I have a small sunny space with the rest of the yard being in various densities of shade. My sunny space is crammed with various perennials, shrubs and bulbs that I'm not willing to give up and I interplant with tomatoes, snow peas and kale. I do have one pot of leaf lettuces that got hit with hail earlier this week and is slowly recovering. I also do Chinese/Napa cabbage, bok choy, early radishes, Swiss chard and carrots in pots. As I harvest some of these things, I want to fill in with a few annuals so that I'm not wasting pot space. Then I'll use the pots for more cool season veggies later on in late summer. I put good potting soil and compost in those pots so it's better than my silt-topped clay garden soil. I don't have rabbits here for soime reason - maybe the woods, occasional fox and raccoons scare them off. I sprinkle cayenne pepper around new planted annuals and perennials but that won't help you if you plan on eating your greens. I'd definitely try growing the bitter ones around the bunny-preferred plants. Always a learning experience when trying to keep your food for yourself.
