Mizuna is a Japanese salad green from the Bassica rapa family that is often found in mesclun.

Dark green and feathery in appearance, with jagged edges similar to arugula, it has a delicate mustardy flavor.

Mizuna has been cultivated in Japan since ancient times and is thought to have originated in China. It can also be cut into a chiffonade and added to soups at the last minute, as it will wilt from the heat of the liquid.
