MEXICO, Mo. - A national tomato growers' supply company honored a Missouri Advanced Master Gardener this spring by selling tomato seeds she saved for decades.
On the cover of its 2017 catalog, the Tomato Growers Supply Co. features "Mrs. Maxwell's Big Italian," an heirloom beefsteak tomato prized for its flavor. The dark pink tomato is the result of seed-saving by the late Sally Maxwell, of Mexico.
"Heirloom tomato varieties have become increasingly popular among gardeners," University of Missouri Extension horticulturist David Trinklein said. "In addition to being prized for their taste, many heirlooms have historical significance and sentimental value, having been passed from generation to generation over the years."
Sally Maxwell's son, Tom, grows "Mrs. Maxwell's Big Italian" at Maxwell Garden with his spouse, Calvin, owner of Mackey Produce. Like his mother, he saves a limited amount of seed each year from the first and best tomatoes.
Tom Maxwell, 59, said he follows the same practices his mother used for more than 50 years. She received the first tomato seeds from a German immigrant neighbor, Mrs. Shoup. The seeds originally came from Italy.
Saving seeds is a demanding process.
"It is a mega-space-, mega-time-consuming operation," he said. "It's not just a thing that you wake up one morning and decide to do."
His desire to honor his mother inspires him to carry on the practice.
Maxwell slices tomatoes and removes the seed and gel from the tomato cavities. He washes off the gel and puts the seeds on paper plates to dry. After they dry, he covers the seeds with paper towels and stores them in containers with packets of silica gel and refrigerates them.
He starts the tomato seeds in well-ventilated high tunnel and conventional greenhouses. He places seeds in a mix of soilless medium and compost in packs. After they grow tall enough, he plants them in a garden isolated from other tomatoes to prevent cross-pollination.
Once a thriving business, Maxwell Garden remains open but serves fewer customers.
"Most mom and pop operations don't make money anymore," Maxwell said. "It started as a hobby and grew and grew. Now I've got it back down to a hobby."
Maxwell's parents, Harold and Sally, started the greenhouse in 1969 at their farm between Rush Hill and Laddonia. They gave excess plants and produce to friends and neighbors. By 1974, word spread about the flavorful "Mrs. Maxwell's Big Italian" tomato, and the Maxwells could no longer keep up with demand. They sold produce at the farm and on Mexico's town square.
After Harold's death, Sally and Tom moved to the current location. Sally worked at the greenhouse until her death at 96, even after severe osteoporosis made working difficult.
Sally Maxwell is a Mexico gardening legend, according to Sue Priest, a master gardener and retired teacher. By the time she was 4 years old, Sally noticed differences in how some weeds grew. She experimented with ways to get the less prolific ones to grow better. Her love of growing plants continued to grow throughout her lifetime.
Her farm and yard burst in bloom each spring and summer with prized day lilies and other flowers. Each year, the Maxwells hand-propagated 100 or more geraniums from a rosebud geranium passed down from Sally's aunt. "Slipping Day" took precedence over everything else - including Christmas dinner. Many, including Tom, still grow the geranium with its delicate buds.
Priest said Sally gained acclaim in Mexico for her obsession with "dead-plant" trips. She would buy hundreds, sometimes thousands, of dollars of discounted plants and revive them. "She was very giving with her flowers," Priest said. She also did not like conflict of any kind and used her gentle spirit to bring gardeners together, she said.
Sally and Harold shared a love of reading books about horticulture each evening. They often attended classes at the University of Missouri and through MU Extension to learn how to improve floral and vegetable production on their farm. They regularly volunteered at MU Extension 4-H fairs and flower and vegetable shows.
"Their garden was their playground," Tom Maxwell said.
Sally was in her 80s when MU Extension horticulturist Jim Jarman offered Mexico's first master gardener class in 2004. She, Tom and Calvin were in the first class of 12. The Mexico club formed in 2005 and Sally remained active in it until her death. She had only one request when preplanning her burial. She wanted to be buried wearing her Master Gardener pin. Even in death, she wanted to remind others of the joy gardening and Master Gardener membership meant to her.
"I told someone that when Sally got to heaven, God better get some more dirt," Priest said.
Maxwell's Mexico greenhouse serves as a gardening haven and informal social club for Mexico Master Gardeners, including a retired bookkeeper, teacher and engineer.
