50 Seeds Black Mustard Brassica nigra Edible Herb and Leafy Green Culinary Microgreens

Black mustard is an annual leafy green and spice crop grown for its peppery leaves and pungent seeds. It is a fast-growing cool-season plant that performs well in garden beds, containers, and as a cut-and-come-again green. Its quick maturity makes it a reliable choice for succession sowing and for adding bold flavor to the kitchen.

The young leaves bring a sharp, mustardy kick to salads, sandwiches, and stir-fries, while the mature leaves work well cooked as a pungent green. The seeds are used whole or ground as a spice in pickling, curry blends, and sauces. Plants grow in a compact upright habit, produce yellow flowers that attract pollinators, and can be harvested at multiple stages for both leaf and seed use.
