Mustard greens seeds — fast, peppery leaves for salad and stir-fry

Mustard greens bring real warmth to the salad bowl and the wok — quick-growing leaves with a hot, mustardy bite, from frilly green types to dramatic red-purple ones. Botanically they are Brassica juncea, and they sit among our Asian greens within the wider vegetable range. New to growing your own leaves? Our vegetable growing guide covers the basics.

Sown little and often, mustards crop in weeks and are at their best in the cooler months — the calendar shows the windows.

Choosing the right type

Mild green mustards like Green in the Snow are good all-rounders; frilly types such as Golden Streaks add texture to salads; and red mustards like Red Giant bring both colour and a fierce kick. Pick milder kinds for raw baby leaves and the hotter ones for cooking, where the heat softens.

Growing mustard greens from seed

Mustards are about as easy as leaves get. Sow direct little and often, grow densely for cut-and-come-again baby leaves or thin for larger plants, and harvest from just a few weeks old. They thrive in the cool of spring and autumn; in summer heat and long days they bolt fast and turn fiercely hot, so cooler sowings give the sweetest leaves.

As hardy brassicas, many will crop well into autumn and stand light frosts, especially under a cloche.

How hot are mustard greens?
It depends on the type and how they are grown. Young leaves grown cool are gently peppery, while mature leaves and hot-weather growth can be fiercely mustardy. Cooking mellows the heat. When is the best time to sow mustard greens?
Spring and especially autumn, when cool conditions keep the leaves milder and slower to bolt. Summer sowings tend to run to flower quickly. Can I use mustard greens raw?
Yes — pick them young as baby leaves for a peppery lift in salads, or grow them on and stir-fry, steam or braise the larger leaves. Are mustard greens the same as the plant used for mustard seed?
They belong to the same species, Brassica juncea. Some forms are grown mainly for their leaves and others for the seed used to make mustard.
