I currently have peas, turnips, kohlrabi, strawberries, and cabbage in my garden (Houston gardens can go all year). Soon I'll plant yellow squash, beans, peppers, and zuchinni. The peas have been producing since October!
For fruits/nuts I have two lime trees, a loquat tree, and two live oaks (acorns).
I also grow purslane, prickly pear, day lilies, cana lilies and assorted other "edible landscape" plants.
I used to do tomatoes but the birds would always eat them.
