The Story
Costata Romanesco' delivers a manageable harvest of high-quality, fluted fruits with complex flavor and firm texture. The striped and mottled skin stays tender even to 18", though in Italy they are picked at 4"-5" with the blossoms still attached. Large production of male blossoms for stuffing.
When to Sow Outside: RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is 70°–85°F.
When to Start Inside: Not recommended except in very short growing seasons, 2 to 4 weeks before transplanting. Roots are sensitive to disturbance; sow in biodegradable pots that can be planted directly into the ground. Transplant when soil temperature is at least 60°F.
Days to Emerge: 5–10 days
Seed Depth: ½"–1"
Seed Spacing: 2–3 seeds per mound
Row Spacing: 3'–4'
Thinning: When 3 leaves, thin to 1 plant per mound
