Nasturtiums are one of my favorite flowers because of their ease, versatility and flavor, and of course their beauty. These little wonders require very little attention to thrive in your garden. Just give them some soil, water and room to grow and they’ll be happy campers. Both nasturtium flowers and leaves are edible as long as you don’t use pesticides. They give a peppery punch similar to watercress in salads and pasta dishes, and the flowers add a hit of color and flavor. Nasturtium seeds are edible as well when they are young and green and have been likened to capers when pickled. They even offer their fare share of Vitamin C.
