"Nasturtiums are loved for their rich, saturated jewel-toned colors. They are fast and easy to grow and, in fact, do best with a little neglect. There are varieties for almost every gardening purpose: bushy plants for borders and edges, trailing plants for walls and containers and climbers to add dramatic height in a garden. The leaves and flowers are edible, with a peppery tang, and even the seed pods are used as a substitute for capers."
