FYI, a great seed source is NAYLOR SEED in NE Iowa. They are a third generation family seed company that's been in business since 1920. We've been buying all of our seed needs from Naylor's as long as I can remember. If they don't list it, they can get it. You can have your local supplier check'm out or buy direct at www.naylorseed.com or give'm a call at 1-800-747-SEED.
