Choosing the right broccoli variety is key to growing tight, dense heads and enjoying a long harvest season. With over 30 years of gardening experience, I’ve tested dozens of varieties to find those that perform best in a range of climates and garden conditions.

  • Excellent heat tolerance for an early crop.

2. Green Magic

  • Known for heat resistance and bolt delay.

3. Calabrese

Varieties for Longer Harvests​

  • Calabrese and Diplomat excel at producing side shoots after the main head is harvested, extending your eating season by several weeks.
  • Succession planting these varieties further lengthens harvest availability.

My Experience Selecting Broccoli Varieties​


Through decades of hands-on trialing in diverse conditions—from cool coastal valleys to warmer inland gardens—I’ve learned that variety choice dramatically affects harvest size and length. The varieties above have repeatedly delivered tight heads, robust plants, and longer harvests in my garden and those of many other home growers.
