Electric purple stems contrast sharply on this very attractive plant with dark green foliage to make your salad really pop! This mild, tender, delicious mustard green is often eaten raw in salads or stir fried. The greens are ideal when harvested just before the yellow flowers bloom, when plants are between 10-12 inches tall. Sow this traditional Cantonese vegetable in early spring and early fall for a tender treat that quickly matures within 35-40 days. Short day length will cause the stems to stretch. Flavor is similar to broccoli raab, just a bit sweeter.
