Perennial Peanut: a legume that "fixes" nitrogen from the air into the soil, aiding in fertilization of surrounding plants. The only edible part are the yellow flowers.
After trimming back an area of perennial peanut I wondered how easy it would be to get cuttings to root in water. Three days later, great roots!
The "woodier" and brown stemmed cuttings did not root, but the green stemmed ones did.
