About Shanghai Green
45 days. Baby-type with light green stems and large spoon-shaped leaves. Extra-tender. Can be planted as a spring or fall crop.
About Bok Choi
One of the oldest of the Asian greens. Stalks are mild and crunchy while the leaves are pleasantly tangy; each has different cooking times, so it's like getting two vegetables for the price of one. A cool-weather crop.
