ABOUT
Red Mustard (Brassica juncea) is one of the most visually striking microgreens you can grow: deep burgundy-red cotyledons emerge against vivid green, giving your tray the look of a tiny stained-glass garden. Bite into a stem and you get an immediate, clean mustard heat — sharp and aromatic, not harsh — followed by a pleasantly crisp texture that holds up beautifully in dressings and warm dishes alike. Scatter a small handful over an avocado toast, a soft-boiled egg, or a cold soba noodle salad and the colour contrast alone will stop people in their tracks. With seeds that sprout in days, no soaking required, and a harvest window that stretches up to two weeks, this is a variety that rewards impatient beginners and demanding professionals equally.
