Green River (F1) Asian Green Seed

Item #HSC-GRN-014-PKT

An upright komatsuna for bunches and baby leaf.

Green River is a slow-bolting komatsuna with dark green leaves on long, slim stems. Baby leaves hold their quality for a long time, so the picking window is wide.

Komatsuna is close to tatsoi but denser and less juicy. Steam it with soy sauce, add it to stir-fries and soups, braise it, or use young leaves in salads.

About 21 days to baby leaf and 35 days to full size, from sowing. F1 hybrid.

Growing Information

Scientific name

Brassica rapa var. perviridis

Season

Sow from early spring into midsummer. In mild areas, or in a high tunnel for overwintering, sowing can continue into late fall.

Days to maturity

Counted from the direct-sowing date.

Direct sowing

For full-size bunches, sow about 15 seeds per foot (10–12 per foot for Green 70 D Improved), 1/4" deep, in rows 12–18" apart. Most of these greens need no thinning; any that do say so in the description.

Seeding rate

For bunching at that spacing: roughly 1 oz. per 830 ft. and 1 lb. per 13,000 ft.

Succession

A fresh sowing every 7–10 days keeps budding, cutting and heading types coming without a gap.

Insect pests

Floating row cover laid at sowing is the best defense against flea beetles.

Harvest

Flowering-shoot types such as choi sum and kailaan are picked when the buds are full and just a few have opened, and they regrow for several cuttings. Heading and leafy types such as komatsuna and Chinese cabbage are cut once, anywhere from medium to full size.

Packet

250 seeds.

Seeds per lb.

About 134,900 on average.
