Broccoli - Romanesco

Brassica oleracea

Romanesco broccoli is recognised by its unique geometric shape and vibrant green colour. This Italian variety is not only grown for its visual appeal, but for its mild and nutty flavour, which sets it apart from traditional broccoli and cauliflower.

About Romanesco Broccoli: Romanesco plants produce a central head followed by multiple side shoots, allowing for prolonged harvesting. The plants typically grow up to 80 cm tall and feature dense, spiral florets that exhibit a natural fractal pattern. This variety is favoured for its crunchy texture and consistency in flavour, offering a sweeter and less bitter taste than common broccoli.

Growing In Australia: Romanesco broccoli performs best in cooler regions of Australia but can be grown in other areas with some shade during peak heat. It prefers fertile, well-drained soil and needs protection from common brassica pests like aphids and caterpillars. 

Benefits and Uses: Nutritionally, Romanesco is rich in vitamins C and K, dietary fibre, and antioxidants. It is suitable for steaming, roasting, or raw thanks to its firm texture. Its gentle flavour makes it a great ingredient in dishes where a subtler taste of broccoli is desired.

Planting and Care Tips: For best growth, start Romanesco broccoli seeds indoors or sow directly outdoors in late summer for an autumn harvest. Plant seeds about 6mm deep, spacing plants 30cm apart. Ensure the plants receive steady water, particularly as they establish and begin to develop heads. Full sunlight is necessary, though light afternoon shade can be beneficial in hot climates. Feed regularly with a nitrogen-rich fertilizer to promote healthy growth and head formation.
