Description

Wasabi Mustard (Brassica juncea) is an exciting heirloom oriental green prized for delivering the fiery, nasal-clearing kick of true Japanese wasabi in a fast-growing, easily cultivated leaf crop. Featuring bright green, deeply serrated, ruffled leaves, it adds sharp, peppery crunch to fresh salad mixes, sushi wraps, stir-fries, and sandwiches. Extremely fast-growing and cold-hardy, it grows rapidly in spring and autumn, providing a continuous harvest of bold, spicy baby greens or mature leaves.
