Believed to be of very ancient origin, the spoon-shaped, dark green, evenly spaced leaves make tatsoi a plant worthy to be grown for its decorative value alone! More nutritious (high calcium and vitamin content) and more flavorful (slightly mustard-like) than traditional bok choy; many consider it a superior flavor, and it is prized for its smooth texture. Very cold tolerant; withstands temperatures down to 15°F. Tatsoi can be harvested even when there is snow on the ground!
