Looking For Ideas On Making A Perennial Vegetable/Herb Garden

I want to make a perennial vegetable and herb garden. I would like to get some ideas of what other people have done.

I certainly don't have the experience, but I have found the work done by these guys quite inspiring: http://perennialvegetables.org/.

Details regarding your climate, etc., might also help somebody answer your questions.

Some "perennials" I am planting this year:
-Rhubarb
-Sunchokes
-Sea kale

I am also on the lookout for
-Edible Hostas
-Giant Solomon Seal


There are many others, and the above might not work for your situation.
