Cauliflower seeds — from summer white to purple and Romanesco

Cauliflower is the show-off of the brassica bed — dense, creamy curds, and striking purple, green and Romanesco forms, that reward a little care with a real centrepiece crop. Yet another form of Brassica oleracea, it sits within our cabbage family range. New to growing? Our vegetable growing guide covers the basics.

With the right variety you can cut cauliflower across much of the year — the calendar shows when to sow.

Curds for every season

Summer and autumn types are quickest; hardy winter and spring varieties stand the cold to crop in the lean months. Romanesco adds lime-green spirals, and there are vivid purple and orange curds too — all close cousins of the leafy brassicas and broccoli.

Growing cauliflower from seed

Cauliflower likes rich, firm, limed soil and, above all, no check to growth — steady water and feeding give the best curds. Sow in modules, transplant carefully, net against pests (see our pest control guide), and shade summer curds from strong sun to keep them white.

Growing more brassicas? Here's where to look next.

Frequently Asked Questions

Is cauliflower hard to grow?
It rewards steady, uninterrupted growth — rich, firm soil and reliable watering give the best curds.

What types are there?
Summer, autumn, winter and spring varieties, plus Romanesco and coloured purple and orange curds.

Why has my curd discoloured?
Sun and age can spot or yellow it — shade summer curds with a few leaves.

When do I sow it?
Depending on the type, for cutting across much of the year — see the calendar.

How do I protect it from pests?
Net against caterpillars and pigeons as for other brassicas.
