The Acephala group is a cultivar group of Brassica oleracea, commonly referred to as kale and collard greens. Unlike cabbage, which forms a compact head, Acephala plants have loose, open leaves, giving them the name acephala,meaning headless in Greek. These leafy greens are valued for their hardiness, rich nutrient content, and versatility in cooking.Acephala plants have large, broad, and sometimes curly leaves that range from bright green to deep purple. Their leaves can be smooth (as seen in collard greens) or ruffled (as in curly kale). Unlike cabbage and Brussels sprouts, these plants do not form dense heads.One of the most remarkable traits of the Acephala group is its ability to withstand cold temperatures. In fact, frost enhances the sweetness of the leaves, making kale and collards a popular crop for late autumn and winter harvests. This makes them a favorite among gardeners in colder climates.
These plants can grow up to 2–3 feet tall.They have a biennial life cycle, meaning they flower in their second year.The leaves can be continuously harvested, allowing for multiple yields throughout the growing season.Curly Kale (Brassica oleracea var. sabellica) – Features tightly curled, frilly leaves and is commonly used in salads, smoothies, and soups.Lacinato Kale (Dinosaur Kale, Tuscan Kale) – Has long, dark green, textured leaves with a slightly sweeter flavor.🌱 Collard Greens (Brassica oleracea var. viridis)Has smooth, broad leaves and a milder taste compared to kale.A staple in Southern U.S. cuisine, often slow-cooked with smoked meats.Features purple-tinged stems and softer leaves with a slightly sweet taste.Ideal for fresh salads or light sautés.
