Napa Cabbage

Brassicaceae

Tall barrel-shaped head of pale tender leaves. DIFFERENT SPECIES than round cabbage (B. rapa). EXTREMELY bolt-prone with NARROW temperature band (50-80°F). Bolts from cold vernalization (<50°F for >1 week in young plants) AND from heat (>75-80°F). Fall planting STRONGLY preferred — decreasing day length and cooling temps are ideal. Spring planting is risky. Less cold-hardy than round cabbage. Stores 1-2 months.
