‘One Kilo Slow Bolt’ cabbage has a soft texture between that of lettuce and regular cabbage and tight heads with a cream-yellow interior. Grows with ease in the fall and can be sown in the spring as long as they are protected against temperatures of 50°F or below which may cause plants to bolt. Grows best between 60°-65°F. Botanical Interests’® One Kilo Slow Bolt Napa Cabbage Seeds have been verified by The Non-GMO Project.
One packet sows up to 43 feet.
