Berkeley Horticultural Nursery carries an extensive variety of seed.

Thanks. We just came back from Berkeley :( Anywhere else in the city?

Well, if you don't mind tootling up to Petaluma, Baker Creek Heirloom Seeds has a store there (called The Seed Bank) on the corner of N. Petaluma Blvd. and Washington. They have the two varieties you mentioned and are reasonably priced. I love that place.

Edited to add: I think I should warn you they're closed on Saturday.

Lelia: Thanks so much for the tip. You are right, I saw they were closed today :( but I put them on my list of places to visit on the next trip. Thanks so much
