Bopak Pac Choi

Bopak Pac Choi

OV589

40 days. The first of its kind in many ways, Bopak produces picture-perfect heads of baby pac choi. Allowed to grow, it will continue to rapidly develop into a compact, upright, full-sized plant with 8 inch tall heads that measure 4 inches across. The tender, fleshy leaves are crisp and flavorful with wide, glossy ivory stems topped with deep green. Bopak is remarkably bolt resistant and is the first pac choi to earn an AAS award. HR: PB.
