We all know the type: the overachiever. They're a whiz at math and write poetry in their free time. They can name all the states in Mexico, do embroidery, and play the trumpet—oh, and they can cook, too. Well, nasturtiums are the overachievers of the flower world. Tender lily-pad leaves grow on prolific vines, and their resplendent flowers are painted with a whole spectrum of hues. Plus, they're edible! The flowers, leaves, and even immature seeds are crisp, spicy, and sweet. Give these pretty and prodigious plants full to partial sun and adequate water and watch them flaunt.
