means Tatsoi is an Asian leafy green with small, spoon-shaped dark leaves that grow in a flat rosette, used raw in salads or quickly cooked, and prized for its mild, slightly mustardy flavor.

from The name comes from Japanese, where it's written with characters meaning roughly 'flat (collapsed) vegetable' — a nod to the way the plant hugs the ground in a low, splayed rosette. It's a variety of Brassica rapa, the same generous species that gave us turnips, bok choy, and napa cabbage, so its real family ties run deep through the East Asian garden.
