The bright-green leaves of this heirloom Japanese mustard add peppery zing to mixed-green salads and are delicious simply saut¨¦ed or stir-fried. Plants produce a flurry of thin stalks with bright-green and heavily serrated leaves with a picturesque feathery look that adds interest to the garden bed. A cut-and-come-again plant that keeps producing. Heat-tolerant.
