Kale (Brassica oleracea var. acephala) is a nutrient-dense leafy green vegetable known as a superfood due to its exceptional vitamin, mineral, and antioxidant content. This cool-season crop originated in the Mediterranean region and has been cultivated for thousands of years. Kale thrives in cooler temperatures and is one of the most cold-hardy vegetables, making it perfect for fall, winter, and early spring gardening.
Kale comes in various types, each offering different textures, flavors, and colors. Here are some of the most popular varieties to grow:
Kale grows best in cool weather with temperatures between 45-75°F (7-24°C). It tolerates light frost which actually improves flavor by converting starches to sugars.
