White Ice Mustard is a dual-purpose Brassica that thrives across a wide hardiness range (zones 2-10), delivering both a culinary punch and soil-building benefits. This non-GMO organic variety matures in 70-79 days, reaching 18-24 inches tall with an upright growth habit that fits neatly into any garden bed. What makes it special is its versatility: grow it as a microgreen for those distinctive sweet and spicy leaves, harvest the mature foliage for cooking, or save the seeds to grind into homemade mustard.

White Ice Mustard bridges multiple gardening goals in a single seed packet. Fresh from the garden, the leaves deliver a unique balance of mild sweetness layered with peppery heat that intensifies as the plant matures. Beyond the kitchen, this variety pulls its weight as a cover crop, actively fixing nitrogen back into soil and improving fertility for whatever comes next in your rotation. It's equally at home in a microgreen tray or a full-sized garden row, making it one of the most adaptable mustards for different growing scales.
White Ice Mustard serves multiple purposes in the kitchen and garden. The young leaves work beautifully as a peppery microgreen, adding texture and bite to salads and sandwiches. At full maturity, the larger foliage can be cooked down like other brassica greens, mellowing slightly when heat is applied. The seeds themselves are the real prize for the adventurous cook: harvest and dry them, then grind into a sharp, traditional mustard paste. Beyond culinary applications, this variety earns its place in vegetable gardens as a cover crop that enriches soil with nitrogen, improving conditions for subsequent plantings.

Direct sow White Ice Mustard seeds into the garden during cool-season windows: early spring (as soon as soil can be worked) or late summer for a fall harvest. Sow seeds thinly and thin seedlings to 6 inches apart once they have true leaves.
For microgreens, harvest when the first true leaves appear (typically 7-10 days after sprouting) by cutting just above the soil line. For full-size leaves, begin harvesting outer leaves once the plant reaches 6-8 inches tall, allowing the center to continue growing. Mature plants reach full harvest readiness around 70-79 days. If saving seeds, allow select plants to bolt and flower, then collect dried seed pods in late summer and thresh to extract the seeds.
