Red Mizuna
Brassica rapa var. nipposinica
vegetableRed Mizuna is a Japanese mustard green with deeply feathered, finely divided leaves that range from deep burgundy to red-purple in color, creating an elegant, delicate appearance. It has a mild, slightly peppery flavor that is less intense than other mustard greens, making it popular for salads and stir-fries. The plant is fast-growing, cold-hardy, and ornamental enough for decorative garden borders.

Seedling
1-2 weeksTiny seed leaves emerge within 5-10 days; first true leaves are feathery and delicate with red coloration beginning to show
Keep soil consistently moist; provide bright light; thin seedlings to proper spacing once first true leaves appear
Vegetative Growth
2-3 weeksPlant develops multiple deeply divided, feathery leaves with increasingly vibrant red-purple coloration; leaf structure becomes more complex and ornamental
Maintain consistent moisture and fertility; apply balanced fertilizer every 2-3 weeks; mulch around plants to retain moisture and regulate soil temperature
Pre-Harvest Maturity
1-2 weeksLeaves reach full size with complete feathering and deep red coloration; plant achieves full ornamental and culinary potential without bolting
Begin selective harvesting of outer leaves; increase watering if temperatures rise; provide afternoon shade if temperatures exceed 75°F
Harvest/Extended Use
2-4 weeksPlant continues producing tender new leaves at center; outer leaves remain harvestable; color and texture remain excellent
Harvest regularly to encourage continued growth and prevent flowering; pinch off any flower buds that form; continue consistent watering
Senescence/Bolting
Variable, triggered by heat or day lengthPlant eventually produces flower stalks and may become tough and bitter, especially in heat or long days
Once bolting begins, harvest quality declines; consider succession planting for continuous harvest; pull spent plants

Harvest Tips
Mizuna is ready for harvest in 30-50 days and can be harvested in two ways: cut the entire plant 1 inch above the soil line for a full harvest, or use a 'cut-and-come-again' method by removing outer leaves as needed, leaving the center to continue growing. Young leaves (20-30 days) are most tender and mild; harvest in early morning for best flavor and texture. Can be harvested at multiple stages from microgreen to full maturity.
Fun Facts
- 🌱 Red Mizuna is a relatively recent ornamental variety selection, with deep red pigmentation intensified by cooler temperatures and selective breeding—the same anthocyanin compounds that create its color also provide antioxidant benefits.
- 🌱 In Japan, mizuna has been cultivated for over 1,000 years and is traditionally used in Kyoto cuisine; 'mizuna' literally means 'water greens' in Japanese, referring to its preference for moist growing conditions.
- 🌱 Red Mizuna can be harvested continuously for up to 8 weeks with proper care, making it one of the most productive leafy greens per square foot, especially when using the cut-and-come-again method.
