adapted from A Seed Saving Guide for Gardeners and Farmers, Organic Seed Alliance Life Cycle: A = annual, B = biennial Selfing or Outbreeding: VS = very self-pollinating, S = somewhat self-pollinating, SO = can be self-pollinating, but is often outbreeding, O = mostly outbreeding, VO = requires outbreeding Isolation Distance: isolation distances are for home gardener use and will eliminate cross-pollination MOST of the time – however, more distance may be advisable if absolute purity is required Population Size: keep in mind that the listed population sizes are for commercial production; home gardeners may have to grow fewer plants as garden space dictates, though particularly rare varieties should be grown close to recommended population sizes Maturity: market = seeds are ready when fruit is ripe, after = seeds mature after fruit/plant is typically eaten (if listed as ‘market or after,’ market refers to a dry market stage (such as dry beans, flint/flour/pop corn, soup peas, etc).
