Heat Tolerant Broccoli

Broccoli wants cool weather. Heat pushes ordinary varieties to bolt, and you end up with loose, uneven heads that open into yellow flowers before they size up. The varieties on this page keep tighter heads with a finer, more even bead when temperatures rise, and they hold in the field a few extra days before going past marketable. Amadeus, Bella Verde, Green Magic, Imperial, and Happy Rich are the core of the list, and Green 70 D choi sum fills in for summer greens. Even these won't carry a crop through a Gulf Coast summer. Time plantings to mature in cooler weeks when you can.
