Yes! And really, what smells more yummy than mustard greens? It's one of those things that smell almost better than they tasteMustard greens are good stir fried with some bacon. In the old days before fats weren't good for you cooks mother would fry the bacon and use the hot grease to stir fry the mustard. Mustard is also good cooked in a pot of turnip greens. It adds a good flavor to the greens. i have mustard, kale and turnips in the garden now. Most of that will last until about Christmas. Kale is the most cold hardy and it will last throught the winter. Collards will last almost year round. Just break off the younger tender leaves and let the plants grow. By late spring the stalks will be 3 feet tall and still producing for you and your chickens.
