slope longer than it had stayed in fifteen years.

We stood together at the window, watching the cows. The bamboo was working. The neighbors had begun to notice. The laughter was gone, replaced by a kind of cautious curiosity. They were not ready to ask questions yet. The asking would come later.

The years 1994 and 1995 were the difficult years. Milk prices fell again in 1994 to eleven dollars and sixty-two cents per hundredweight, the lowest real-dollar price since the Great Depression. Dairy operations across Lancaster County began to fold. The first to go was a sixty-five-acre dairy near East Earl that had been in the same family since 1893. The second was a one-hundred-ten-acre operation near Honey Brook. The third was a forty-eight-acre dairy near Bird-in-Hand, the smallest fully Amish dairy in the township. Each closure was announced quietly, with no fanfare. The cows went to auction. The land went to either the next-door neighbor or to a Philadelphia developer who had been buying Lancaster County dairy ground at four thousand two hundred dollars an acre and converting it into housing developments.

I sat at the kitchen table in March of 1994, after the children were asleep, and I ran the numbers. My operation was running on margins of approximately fourteen dollars per cow per month above operating costs, against a long-term need of thirty-two dollars per cow per month to cover capital depreciation, family living expenses, and the eventual replacement of the milking equipment. I was losing eighteen dollars per cow per month. With thirty-eight cows, I was losing nearly seven hundred dollars a month. The savings account that had reached eleven thousand two hundred dollars by the end of 1993 was being drawn down at a rate of eight thousand dollars a year. I had three years of savings left. I would lose the farm by the spring of 1997 if nothing changed.

I told Jacob in October of 1994. I sat at his kitchen table in the small house at the back of the property, and I laid the numbers out for him on a piece of paper.

— Dad, the dairy is not making it.

— I know.

— We have until 1997.

— I know.

He looked at his hands. They were seventy-six years old. He had farmed in some capacity for sixty-four of those years.

— Tilda, I have been thinking.

— Yes, Dad.

— The bamboo is now seven years old. It is producing more leaf than your cows can eat.

— Yes. There are operations in Asia that sell bamboo leaf as a livestock feed supplement. Dr. Tanaka has been writing to me about it. He thinks the American organic dairy market may begin to want bamboo supplementation within five years. He says the data is starting to support it.

— Tilda, there is also bamboo for human consumption. The shoots.

I was quiet.

— Asian-American populations in the cities. There are large Vietnamese, Korean, and Chinese communities in Philadelphia and New York and Washington, D.C. They will pay for fresh bamboo shoots. They will pay good money. The supply is currently almost entirely imported from China and Thailand in cans. There is no significant American fresh bamboo shoot market because there are no American producers.

I had been thinking about the same thing for three months. I had not raised it because I had not wanted Jacob to feel that I was abandoning the dairy.

— Dad. The dairy is going to die. The shoots will save the farm. Are you telling me to do it?

— I am telling you that your great-great-grandmother kept Schlangenroar along the cow pasture in the old country. I am telling you that you are a forty-four-year-old Mennonite woman who does not yet know how to call a Vietnamese grocer in Philadelphia and ask if he wants fresh bamboo shoots. I am telling you that the man who sold you the rhizomes is named Hideo Tanaka and that his card is in the drawer of the desk in the office. I am telling you that Joel is seventeen and that he is going to leave the farm in eighteen months and that you are going to need a new partner. I am telling you that the new partner is going to be Hideo Tanaka.

I did not respond. I walked back to the main house. I made myself a cup of tea. I sat at the kitchen table for an hour. Then I took a piece of paper from the drawer and a pen from the jar beside the stove, and I wrote a letter to Dr. Hideo Tanaka in São Paulo, Brazil.

I mailed it the next morning at the post office in New Holland. The postmaster, a woman named Vera Krider who had known me since we were girls, looked at the address on the envelope and looked at me and did not say anything. She weighed the letter, printed the postage, and handed me the receipt.

— Thank you, Vera.

— You’re welcome, Matilda.

That was all.

