Brassica oleracea var. acephalla. Blue curled scotch kale is a large-leaf kale variety that produces many leaves per plant, dark green in color, and tightly crinkled. The leaves are sweet, tender, and crunchy especially when harvested after exposure to cool frosty weather. It is often seen as a garnish, however; this kale is a superfood! Loaded with antioxidants, vitamins, and minerals, this variety is perfect for juicing. It is also amazing in smoothies, salads, microgreens, and even kale chips.
