Ching-Chiang Pac Choi
Brassica rapa, Chinensis Group 40 days. This early, dwarf pac choi is a real performer in the home garden. Only 14 inches tall, it is sturdier and stockier than most dwarf pac choi. The smooth medium green leaves and thick petioles have a wonderfully mild flavor, are tender, and have very few strings. Ching-Chiang is tolerant of heat, rain, cold, and dampness, making it a great choice for late summer and fall planting.