Dr. Tanaka’s response came in early December. It arrived in a thick airmail envelope with a Brazilian stamp and a postmark from São Paulo. I carried it into the kitchen and opened it with shaking hands. Inside was a fourteen-page typed letter in his careful, Portuguese-accented English, outlining a plan for converting my bamboo planting into a commercial fresh shoot operation supplying the Asian-American restaurant and grocery markets in Philadelphia. The letter included projected harvest yields, infrastructure requirements, a list of three Vietnamese wholesalers in Philadelphia whom he had personally contacted on my behalf, and a list of names of agronomists in Brazil who would be willing to consult by mail at no charge.

At the bottom of the fourteenth page, he had added a personal note.

“Mrs. Ber, I have thought about your question for two months. I am sixty-five years old now. I am at the end of my own work in Brazil. I have one son who is grown and who does not farm. I have spent thirty-six years developing knowledge that has in the United States exactly one person who has acted on it. That person is you. I would like to come to Pennsylvania for two weeks in March of 1995 to help you set up the conversion. I will pay my own travel. I do not require compensation. I require only that you allow me to spend two weeks watching what you have built. Sincerely, Hideo Tanaka.”

I read the letter three times. I showed it to Jacob. I showed it to Joel. I did not show it to anyone else. I wrote back that same night, accepting his offer.

Dr. Tanaka arrived at the farm on March eleventh, 1995. I met him at the train station in Lancaster, standing in my dark blue dress and white prayer covering, scanning the faces of the passengers as they stepped onto the platform. I recognized him immediately from the conference—a compact man with black hair now fully gray, glasses, and a quiet, patient expression. He carried a single suitcase and a leather satchel stuffed with papers.

— Mrs. Ber.

— Dr. Tanaka. Welcome.

We shook hands, and I felt the roughness of his palm, the hands of a man who had spent his life working with plants. We drove back to the farm in the 1992 Chevrolet pickup I had bought the previous year to replace the old Plymouth station wagon. Dr. Tanaka spent the drive looking out the window at the rolling green fields and the barns and the silos, and when we pulled into the driveway and he saw the bamboo grove for the first time, he did not speak for a full minute.

— Mrs. Ber, he said finally. You did exactly what I told you.

— Yes.

— The planting depth. The spacing. The fence. The three-year waiting period. You followed every instruction.

— I wrote them all down.

He turned to look at me, and I saw something in his eyes that I had not seen in a long time. It was not surprise, exactly. It was recognition. The recognition of one careful person meeting another.

He stayed in the small guest room in my house. He spent twelve days walking the bamboo grove with me and Jacob and Joel. He took two hundred photographs with a small camera he carried in his satchel. He took soil samples and rhizome samples and packed them in small plastic bags with handwritten labels. He measured every cane, recording the height and diameter and leaf density in a notebook of his own. He drew diagrams of the rhizome network on large sheets of graph paper, showing me how the original five hundred rhizomes had spread underground to produce a stand of approximately sixty-four hundred mature canes covering one point four acres.

— This is better than I expected, he said on the third day, kneeling in the dirt with a tape measure in his hand. The soil here is limestone-based, well-drained. The bamboo likes it. The rhizome health is excellent. You could expand to four acres by next spring if you divide the rhizomes now.

— How?

— Lift and divide. The stand is producing approximately eight hundred dividable rhizomes per year. You do not need to buy new stock. You only need labor.

We did the expansion ourselves over the spring and summer of 1995. Me, Joel, Jacob, and Ruth, who was now fifteen and as strong as any of us. We planted the new rhizomes along three new fence lines, following Dr. Tanaka’s diagrams exactly. The work was hard. We woke before dawn, milked the cows, and then spent the rest of the day digging holes and lifting rhizomes and hauling water. My back ached. My hands blistered and calloused and blistered again. But every evening, when I walked out to look at the new plantings, I felt something I had not felt since Owen left: the quiet hum of hope.

Dr. Tanaka also spent four days driving with me to Philadelphia. He had set up appointments with the three Vietnamese wholesalers he had contacted. The first wholesaler was a man named Phuoc Quan, who ran a fresh produce supply company in South Philadelphia called Saigon Produce Market. He had been in the Philadelphia restaurant supply business for twenty-two years. He had been buying canned bamboo shoots from a Thai exporter for the entire twenty-two years. He had never, in all that time, found a domestic American supplier of fresh bamboo shoots.

