How's that for a convoluted subject line?

I have a really big flower bed in the front yard that was mostly bright shade. My neighbor had a HUGE oak removed -- so now I have sun. I'm thinking of mixing in some veggies here and there. I know what to do for my run-of-the-mill vegetables.

But I am also considering trying asparagus and artichokes. These require a perennial bed set-up, right?

Have any of you grown these veggies? Would they do well as garden neighbors?

Next question -- I want some humongous Jo Pye weed. Can it be grown from seed? Or better started as a plant? Where can I find some?

Thanks! I'm gettin' itchy to get out in the garden!!!!!!!!!!!!!!!!!
