Answer: The secret to companion planting is to choose annuals and perennials with the same cultural requirements as your veggies. Since you're growing heat and sunshine-loving veggies, choose plants with similar needs: zinnias, saxifage, asters, Rockcress, Sea Thrift, ice plant, sedum, thyme and mint. Marigolds, sage, lavender, and dahlias would grow well with your veggies, too. Try them all and see which ones you like best.