We met him in the back office of his warehouse, a cramped room lined with invoices and produce catalogs. Mr. Quan was a thin man in his fifties, with sharp eyes and a quick, precise way of speaking. He listened to Dr. Tanaka explain the bamboo operation in Pennsylvania. He looked at the photographs of the grove. He asked four questions.

— The shoots will be fresh?

— Yes, I said. Cut at sunrise and delivered by noon.

— The first delivery will be when?

— April of 1996.

— You have the volume capacity to supply consistently?

— Yes.

Mr. Quan set the photographs down on his desk. He looked at me for a long moment, and I felt the weight of his assessment, the calculation of a man who had built a business by making careful bets.

— Mrs. Ber, I will buy your entire production for the first three years at three dollars and twenty cents per pound.

I did the math in my head. Three thousand pounds in year one, scaling to ten thousand pounds by year three, at three dollars and twenty cents per pound, would gross nearly ten thousand dollars in 1996 and rise to thirty-two thousand dollars by 1998. Against the dairy losses, against the savings account that was bleeding dry, the numbers came into alignment like the tumblers of a lock clicking into place.

— I accept.

Dr. Tanaka and Mr. Quan shook hands across the small wooden table. I did not shake hands, because Mennonite women did not shake hands with men outside the family, but I nodded, and Mr. Quan nodded back, and the deal was made.

Dr. Tanaka returned to Brazil at the end of March 1995. I drove him to the train station in Lancaster, and he stood on the platform with his suitcase and his satchel, and he gave me one final instruction.

— Write to me if you have any questions. Any at all. I will answer.

— I will.

— Mrs. Ber, you have built something that no one else in this country has built. Do not let anyone tell you that it is not important.

He boarded the train, and the doors closed, and I stood on the platform until the train disappeared around the bend. Then I drove home and went back to work.

The first commercial harvest came on April sixth, 1996. We woke at four o’clock in the morning, me and Joel and Ruth, and we walked out into the gray predawn light with sharp knives and plastic buckets. The bamboo shoots were pushing up through the soil, pale green and tender, and we cut eighty-four pounds of them between five and eight o’clock. We washed them in the milk house sink, packed them in cardboard produce flats, and loaded them into the back of the pickup truck. Joel drove the load to Philadelphia, and Mr. Quan weighed the load at eighty-four point four pounds and paid me two hundred sixty-nine dollars and ninety-three cents in cash.

I put the money in the kitchen drawer, next to the composition notebook, and I stood there for a long moment with my hand on the drawer pull. The dairy operation was in its final stages. Milk prices had fallen to eleven dollars and forty cents per hundredweight that spring. Two more Lancaster County dairies had closed in the previous six months. My savings account was down to two thousand four hundred dollars. I had four months of operating cash.

But the bamboo shoots kept coming. In that first April-through-June season, we harvested twenty-seven hundred and forty pounds, grossing over eight thousand dollars. By July, the shoot revenue had stabilized my cash position. By October, I had stopped milking ten of my older cows and sold them at the New Holland auction. I reduced the herd to twenty-eight. By December, I reduced it to twenty-two. The dairy operation was no longer losing money on a per-cow basis, because the fixed costs were spread across a smaller herd that was still producing milk profitably enough to cover its own variable costs. The bamboo was covering everything else.

By the spring of 1997, the operation was financially stable for the first time since 1985. I was fifty years old. Joel had finished high school the previous May and had taken a job as an apprentice carpenter in Lancaster, working for a Mennonite contractor named Aaron Hostetler. He continued to live in the farmhouse and to help with the morning milking and the bamboo harvest. Ruth was seventeen and had decided, in the fall of 1996, that she wanted to study agronomy at Penn State. She applied. She was accepted. She was the first member of the Ber family in three generations to attend a four-year college.

I did not object. Jacob did not object. The community did not openly object, although some of them murmured at Sunday dinner about whether a Mennonite girl ought to be sent to a state university by a mother who had walked away from regular church attendance a decade earlier. The murmuring did not reach Ruth. She went to Penn State in August of 1997, her trunk packed with clothes and books and a small pot of bamboo that she had propagated from one of the original 1989 rhizomes. She came home for every break. She helped with the harvest. She had decided by her sophomore year that she was going to come back to the farm permanently after graduation and expand the bamboo operation into a research and demonstration site for other small dairies trying to diversify out of declining milk markets.

