Mike Green Giant Mustard Seeds – Heirloom Broad-Leaf Cabbage Mustard (Brassica juncea)

A Versatile Heirloom Mustard for Kitchen & Garden

Mike Green Giant is a standout heirloom broad-leaved mustard — known by growers as Cabbage Leaf Mustard, Heading Leaf Mustard, and Swatow Mustard. Its large, aromatic light-green leaves with striking red veins are mildly pungent and endlessly useful: harvest at any stage from microgreens and tender baby leaves to mature heads for pickling, juicing, stir-frying, and soups. Every part of the plant is edible — roots, shoots, stems, leaves, flowers, and seed pods.
