Product Details

Is it art or food? Both! 'Romanesco' is not actually a cauliflower, but somewhere between a broccoli and cauliflower, with 5"-6" heads. First noted by Italians in the 16th century, it is now catching the eyes of gourmet chefs. Cooked, 'Romanesco' has a delicious nutty flavor and a texture similar to cauliflower. Easier to grow for fall harvest as a warm spring may delay heads until fall.

When to Sow Outside: Not recommended. 1 to 2 weeks before your average last frost date, or 10 to 12 weeks before your average first fall frost date. In Mild Climates, sow in early fall for winter harvest.

When to Start Inside: RECOMMENDED. 4 to 6 weeks before transplanting outside after your average last frost date, or 12 weeks before your average first fall frost date. In mild climates, sow in fall for harvest in late winter and early spring. Ideal soil temperature for germination is 70°–85°F, cooler (60°F) growing temperatures thereafter.

Seed Spacing: A group of 3 seeds every 24"

Thinning: When 2" tall, thin to 1 every 24"

Growing Info

Harvesting: Harvest heads as soon as they have developed. Head should be firm and solid. Cut at the base where it connects with the stem using a sharp knife. Remove entire plant after harvest since romanesco rarely produces side shoots like true broccoli. Harvest in the morning if possible. If harvested in the heat, dunk in ice water to reduce "field heat" and increase storage time. Allow to drain before storing.

    This was a very successful variety! Despite some rather crazy weather in Zone 8b during the 2024 season - including record highs and lows. Despite all that, this cauliflower not only grew, but thrived. Once harvested it was absolutely delicious. Definitely will be growing again!

    I had a labeling mixup (on my part) and gave away all but one of the romanesco cauliflowers I planted this fall. Luckily, the one I had headed up really well and I got to see the cool fractal pattern that the heads form. Very cool plant and it tasted great too.
