Komatsuna Red is a striking variety of Brassica rapa var. perviridis, a Japanese leafy green also known as “spinach mustard.” The “weeping” part refers to its delicate, arching leaves, which boast a rich, deep red-purple hue. It’s as beautiful as it is tasty and nutritious! Komatsuna originates from Japan, where it has been a culinary staple for centuries. This variety, with its vibrant red tones, is a modern twist, bred for both flavour and visual appeal in the garden or on the plate.

Komatsuna Red is wonderfully versatile in the kitchen! Stir-Fried: Lightly sauté with garlic, sesame oil, and soy sauce for a quick side dish. In Soups: Add it to miso soup or broths for a pop of colour and nutrition. Raw: Use the tender young leaves in salads for a peppery, slightly mustardy flavour. Pickled: Try it in traditional Japanese tsukemono (pickles).

How to Grow Weeping Komatsuna Red from Seed:

When to Sow:

Sow seeds in early autumn or spring, depending on your climate. In mild regions, it can grow year-round.

Where to Sow:

Sow directly in the garden or in pots. Komatsuna doesn’t mind being crowded, so it’s also great for small spaces.

How to Sow:

Sow seeds about 1 cm deep, spacing them 10–15 cm apart for baby leaves or 20–30 cm apart for larger plants.
Rows should be spaced 25–30 cm apart.

Watering:

Lightly water after sowing and keep the soil consistently moist during germination, which takes about 5–10 days.

Care Tips:

Thin seedlings if overcrowded to encourage healthy growth.
Mulch around the plants to retain soil moisture and suppress weeds.
Fertilise every few weeks with a nitrogen-rich organic fertiliser to encourage leafy growth.

Harvesting:

Begin harvesting baby leaves in about 25 days or wait 40–50 days for mature leaves.
Regular picking encourages more growth, so don’t be shy about snipping what you need!

Extra Notes:

Komatsuna Red is beautiful in edible landscapes, adding colour to garden beds or pots.
It’s fast-growing and can even regrow after cutting, making it an excellent choice for continuous harvests. Great for beginners—hardy, forgiving, and delicious!

Enjoy growing this vibrant and nutritious Japanese green—it’s as rewarding to cultivate as it is to eat!
