Joylynn, this is one of those great
perennial vegetables you can plant from seed. Quite a few places have them now, one of them is
Fedco Seeds here in Maine. They mention my friend Aaron Parker and he sells them at his nursery
Edgewood Nursery as both seeds and plants and has very decent prices. I think Aaron might be a member here. If I don't eat every last floret and I can remember I may be able to get you some seeds.
I like in Fedco's description them using the florets in stir fries....must do that! The mature leaves are more than I can handle, even when cooked, but perhaps would be good in a mixed dish to make it interesting. Personally I need to even cook the young leaves.
