Every year I let a few radishes go to seed. The root turns as big as a turnip, the plant grows about two feet high and becomes covered with small white flowers. The flowers fall and pods form. This happens continually through the summer. The pods are crunchy and delicious. Many years ago I read somewhere that radish plants were originally grown, not for the root, but the pods. I have offered the pods to many people including my father, who was an avid gardener. The reaction is always the same; they are never sure if they are indeed edible, but once they try them they like them. The pods taste like radishes, but milder. You can get a lot of eating off one or two plants.
