Thomas Jefferson's vegetable garden commonly included various Kales such as German, Scotch, Delaware, Malta, and Russian types. Red Russian Kale, also called Ragged Jack, is an extremely cold-hardy variety that originated in Russia and was introduced to Canada around 1885. The highly attractive blue-green leaves have purple veins and stems, turn reddish-purple in cold weather, and have lightly-frilled edges.
Direct sow seeds 1-2 weeks before last frost date in spring, and 10-12 weeks before first frost in fall in well-drained, fertile soil. Kale is best grown as a spring, fall, or winter crop, as cool temperatures and frosts enhance the flavor. Approximately 100 seeds per packet.
