I would really like to find some perennial greens I can use in large quantities. This means they shouldn't have an overwhelmingly strong flavor, they should be low in oxalates, and they should grow large quantities of leaves.
Does anyone know of such a plant? I live in Central Texas (hot summer zone 8b), and have heavy clay soil that I have modified in places.
I should add that I hope to be pregnant soon, so edible hibiscus is out, as is anything in the same family unless proven safe for pregnancy. Unfortunately, I think this rules out everything from turk's cap to musk mallow.
