I planted this in August for fall harvest in zone 5. Good germination rate. I've been harvesting the outer leaves but leaving the centers and am still harvesting from the same plants in January, now protected by a caterpillar tunnel. Good flavor, tender enough to eat fresh, although I usually saute or stir fry it.
