Organic Broccoli Seeds for Heirloom Garden are organic, non-GMO, and heirloom, delivering a dependable harvest of nutritious broccoli. The seeds can be grown into mature heads or used as sprouts and microgreens. They are suitable for the 2026 growing season. For sowing, we recommend using one of the following: a 12 Cavity Greenhouse, Planter with Humidity Dome, Soil Pods, or Liquid Fertilizer. Sow best in early spring or fall and harvest broccoli regularly. For more germination tips, see the seed guide.

Germination runs 3–10 days at 40–70°F with a depth of 1/2 inch. Plant 2–3 seeds 12–18 inches apart, or per nursery pot or soil pod, in a 9–12 inch planter or box, or garden bed. Time to maturity is about 85 days. Seed prep options include pre-soak, scarification, stratification, or none, and sowing methods include greenhouse, paper towel method, or direct sow. The plants grow as a mounded upright brassica with large heads, reaching 24–30 inches tall and about 24 inches wide in well-draining coconut coir/peat-based soil under full to partial sun.
