I just planted a group of 5 this year in my edible backyard forest but thought you guys here at BYC will like this plant--it's a super cold and drought tolerant edible legume that is also... a tree and perennial. I hear it's bland as far as the peapods go (but, quite honestly, we're so used to these super sweet peas that we forget the sugar content is higher than the stuff in the wild) but many people in the eastern hemisphere supposedly plant it as plant for their chickens (in their runs) because well, a tree is hardier than grass/herbaceous plants, and because they produce large amounts of small beans that fall to the ground and the chickens gobble up. Pros: Nitrogen fixer since it's a legume. Flowers and young peapods edible fresh for both people and poultry. Dried "Peas" (which look more like beans) can be eaten like lentils or any other dried beans, or left on the ground for chickens/poultry to eat. Perennial (because it's a tree, not a vine) Drought and cold tolerant (down to USDA hardiness zone 2--yep... would take a lot of cold to kill this thing) Used as a windbreak/hedge, probably also good cover against aerial predators. Relatively fast growing. High protein content (36%) Cons: Peapods are supposedly bland--but hey, zombie apocalypse, I'm not going to be complaining. Can self seed so may become invasive? Although probably not if all the chickens peck the seeds to death. These are one of the plants I think that would be great for chicken landscaping and not get scratched to death once it's large enough.
