Romanesco is a stunning brassica with a lime-green head composed of fractal-patterned spiraling florets. It has a nuttier, milder flavor than cauliflower.

Fisher County, Texas is in USDA Zone 8a. The average last spring frost is March 25 and the first fall frost is November 15, giving you a growing season of approximately 235 days.

At an elevation of 1,474 feet, Fisher County receives approximately 59.6 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 97°F, so Romanesco may need afternoon shade and extra watering during peak heat.

Romanesco Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Romanesco needs ~1,991 GDD — county provides 5,346 GDD Excellent fit
