Heat Tolerant Cauliflower

Cauliflower is fussy about heat. In a warm spell, ordinary varieties go ricey, turn yellow or purple, or open into loose, fuzzy curds before harvest. The hybrids on this page keep a smooth, firm, bright head through warmer stretches than standard types. Look at Bishop, Clementine, EarliSnow, Flame Star, Fujiyama, and Paxton, all hybrids, with one organic option and one carrying clubroot resistance. Tie or break leaves over white heads to shade them as they size up. As with any cool-season crop, the heat limits are real, so in the Southeast and Southwest aim for fall and winter harvests.
