"Not all that long ago, seeds for heirloom vegetables were hard to find. Fortunately, that is changing. Several seed companies now specialize in heirloom vegetables. Others offer a mix of old-timers and modern varieties. As hopeful as this trend is, many heirloom vegetable varieties are threatened and may soon become extinct. Still, there is time to save these plants. All it takes is a patch of land (or a container), water, sun, and some seeds. The rest is up to you.

"Here are a mix of commercial seed companies, museums, and non-profit organizations that sell heirloom vegetable seeds, and the things you need to grow them. I selected these particular sources because I've had good experiences with them, or have heard good things about them from my sources. I list them here for informational purposes only, without any guarantees. There are, of course, many other fine sources of heirloom seeds.

"Note: Many heirloom vegetable varieties are not available in the seed trade, but can be found through seed saving networks. For more information, see also: Seed Savers, Seed Exchanges, and Seed Societies" From The Heirloom Vegetable Gardener's Assistant
