Collards, Tree 1-Ga
Tree collards are a perennial vegetable related to collard greens. They can get over eight feet in height and will grow year after year. They were introduced to California, probably during the latter half of the eighteenth century, from the island of Jersey in the English Channel where they were grown to feed cattle. They are best for eating in the cooler months and are super nutritious--very high in calcium! The sweetest-tasting leaves are the ones harvested after a light frost.
