Where do you folks get your nitrogen fixing herbaceous seeds?

I'm working on building a swale and hugelkuture-berm system for my zone 2. I need to seed the berm with nitrogen fixers by spring, and am wondering what companies you recommend as to get the seeds?

The grocery store.

Lentils, chick peas, dry green peas, cowpeas, etc. I buy them by the bag, soak, then wing them out. My hugelkultur bed is seeded solely with bagged dry legumes this year.

I've also scored nitrogen-fixers from the oriental/Indian markets. Fenugreek, pigeon peas and others are easily available.

And my amaranth, quinoa, rye, wheat and amaranth seeds came from the bulk bins at a local organic market.

Cheap, cheap, cheap and the germination rates have been more than acceptable.

If you are talking about ground covers like clovers, I would suggest getting them locally. You can get a lower price on the internet, but when you add the shipping on 25-50# bags, have you really saved anything?

For N fixing trees and shrubs, either of these two will give you good selections,and fair prices:
