Overview
Mustard Microgreens are tender, 1-2 inch seedlings with cotyledons (seed leaves) ranging from pale to bright green depending on variety, featuring fine, hair-like roots. Ready to harvest in just 6-8 days, they deliver an exceptionally sharp, peppery flavor with intense mustard heat and lingering bitterness. These heirloom microgreens stand out for their concentrated pungency—far bolder than mature mustard greens—making them a potent garnish for salads, sandwiches, Asian dishes, and grain bowls where a small amount adds significant spicy bite. Their quick turnaround and minimal space requirements make them ideal for indoor growing.
