Seeds of Change is a company that sells some heirloom varieties of vegetables and flowers. You can easily find their seeds in garden centers and also natural food stores. If you want to order online, there are lots of sources.
Most seed companies today have at least some heirloom varieties. Burpee Seeds even has them in its retail store displays. I ordered several interesting-looking varieties from Johnny's Seeds this year. They probably have the most extensive selection of all the more-or-less "mainstream" vendors. And then there's http://www.seedsavers.org/ -- well worth a look.
I got almost all of my heirloom seeds from Jung's this year. I like their prices and their service is outstanding. The pumpkin and muskmelon seeds had a poor germination rate and when I called them, they sent new packets right out to me.

Thank ya'll, I'm going to check these out ASPS. After I close the store this evening, I'm going to check at Wal-mart. I hate to work when it is this pretty and warm. Going to try and find some Moonflower and Cosmos seed.
