Komatsuna Japanese Green Boy Seeds

200 Fresh Seeds

Komatsuna ‘Japanese Green Boy’ is a fast-growing, highly productive Asian leaf vegetable, prized for its smooth, tender leaves and mild mustard-spinach flavour. A staple in Japanese cooking, it’s incredibly versatile—perfect for stir-fries, soups, steaming, or even fresh in salads when picked young.

This variety produces upright, glossy green leaves with crisp stems, offering a clean, slightly sweet taste without the bitterness found in some brassicas. It grows quickly and reliably, making it ideal for cut-and-come-again harvesting, so you can enjoy multiple pickings from a single sowing.

Exceptionally easy to grow, Komatsuna thrives in cooler conditions and is well suited to UK gardens. It performs well in beds, containers, or greenhouse growing, and is perfect for succession sowing throughout the season to keep a steady supply of fresh greens.

A fantastic choice if you’re looking for a nutritious, fuss-free crop that delivers both flavour and yield.