The bamboo grove by the year 2000 covered seven and a quarter acres. The shoot revenue had passed forty thousand dollars. The dairy was down to eighteen cows. The combined operation was earning a net of approximately fifty-four thousand dollars per year, against a Lancaster County dairy industry that had lost roughly forty percent of its operations between 1985 and 2000.

One Saturday afternoon in July of 2000, Vernon Lapp drove past the farm and saw the bamboo grove from the township road. The grove was twenty-two feet tall. It stretched along three of the four sides of the original pasture. There were Asian-American customers driving up the lane in cars with Philadelphia and Baltimore plates, who had begun in the previous year to come directly to the farm to buy fresh shoots in late spring. There was a small wooden farm stand at the end of the driveway with a hand-painted sign reading “Ber Family Bamboo.” Ruth had painted the sign in the spring of 1999.

Vernon stopped in the driveway. He had not stopped at the Ber farm in eleven years. He sat in his truck for ten minutes. Then he got out. He walked up to the kitchen porch. I came out and stood on the steps.

— Vernon.

— Matilda. I owe you a conversation.

— You do not owe me anything, Vernon.

— I have been driving past this farm for eleven years, thinking that one of these years it would go under, and that the bamboo would be remembered as the saddest thing that happened to any dairy widow in Lancaster County. I have stopped today because the farm has not gone under. The farm has gotten bigger. The bamboo is bigger than my barn, and there are people from Philadelphia driving up your lane to buy something they cannot get anywhere else in this state.

He paused. His hands were clenched at his sides, the knuckles white.

— Matilda, I owe you a conversation. I am asking permission to have it.

I was quiet for a long moment. I had not seen Vernon Lapp on my porch in eleven years. I had not exactly been waiting for him. But I had not exactly not been waiting, either.

— Vernon, you can come in. I will make coffee.

He came in. We sat at the kitchen table. We talked for two hours. Vernon admitted, slowly and with the careful word choice of a Mennonite man who has thought for a long time about what he wants to say, that he had been wrong in 1989. He admitted that he had been wrong every year between 1989 and 2000. He admitted that the laughter at the prayer breakfast had been the worst thing he had personally done in his adult life, because the laughter had come at a time when I was carrying a load that none of them had been carrying, and the laughter had made the load heavier.

He apologized. He did not ask to be forgiven. He simply apologized, and he sat with the apology, and he did not try to soften it or qualify it or make it about anything other than what it was. His voice broke twice. I saw the tears in his eyes, and I saw the way he did not try to wipe them away.

— Vernon, I said when he was finished. I accept your apology.

— You do?

— Yes. I forgave you a long time ago, even if I didn’t know I was doing it. Holding on to that hurt would have been a heavier load than the bamboo ever was.

He nodded. We drank a second cup of coffee. He left. He came back two weeks later with his wife, Susanna, and a peach cobbler. He came back four times in the next year. By 2002, he was helping with the bamboo harvest twice a week. He was the third person, after Dr. Tanaka and Calvin Stoltzfus, who had come to understand what I had built without having to be told.

The community came back slowly. Not all of it. The Old Order Amish never participated, because the Old Order does not participate in commercial enterprises beyond their own community. But several Amish families became regular customers of the bamboo shoots, which they used in soups during Lent. The progressive Mennonite community returned in stages. By 2005, I was attending services at Weaverland Mennonite once a month, a compromise I had reached with myself and with the community after a long conversation with the new pastor in 2003 about what kind of attendance was meaningful for me.

Ruth graduated from Penn State in May of 2001. She came home. She married a man named Reuben Yoder in 2003. Reuben was a Mennonite carpenter who had grown up in Ohio and had come to Pennsylvania to apprentice with the same Aaron Hostetler that Joel was working for. Reuben moved to the farm in 2003. He built a new packing shed for the bamboo operation. He built a small commercial kitchen for processing pickled bamboo shoots, which became the second product line of the farm in 2005. Joel got married in 2006 to a woman named Emma Bichy. He moved to her family’s farm near Lititz. He continued to drive over every Saturday morning to help with the harvest.

