Both vegetables are crucifies, related to cabbage and broccoli. The most common form of Chinese cabbage has a cylindrical tight head 4 inches thick and up to 18 inches long. Outer leaves are light green with a white midrib; inner leaves are creamy yellow. Chinese mustard has a loose head and rosette of dark green leaves which are oblong or oval with shiny dark green blades and thick white petioles.
Both are cool season crops. A spring crop can be grown from transplants set out in early spring. For the fall crop, sow Chinese cabbage seed 60 to 80 days before frost date and 50 to 60 days before frost for Chinese mustard. Well-drained, fertile, moist soil promotes the desirable rapid tender growth.

Harvest greens 5 to 6 weeks after sowing. As with most greens crops, young succulent leaves are preferred for eating. Greens are tied in bunches and sold in cartons by the bunch or by the pound. Keep amaranth greens refrigerated or iced during shipment or storage.
