Green River Asian is an F1 hybrid komatsuna bred for upright, refined growth and quick maturity. Ready to harvest in just 21 days, this compact Asian green thrives in cool-season gardens from early spring through fall, and even into winter in mild climates or protected structures. Its tight, bunching habit makes it excellent for both full-size harvests and repeated baby leaf picking, delivering tender greens when most other crops are still establishing.

This komatsuna stands apart for its blazing speed and architectural elegance. At just 21 days to first harvest, Green River Asian moves from seed to table faster than almost any green in the garden, yet it maintains the refined upright form that sets it apart from sprawling Asian greens. The compact growth habit means you can tuck it into tight spaces while still getting generous yields, and its cold tolerance lets you extend the season well into late fall or even overwinter it in a cold frame.
Green River Asian shines as a tender bunching green for fresh markets and home harvest. Its rapid maturity and baby leaf capabilities make it ideal for repeated cutting, where you can harvest outer leaves while the plant continues to produce. It's equally at home as a full-size head harvest when mature, offering flexibility depending on how you want to use it. The refined, upright leaves work beautifully raw in salads or lightly wilted in stir-fries and Asian dishes.

Sow seeds directly into garden soil from early spring through midsummer. In mild climates, you can also sow into late fall for winter harvest. For overwintering in a high tunnel or other protected structure, sow when temperatures begin to cool in late summer or early fall.
Green River Asian reaches maturity in just 21 days from sowing. For baby leaf harvests, begin cutting outer leaves once the plant has several true leaves, and continue harvesting as needed for continued production. For full-size heads, wait until the plant reaches your preferred size, then cut at the base. Multiple harvests are possible if you take leaves selectively, or harvest the entire head for a single, larger picking.
