Here's one of those almost secret government projects, and how to use it to get seeds that are often very rare and not available in any seed catalog, anywhere. Packets are small- but enough to start your own seed saving-but cost is $0. This is probably the biggest seed catalog in the world- 7,943 varieties of tomato, 639 kinds of radish- you get the picture. You should have a scientific name, if you want to just look at all the corn, or a variety name, if you want to find out if some old seed is really extinct. You can also look under the state of origination for varieties suited to your climate. Go to: www.ars-grin.gov/npgs/searchgrin.html Once there, go to "accession area queries". you can search for your seed in various ways. Once you find some seed that you just have to have, write down the PI number or other identification number and the station where that variety is maintained. Now go back to the main GRIN page (above link) and click on "request germplasm" and fill out the request form. I'm getting beans, corn, and a squash, all not available in the US (That I can find). Requested the beans on 30 Dec and got them 4 Jan. One of the beans is Blue Coco which is blue and turns green when cooked and is the "best flavored" green bean, according to the USDA testers.
