Dark green, large spoon-shaped leaves with wide, light green midribs and mild flavor. Shanghai Green forms densely packed, vase-like heads. Plants can be spaced closely for baby choy, which is in demand with chefs for its tenderness and mild flavor.

Most Asian Greens are moderately hardy annuals and can be sown from early spring through midsummer. Asian greens are in the same family as mustards but tend to have a mild flavor and lack the spiciness that many mustards are known for. Asian greens include an assortment of species that can be grown for baby leaf or full size crops.
