Broccoli, Calabrese

Broccoli, Calabrese - Brassica oleracea (Italica Group)

Calabrese broccoli is a classic Italian heirloom known for its large, central green heads, excellent side shoot production, and superior flavor. Named after the Calabria region of southern Italy, this variety was introduced to the U.S. by Italian immigrants in the 1880s and remains a staple in home gardens for its reliable yields, cool-season hardiness, and rich, nutty-sweet taste.

Unlike modern hybrids bred for uniformity and single harvests, Calabrese produces one main head followed by multiple smaller side shoots over several weeks, extending the harvest period and making it ideal for home and small-scale growers who prefer multiple pickings over time.

Key Characteristics

• Classic Heirloom Flavor and Productivity
  Calabrese broccoli is prized for its rich, slightly nutty flavor and tender texture. The central head grows 4-8 inches across, and side shoots continue producing after the main head is harvested.

• Extended Harvest Window
  After the first cut, the plant sends out numerous side shoots, allowing for continued harvests for several weeks. This makes it a valuable crop for staggered fresh eating, freezing, or light processing.

• Thrives in Cool Weather and Early Spring/Fall Gardens
  Well-suited for spring and fall planting in temperate climates, Calabrese tolerates light frost and performs best in cool weather. Ideal for succession planting and season extension systems.

• Excellent in Companion Plantings and Garden Rotations
  Works well with herbs like dill and chamomile (which repel pests), and grows harmoniously with alliums and leafy greens. Like all brassicas, it benefits from crop rotation to avoid soil-borne diseases.

• Adaptable to Raised Beds, Market Gardens, and Kitchen Plots
  Calabrese's open-pollinated genetics make it a great choice for home seed saving, and its vigorous growth fits well in organic systems, no-till beds, and small garden plots.
