Grow flavorful, reliable broccoli with Green Sprouting Calabrese seeds—an excellent choice for fresh cooking, steaming, and preserving.

Originally from Italy, this variety is known for its rich flavor, strong performance in cooler weather, and dependable production. Calabrese broccoli forms firm central heads and can continue producing smaller side shoots after the main harvest, making it a practical addition to any garden.

These seeds are 100% heirloom, non-GMO, and open-pollinated, allowing you to grow, harvest, and replant your crop season after season as part of a self-sufficient garden.

Planting Instructions

Broccoli is a cool-season crop that performs best with consistent conditions and proper spacing:

  • Indoor Start: Begin seeds indoors 5–7 weeks before your last expected frost
  • Planting Depth: Sow seeds 1/4 inch deep
  • Spacing: Space plants about 18 inches apart
  • Sunlight: Full sun required for best growth
  • Soil Prep: Loosen soil 12–15 inches deep and enrich with compost if possible
  • Moisture: Keep soil consistently moist, especially during early growth
  • Transplanting: Move outdoors once seedlings are established and weather is stable

Harvesting Instructions

Proper timing will give you the best flavor and continued production:

  • Time to Harvest: Approximately 90 days from planting
  • Main Head: Harvest when the central head is firm, tight, and fully formed
  • Cutting Method: Cut the main head at an angle, leaving the plant intact
  • Continued Growth: Side shoots will continue to develop after the main harvest
  • Avoid Overmaturity: Harvest before buds begin to open or yellow flowers appear

Saving Seeds

Saving seeds from broccoli requires planning, as it is a biennial plant that produces seeds in its second growing season.

Select strong, healthy plants and allow them to overwinter if your climate allows, or replant them the following season for seed production. Once the plant flowers and forms seed pods, allow them to fully mature and dry on the plant.

After harvesting, dry the pods completely before removing and storing seeds. To maintain seed quality, avoid cross-pollination with other brassicas such as cabbage or cauliflower.
