Great veggie patch! I wish we had enough room for a vegetable ptach... we did use to have a bean and veggie area... but that has given room for other more ornamental plants... that said, we still have herbs, a grape vine, blackberries and maybe a cherry tree... possibly a apple tree in the future... wel'll see.... but we don't have the crazy amount of sun that you have, on the other hand... we have too much water!
You know, when I had a very small patch of soil, I still grew edibles like tomatoes, lettuce and chard between the ornamentals. Some ornamentals are great companion plants e.g. Rose's and strawberries. The Husband was amazed at what I grew in a patch about 5m square. It's only since we've been in McGregor and bought the adjacent plot that we've really had space. Actually, I should find some photos of our tiny veggie patch in Cape Town
