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.

    ZONE 9B in Houston, TX. See photo on left. I harvested thru winter and early spring. I only pulled them b/c needed more space for starting summer garden. Nice flavor between spinach & mustard. Fast growing. cut as needed to drop in Asian noodle soups. they don't look like pic on packaging. I will keep growing these. I recommend.

    I grow in the desert and am not a representative buyer of your products but have been pleased with most varieties tried so far.

    I loved these mustard spinach seeds. I grew a few plants all through fall and winter in Houston. I had a constant supply of leaves for my sandwiches and wraps, and once they started bolting I decided to let them go until spring.

    Not only were the leaves delicious, when the plant flowered it attracted dozens of bees!
