What is the growth habit and size of the cauliflower?

Cauliflower typically has an upright growth habit, with broad, green leaves that form a rosette around a central head. The plant generally reaches a height of 18 to 24 inches (45 to 60 cm) and spreads about 18 to 24 inches (45 to 60 cm) wide. The central flower head, or curd, is usually 6 to 8 inches (15 to 20 cm) in diameter when mature. Cauliflower thrives in cooler temperatures and requires full sun for optimal growth.
