Joi Choi
3273JC Joi Choi Pac Choi (50 days) F-1 hybrid. Why did we offer yet another pac choy, an F-1 hybrid at that, when we already had the wonderful Prize Choy? Because Joi Choi is different. Its leaves are much darker green than Prize Choy's, it is more uniform, a quality valued by market growers, and above all, its basal stem is almost double the thickness of Prize Choy's. Trialer Adam Tomash prefers it to all other varieties because that basal thickness makes Joi so succulent. Suitable both for summer and fall crops, though much less likely to bolt in the fall. Do not disturb the roots when transplanting and space 1' apart.
