I had brown wet clay in PA...not all that far from you actually...but here I'm on even heavier, thicker, and slicker red clay. Whole different beast! Though the zones are close...6b winter here and hotter than hades in the summer. Horribly humid too.
Nice list! I've grown some of those in PA and they did well for me there.
I'm so desperate for their new catalog to arrive I was reading and marking up last year's catalog the other night. Hoping to get a head start! Probably a good thing I don't live close to any seed places like that. I go a little crazy with seeds....about like going shopping for fabrics or yarns!
