Edible Pod Radish makes an enlarged, succulent, crunchy pod, in the same fashion as green-beans and snap-peas. The tip of the pod tapers to a fine point, giving it a fanciful resemblance to a rat-tail … a name by which it was formerly found in seed-catalogs etc, but is now not often seen.
Seed-pod vegetables are naturally young, and are grown as part of the reproduction cycle, so are a spare-no-expense plant-function. Tradtionally, green-beans became a staple veggie of common rural families. Typically, the act of picking the immature pods actively stimulates to plant to set more flowers, and pods.
Technically a fruit, like tomatoes and cucumbers, they are treated as a vegetable.
Radishes have a natural tendency to Bolt to Seed. This family of garden plants is anxious to flower and set seed. With the familiar radishes grown for the root, this is a problem. With radishes grown for an edible pod, the bolting-habit works in our favor.
