One Kilo Slow Bolt has a delicate flavor, a soft texture in between that of lettuce and regular cabbage, and tight heads have a creamy yellow interior. Also called Napa Cabbage. Grows with ease in fall, and can be sown in spring if care is taken to protect young plants from temperatures of 50 degrees F or below, which may cause plants to bolt. Grows best at 60-65 degrees F.
