Choy Sum Green 70 D Improved

Choy Sum Green 70 D Improved is much more tolerant of warmer weather than past versions. Choy sums are among the most popular vegetables in Hong Kong, Taiwan, and China. The stems are a vibrant bright green, very sweet and tender, and are usually harvested just before, or as the first few buds are opening. The stems regrow for cut-and-come-again harvest. Excellent in stir-fries, steamed, or in soups.

Choy Sum is similar to Gai Lan (Chinese Broccoli)

Sow: early spring through midsummer. May be sown into late Autumn in temperate climates or when overwintering in a high tunnel or other protected structure. (Likely most of the year in Tasmania outside mid winter outside)

Spacing: For full-size bunching: sow 15 seeds/30 cm, rows 30-45cm apart.
