Description

Brown Mustard (Brassica juncea) is a fast-growing, multi-purpose heirloom grown for its sharp, pungent seeds and spicy green foliage. A staple ingredient in artisanal coarse-ground Dijon mustards, pickling blends, and Indian curries, it adds a bold kick to culinary dishes. Highly versatile in the garden, it functions equally well as a fresh salad green, a high-yielding seed crop, or a biofumigant cover crop that improves soil health.
