Sure, you can buy your usual packet of Straight Eight cucumber seeds at the hardware store again this spring (boooooring), or you can spice up your garden with some Boothby’s Blondes or Hmong Reds from the Maine Organic Farmers and Gardeners annual gathering of seedies. It’s like a flea market for fruit and vegetable nuts, where more than two hundred folks freely share seeds and scions from their gardens and orchards. Maine’s own Johnny Appleseed, John Bunker, usually shows up with hundreds of apple scions — grafting wood for fruit trees — salvaged from long-forgotten varieties, such as Black Oxford, famous for its keeping qualities, and Chestnut, an incredibly sweet early crab apple. You don’t even have to bring your own seeds. There’ll be workshops to teach you how to save your own for next year.
