Serifon Mustard is a cold-hardy Chinese mustard that thrives in cool seasons, delivering fresh greens in as little as 30 to 39 days. This upright, bunching variety grows 18 to 24 inches tall with dark green, beautifully serrated leaves that create an ornamental appeal in the garden. Hardy from zones 2 to 10, it's an heirloom, non-GMO annual that earns its reputation as a 'Green in Snow' mustard, persisting through deep winter cold when most greens have given up. Plant it in late summer or early fall and you'll have peppery, raw greens through the coldest months.

Serifon's cold tolerance is genuinely exceptional; it doesn't just survive winter, it thrives in it, making it one of the finest options for gardeners seeking fresh greens when snow is on the ground. The dark green, heavily serrated foliage has an upright, almost sculptural quality that looks as good as it tastes. At 30 to 39 days to maturity, it delivers faster than many mustard varieties, and the raw leaves pack a strong, peppery punch that commands respect in the kitchen.
Serifon's raw leaves deliver a sharp, peppery bite that works beautifully in salads, stir-fries, and as a bold green for sandwiches and grain bowls. The strong flavor makes it particularly suited to Asian cuisine, where it can be used fresh in spring rolls or lightly cooked as a side green. Its cold-season availability makes it invaluable for winter salad gardeners who want peppery greens when lettuce isn't an option.
No timeline data available yet for this variety.
Sow Serifon seeds directly into the garden in late summer or early fall for winter harvest. This is the preferred method for this variety, which matures quickly and prefers to grow without transplanting disturbance.
Begin harvesting outer leaves once the plant reaches a usable size, typically within 30 to 39 days of sowing. You can pick individual leaves or harvest the entire plant by cutting it at soil level. The dark green, serrated leaves are your visual cue for readiness; they should be firm and vibrant. Harvest in the morning for maximum crispness, and continue picking outer leaves to encourage new growth from the center.

“Also known as Suehlihung Mustard, this heirloom variety carries the genetics of Brassica juncea var. capitata, a Chinese mustard lineage with deep roots in Asian agriculture. Its alternative common name, Green in Snow mustard, hints at its remarkable cold resilience and its traditional role in winter gardens across temperate regions. The variety represents generations of selection for cold hardiness and the ability to produce tender greens even as temperatures plummet.”
