What is red mizuna (Brassica rapa var. nipposinica ‘Red Mizuna’), what is it good for and how do you grow it at home?
Red mizuna is a Japanese leafy salad green, a close relative of green mizuna, but with dark red to purple feathery leaves. As well as being decorative, it has a mildly peppery flavour reminiscent of a blend of rocket and mustard greens. It is often used in salads, stir-fries and as a plate garnish thanks to its striking colour.
Like green mizuna, the red variety is exceptionally rich in nutrients: it contains vitamins A, C and K, folic acid, calcium, iron and antioxidants that protect cells from oxidative stress.

Common problems and solutions
| Problem | Possible cause | Solution |
| Bitter taste | High temperatures, older leaves | Pick younger leaves, grow in cooler conditions |
| Holes in the leaves | Caterpillars or slugs | Protect the plant with netting, use natural repellents |
| Weak growth | Nutrient deficiency | Add organic fertiliser or use smart soil |
| Yellow leaves | Too little light | Provide a sunny spot or LED lighting |
| Premature bolting | Heat stress | Keep the temperature stable and harvest the leaves regularly |
The difference between green and red mizuna
- Green mizuna (Brassica rapa var. nipposinica): light green leaves, milder flavour.
- Red mizuna (Brassica rapa var. nipposinica ‘Red Mizuna’): dark red leaves, visually striking, with a slightly more peppery flavour.
How to store red mizuna
- In the fridge: store in a paper or plastic bag for up to 3 days.
- Freezing: not recommended, as the leaves lose their crispness.
- Best used fresh: straight after harvest for maximum nutritional value and flavour.
