Vegetable gardens, rewarding as they are, often seem regimented and dull, at least to me. They're less utilitarian and more delightfully complex when they include flowers as well. You can add edible flowers like nasturtiums and borage or go for some of the plants that like the same rich soil such as dahlias, gladiolus and pansies. Play with leaf textures, color combinations and swirls rather than rows. Why should anything useful be boring as well?
