3cm between plants · 20cm between rows

Sow thinly in rows and thin to this spacing once seedlings emerge.

the varieties

Varieties worth growing

Long and elegant, red-shouldered with a white tip, and mild enough to eat like sweets straight from the soil. As pretty in the hand as it is on the plate.

in the kitchen

Radishes with butter and salt

Good butter, flaky sea salt, and the freshest radishes you can pull — dip and eat. The French have done it this way for generations, and they're right to.

Round, red and ready in about four weeks — quicker than almost anything you can grow. A lovely one to sow with children, who get to pull something of their own before their patience quite runs out.

in the kitchen

Quick pickled radishes

Slice paper-thin, toss into a jar with rice vinegar, a pinch of sugar, and a star anise. Ready in an hour. Incredible on tacos, noodles, or anything that needs a pink crunch.

Plain green on the outside, then you slice it open to a vivid magenta starburst within. Mild and faintly peppery, and the sort of thing that quietly stops a table mid-conversation.

Watermelon radish carpaccio

Slice razor-thin on a mandoline, fan out on a white plate, drizzle with yuzu or lemon juice, good olive oil, and a scatter of black sesame seeds. Looks like stained glass.

Sparkler

common

Red on top, white below, quick to grow and gently mild — a cheerful little radish for the front of a border or a window box, and a kind one to grow with children.

in the kitchen

Radish top pesto

Don't waste the leaves. Blitz radish tops with garlic, parmesan, pine nuts and olive oil into a peppery, fresh pesto — the best of the radish is often the part we forget.
