Mustard seeds — peppery leaves with a kick

Mustard greens add a real peppery punch to salads and stir-fries — fast, easy leaves in green, red and frilly forms that bring heat to the cool-season garden. They sit among our Asian greens and leafy brassicas within the vegetable seed range. New to growing? Our vegetable growing guide covers the basics.

Mustard is quick and best in cooler weather — the calendar shows when to sow.

Salad leaf and more

Cut as baby leaves, mustard adds bite to a salad bowl and is one of our quickest fast-growing vegetables; grown on, the larger leaves are wonderful wilted or stir-fried. Some types are also grown as a green manure to enrich the soil.

Growing mustard from seed

Sow direct in the cooler halves of the year, keeping the soil moist so the leaves stay tender and mild rather than fiery. Pick young and often, and protect seedlings from flea beetle.

Love peppery leaves? Here's where to look next.
