Beautiful. Fiery. Absolutely not for the timid.

Red mustard microgreens are not here to blend in. Deep burgundy leaves, a slow-building heat that sits somewhere between horseradish and wasabi, and a flavour that makes every dish it touches more interesting. If you enjoy spice - really enjoy it - these are your microgreens.

(Note: Grow trays and medium are not included. This is a seed refill for your Microgreens Pro Kit.)

Why You'll Love Them

  • Bold mustard spice, deep burgundy tones

    With its burgundy-frilled leaves and intense aromatic heat, it’s less of a garnish and more of a spice. It’s perfect for those who find standard salads a bit too quiet.

  • The chef's secret weapon

    Exceptional on grilled meats, smoked fish, ramen, burgers, and bold grain bowls. A small amount goes a long way - the heat is real. Also brilliant paired with something creamy (avocado, burrata, crème fraîche) to temper the burn. Use sparingly until you've calibrated their heat; then use freely.

  • Naturally nutrient dense

    Exceptionally rich in Glucosinolates & isothiocyanates, Vitamins A, C & K, Anthocyanins, Selenium, Omega-3 fatty acids and Calcium.
