Direct Answer

When growing broccoli in Zone 7b, selecting the right variety is crucial for success. Broccoli is a cool-season crop, which means it thrives in the cooler temperatures of spring or fall. In Zone 7b, the ideal time to plant broccoli is early in the season, before the heat sets in, or late in the season, as the temperatures cool down. This allows the plants to mature before the heat becomes too intense, causing them to bolt or become stressed. The key to success lies in choosing varieties that can mature quickly, tolerate heat, and resist disease, making them perfect for Zone 7b's cool-season planting windows.
