Komatsuna mustard spinach is a Japanese green that’s a delicious, leafy green. It’s very easy to grow and quickly produces flat and glossy green leaves that can be picked early as baby greens or grown to full size. These plants are hardy and will tolerate heat, cold and dry conditions. These seeds are organic, non-GMO seeds that are locally sourced. Each pack comes with 20 seeds and basic instructions for germination. I’m a USA seller which means faster shipping times as well as higher quality seeds. A vast majority of my seeds either come from my garden, from my neighborhood or in the local area. If not, I’ve acquired them on trips around the country. I’ve tested and grown many of these myself. I’m always here for assistance with germination and growing. Your success is my success!
