Black mustard is an erect plant that grows up to 6 feet tall, producing edible flower heads and leaves. Vibrant yellow flowers grow in clusters and seed pods are closely pressed against its stem.

The black mustard plant produces seeds that are dark brown, gray, or black in color and more pungent and spicy than the seeds of a white mustard plant.

Brown Mustard (Brassica juncea)

Also referred to as vegetable mustard, Indian mustard, and Chinese mustard, brown mustard grows best in partial shade to full sunlight. Leaves can be harvested in as little as 40 days and contain a peppery flavor that ranges from hot to mild.
