Joi Choi
3273JC Joi Choi Pac Choy (50 days) F-1 hybrid. Joi’s leaves are much darker green than Prize Choy’s and its basal stem is almost double the thickness, making it so succulent that trialer Adam Tomash prefers it to all other varieties. Market growers will appreciate its uniformity. 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.
