Why would vegetables not qualify for suitable live plant material. Anyone seen squash blossoms...they're beautiful. And all that green foliage interspersed with beautiful read tomatoes, the changing colors of peppers, dark purple eggplant, crooknecks, lemon cucumbers, cauliflower, broccoli, the beauty if vines, tall cornstalks, pole beans & peas winding up a tepee, the lacy green of tomato leaves. I think vegetable gardens are just as beautiful as perennials.
