Mizuna is a fast-growing Japanese leafy green that reaches harvest in just 18 days, making it one of the quickest salad crops you can grow. This open-pollinated variety of Brassica rapa var. japonica produces feathery, finely cut leaves with a mild flavor that feels fresher and more delicate than most brassicas. The classic mizuna form delivers tender greens ready to harvest at just 3 to 6 inches, though you can let plants grow larger if you prefer. Its speed and gentle taste make it a gateway crop for gardeners new to Asian greens, and its cut-and-come-again nature means a single sowing feeds you repeatedly through the season.

Ready to harvest in just 18 days, this classic mizuna produces finely feathered leaves with a surprisingly mild flavor that feels almost delicate compared to its brassica cousins. The real magic happens after your first cutting: keep harvesting every 5 to 14 days and the plant keeps producing tender new growth, turning a single sowing into weeks of continuous harvest. It thrives in cool-season growing and actually tolerates winter greenhouse cultivation, extending your season far beyond what most greens allow.
Mizuna works beautifully in raw preparations where its delicate, feathery leaves add visual interest and gentle flavor to salads and vegetable platters. The mild character and tender texture make it far less assertive than mustard greens, so it won't overpower other ingredients. Its finely cut leaves also blanch quickly, working well in light stir-fries or as a wilted green alongside rice bowls and noodle dishes.
No timeline data available yet for this variety.
Sow mizuna directly into prepared beds 2 to 3 weeks before your first frost date for fall harvest, or as early as soil is workable in spring. For winter greenhouse production, sow in late summer and early fall to establish plants before cold months arrive.
Begin harvesting when leaves reach 3 to 6 inches in size by cutting above the basal plate with a sharp knife. This cut-and-come-again approach triggers new growth; return to harvest again when plants reach your desired size, typically 5 to 14 days later depending on season and growing conditions. The fast regrowth cycle means a single sowing can produce multiple harvests over several weeks.
