Sources of Plants and Seeds
Perennial vegetables can be hard to find. The nurseries and seed companies that stock them are usually small and run by highly dedicated enthusiasts. In some cases only one or two companies in North America offer the species you are looking for. Be prepared for some quirky or technical catalogs – but ones that are chock-full of fascinating plants.
Someday more perennial vegetables may be available through mainstream companies. While this will help many more people grow them, please don’t forget the pioneering companies and organizations that first made these crops available to you.
During the course of writing Perennial Vegetables, two of the finest perennial vegetable nurseries – Oregon Exotics and Future Foods - went out of business. This should be a lesson to us all not to hold back on ordering something rare, because it may be very difficult to find again if a company goes under.
Several books and organizations can help you track down rare plants and seeds. Check out:
