Who has a few veggies tucked in their flower beds? My mom always sneaks a container with a tomato plant into her side yard. She grows a bush variety so it doesn't take up too much space. It gets watered by the sprinklers automatically so she doesn't have to worry about it.
I've got a pepper growing in a side plot too. You don't notice it's a veggie until the peppers start turning colors. I've also got culinary sage growing, it has beautiful blue flowers in the spring too.
Who else is 'breaking the rules'? What are you growing?
