Collards are nutritionally dense dark leafy greens that grow so easily in most gardens! These easy to grow greens are a superfood too often underrated in the kitchen. We love collards greens in our stir-fries, soups, salads, and any dish. Use Collards interchangeably with kale. Collards enjoy cool temperatures but can handle warm temperatures and still thrive—mulch around plants to retain moisture. Collard greens can become perennials in mild climates like that of San Diego. Grow collards in your garden for a heavy and constant yield of dark leafy greens.