By 2010, the Ber family bamboo operation was the largest fresh bamboo shoot supplier on the east coast of the United States. We were supplying eleven wholesalers across Philadelphia, Baltimore, Washington, D.C., and New York City. The annual revenue had passed three hundred forty thousand dollars. The operation employed three full-time workers and six seasonal harvest workers.

Dr. Tanaka’s son, Kenji, visited from Brazil in 2008. He was a quiet man in his forties, with his father’s glasses and his father’s patient way of listening. He stayed for two weeks. I gave him his father’s photograph and his father’s original 1989 sales receipt for the rhizomes. He sat at the kitchen table and held the receipt in both hands, and he cried. I did not say anything. I just sat with him and let him cry.

He took a sample of one of the original 1989 rhizomes back to Brazil and planted it in his father’s old propagation nursery, which he had taken over after his father’s death and renamed in his father’s memory. The rhizome survived the trip. It grew. By 2010, it had become a fourteen-foot-tall stand of bamboo at the front gate of the nursery, with a small bronze plaque at its base reading “Ber Tanaka 1989.” Ruth had suggested the plaque. The Ber family had paid for it.

I never saw the plaque in person. I never traveled outside of Pennsylvania except to Philadelphia for deliveries. I did not have any particular desire to travel. The farm was where I belonged. The farm was where the bamboo was.

Jacob died in his sleep in March of 2007. He was eighty-eight years old. His funeral was held at Weaverland Mennonite Church. I attended. The community attended. Vernon Lapp gave one of the readings. The reading was from Ecclesiastes. The reading was about seasons and times. Vernon’s voice broke twice during the reading. He had become, in the seven years since his apology in my kitchen, one of Jacob’s closest friends. Jacob had forgiven him without ever needing to be told that there was anything to forgive.

I continued to run the operation through 2018. By then, I was seventy-one. Ruth and Reuben took over the daily management. I moved into the small house at the back of the property where Jacob had lived. I continued to walk the bamboo grove every morning until 2023, when I was seventy-six.

My granddaughter Esther, who was Ruth and Reuben’s third child, born in 2009, walked the grove with me every morning starting in the summer of 2017, when she was eight and I was seventy. She asked questions. I answered them. She wrote the answers in a composition notebook I gave her in the summer of 2018, when she turned nine. The notebook was the same kind that Jacob had given me in 1972.

Esther was, at age fourteen in the summer of 2023, the fourth generation of her family to learn the bamboo from someone who had learned it from someone before. Dr. Hideo Tanaka had given his knowledge to me. I had given it to Ruth. Ruth was giving it to Esther. The knowledge had crossed an ocean once, in a thick airmail envelope in December of 1994, and had crossed it again in the rhizome that had been planted in São Paulo in 2008. The knowledge had come before that from the Brazilian agronomy of the 1960s and 1970s, and before that from the Japanese forestry traditions that Dr. Tanaka had studied in Hiroshima in the 1940s, and before that from the Chinese bamboo forestry traditions documented as far back as the third century B.C., and before that from the simple observation by farmers in three different continents over thirty centuries that bamboo and cattle could share a landscape if the cattle were managed thoughtfully and the bamboo was given time.

The knowledge had also come, in some smaller and less documented way, from the Schlangenroar that my great-great-grandmother had kept along her cow pasture in the Palatinate three hundred years before, in a time and place where the word for any reedy plant that protected livestock was a kind of universal word that did not need translation across regions, because every farmer everywhere understood what it meant.

I had not known about the Schlangenroar until my father told me about it on the third morning after I brought the rhizomes home. I had thought since that morning about what it meant that the word had survived in my father’s memory across three centuries of immigration and forgetting, and what it meant that my father had forgotten the word until he saw bamboo on the mud porch, and what it meant that the forgetting could be reversed in a single morning by the simple sight of a plant that the old people had kept and the new people had stopped keeping.

The plants we forget are still in our memory somewhere. I had come to believe that. They wait. They wait for someone to bring them home.

