Komatsuna — Japanese mustard spinach — is a certified organic live 2-inch starter plant with broad, glossy, spoon-shaped leaves on slim pale stems. Despite the name it is neither hot like mustard nor oxalic like spinach: the flavor is mild, clean and faintly sweet.

It may be the most forgiving green in the garden. It germinates fast, grows faster, tolerates heat that makes spinach bolt, and shrugs off cold that flattens lettuce, which gives it an unusually long season at both ends of the year. Cut young leaves for salad or let it size up for stir-fries, soups and quick sautés.

Fun fact: the name comes from the Komatsugawa district of Edo-era Tokyo, where it was grown for the shogun's table — reportedly named by Tokugawa Yoshimune himself.
