This versatile Japanese green is called mustard spinach, spinach mustard, or komatsuna, but it's neither mustard nor spinach! Whatever its name, this delicious, leafy green is milder than other mustards, very easy to grow, and quickly produces flat, smooth, dark, glossy green leaves that can be picked as baby greens or grown to full size. Hardy and productive plants are slow to bolt and tolerate cold, heat, and dry conditions; although best results in cool weather.

Mustard Spinach

5 out of 5 stars Oct 14, 2019
If Mustard is too tart and Spinach is too mushy then this is for you. It takes the best of both. Mild flavor like spinach, doesn't get mushy when cooked. Great in salad or soup. Here in Georgia we can grow it almost all year, it's coming up now in October and we will have it for Thanksgiving. I give your seeds as gifts and love explaining the packaging to people. Very dependable seed, never had a complaint.

My favorite green. When I'm out picking in the garden, it's impossible to resist snacking on this.
