Seeds Link One Woman to Her PastIn her sprawling Iowa garden, Harriet Ausable grows her own heritage. There are the 'Rattlesnake' beans and 'Tall Telephone' peas grown from seeds from her maternal grandmother. And the 'Brandywine' tomatoes that remind her of the juicy fruits she ate as a kid.
Ausable is part of a growing trend in gardening: growing open-pollinated heirloom vegetables and flowers. These are varieties that, unlike hybrids, have the ability to cross-pollinate among themselves and produce seeds that will grow into plants similar to the parent variety. Growing open-pollinated varieties helps preserve the genetic diversity of plants under cultivation at a time when more and more agricultural land is dominated by just a handful of varieties. For example, only two pea varieties account for 96 percent of the U.S. crop. Growing heirloom seeds also opens up a world of possibilities for the adventurous gardener, from purple tomatoes and orange peppers to striped beets and long, tapered radishes. Ausable saves many of her own seeds, especially peppers, beans and tomatoes. The rest she buys from seed companies or trades with neighbors. "It's more interesting when you have different varieties and everything isn't the same," she said. "I suppose sameness is expected in the grocery store, but not in my backyard."