The community in Lancaster County by 2023 had stopped being a community that laughed at people who planted strange things along their pastures. The community had become, in the years between 1996 and 2023, a community that had watched several of its members do unconventional things and had seen those unconventional things save several farms. The community had not exactly become open to all unconventional ideas. It was still a Mennonite community. It still had its own slow process for evaluating new things. But the laughter at the prayer breakfast in April of 1989, which had felt so total and so permanent at the time, had become something the community no longer talked about, because the community had come to understand over thirty-four years that the laughter had been a mistake.

Mistakes are not erased in Mennonite communities. They are simply absorbed into the long memory of the place.

I walked the bamboo grove with Esther in the summer of 2023. She was fourteen. I was seventy-six. The grove covered eleven acres. The cane heights reached twenty-eight feet. The original 1989 planting was still there, still producing, still throwing up new shoots every spring. The two hundred thirty-five surviving original rhizomes from 1989, which Ruth had once named in her composition notebook, were now the great-great-grandparents of a stand of approximately eighty-four thousand cane stems across all the Ber family bamboo plantings in the eastern United States. The Ber family had begun in 2015 to license rhizome stock to other farmers in the region under the “Ber Tanaka” name. There were now nineteen commercial bamboo shoot operations in Pennsylvania, New Jersey, Maryland, Virginia, and southern New York. Every one of them had started with rhizomes from our farm. Every one of them was descended from the original five hundred rhizomes that Hideo Tanaka had brought from his propagation nursery in Brazil in March of 1989. Every one of them carried, in some sense, the genetic memory of a Japanese-Brazilian agronomist who had told a Mennonite woman in a Pennsylvania lecture hall on the second morning of a forage conference that he had not in thirty-six years met an American farmer who had asked him an intelligent question.

Esther asked questions in the summer of 2023. She asked good ones. She had read all the composition notebooks. She had read Dr. Tanaka’s letters. She had read the unpublished manuscript that his son had sent in 2003, which was now bound in a small leather cover in the kitchen drawer. She knew the names of the original two hundred thirty-five rhizomes that Ruth had named in 1989. She walked among them and called them by name.

— Tom Wells. Lottie. Hyacinth. Eliza.

We walked in silence for a while, the bamboo towering above us, the light filtering down through the canopy in long green shafts.

— Grandma?

— Yes, Esther.

— The thing you said about Schlangenroar. Have you ever wondered if there are other things like that? Other plants the old people kept that we have forgotten?

I was quiet for a moment. I walked with her through the row of canes that had been Ruth’s first row in 1989. The row where Tom Wells still grew. The row where a thousand new shoots had risen from the rhizome network that year.

— Esther.

— Yes, Grandma.

— I have wondered every day for thirty-four years.

The laughter at the prayer breakfast in April of 1989 had not been about bamboo. The laughter had been about the unfamiliar. The laughter had always been about the unfamiliar. The thing the community had not understood in 1989 was that what looked unfamiliar was in fact ancient. The bamboo was not new. The bamboo had been kept by farmers for three thousand years. The community in Lancaster County had simply forgotten what its own great-great-grandmothers had known, and the forgetting had been so thorough that when one woman remembered, the remembering had looked to all the others like madness.

I thought about this often. I thought about it again in the summer of 2023, walking with Esther through the rhizome bed at the north fence line of the original pasture. I thought about how many other plants and practices and small accumulations of knowledge were waiting somewhere in the memory of someone’s grandfather, somewhere in the unread pages of someone’s manuscript, somewhere in the back rows of a forage conference where a sixty-five-year-old agronomist with gray at the temples was speaking to a polite and uninterested room.

The plants we forget are still there. The knowledge waits. The waiting is not a tragedy. The waiting is simply what knowledge does when there is no one yet ready to hear it. The community will laugh sometimes for seven years, sometimes for longer. The laughter is not the end of the story. The laughter is only the middle.

The end of the story is what happens after the laughter has died. When the bamboo has reached twenty-eight feet, when the great-granddaughter is walking the grove with her great-great-grandmother’s word for it on her tongue, and when the snake reed and the bamboo and the eucalyptus and the apple and the prairie fire and the hundred other forgotten things are all at last remembered together, and the farm is fed by what it had always known how to grow but had stopped knowing for a while.

That is the lesson. That is the only lesson I ever cared to give. And I gave it to Esther in the summer of 2023, walking among the canes, saying the names of the plants that had saved us, and remembering
