Meyer Seed in Baltimore, whom I've dealt with only peripherally, and Landreth in Pennsylvania (I'll write about them in another post). And then there's Southern Exposure Seed Exchange, in earthquake-central Mineral, VA.
What makes Southern Exposure different from all those other purveyors of organic-friendly, open-pollinated seed? For us Marylanders, it's location, location, location. They make a point of emphasizing seed that's tested and does well in the Mid-Atlantic. Varieties that can deal with our climate are marked with a sunny little symbol in the catalog. There's a low-key, friendly-neighbor feeling to the recycled-paper catalog illustrated with both photos and color drawings. The selection is ample enough to make you take time over decisions; the descriptions are good; and the prices are reasonable. ($2.50 for that Brandywine Sudduth's Strain tomato, with at least 40 seeds in the packet.) This is a good place to find lots of choices for lima beans, Southern peas, okra, collards and other specialties of the South, as well as plenty of tomatoes and... well, just about everything else too.
Look for the extra-winter-hardy greens developed by Brett Grohsgal of Even' Star Farm in St. Mary's County, MD.
Cooperatively-owned Southern Exposure sponsors the Monticello Heritage Harvest Festival each September - a great event!
