Komatsuna seeds grow into delicious mustard spinach. Sometimes referred to as Japanese mustard spinach, it is milder than the average mustard leaf, yet this variety with its white stems and thick leaves is filled with goodness and the delicious mustard taste without the spicy reputation.
 
Komatsuna seeds produce tender, mild mustard greens ideal for salads and stir-fries. Sow from March to September, either directly outdoors or in pots. These Japanese mustard spinach seeds thrive in cool weather and mature quickly, making them a rewarding choice for gardeners seeking unusual vegetable seeds.
