Old Cobblers Farm™ Wicked Tuff Turf Siberian Kale (Cold-Hardy Brassica Variety)

Grow resilient, nutrient-rich Siberian Kale! This cold-hardy brassica variety thrives in cooler climates, offers tender, frilly leaves, and provides a long harvest season. Perfect for fall, winter, and early spring gardens.

Siberian Kale (Brassica napus, cold-hardy variety) is one of the most resilient and nutritious leafy greens you can grow. Renowned for its frost tolerance and ability to thrive in cooler climates, this kale variety is a reliable crop for fall and winter gardens. Its tender, frilly leaves are packed with vitamins A, C, and K, plus essential minerals like calcium and iron—making it both a gardener’s and a chef’s favorite.

Unlike heat-sensitive greens, Siberian Kale maintains excellent flavor and texture even in cold weather. In fact, light frosts enhance its natural sweetness. With a fast germination time (5–10 days) and full maturity in 50–70 days, it’s an excellent choice for continuous harvests throughout the cool season. Whether enjoyed fresh in salads, blended into smoothies, or cooked into hearty meals, Siberian Kale delivers a consistent yield of flavorful, nutrient-dense leaves.

Perfect for both beginner and experienced gardeners, these non-GMO seeds are carefully selected for purity, high germination rates, and strong performance in diverse soils.
