Mustard Greens – Red Giant




Walking through a bed a Red Giant Mustard is like being transported into a Jurassic ecosystem. Its massive, deep burgundy leaves with green midribs seem like they were born in another time and place, when everything was bigger and bolder. Mildly flavored in the baby leaf stage and gaining some spice at maturity, this Japanese mustard is great both raw in salads and cooked into stir-fry or soups.

Days to Maturity: 20 to baby, 45 to full size
Latin name: Brassica juncea
Life cycle: Annual

Planting Instructions:
Direct seed as soon as soil can be worked or start indoors 2 weeks before transplant.
Seeding depth: ¼”. Full-sized plants: transplant 8-12” apart with 12-24” between rows.
Baby leaf: direct seed 4 seeds/inch with 5” between rows.

All of our seed is Non-GMO and Certified Organic by Washington State Department of Agriculture. We grow the majority of our varieties here at Deep Harvest Farm on Whidbey Island while we purchase the rest from other small, organic Northwest seed growers. Finally, all of our offerings are open-pollinated (OP) so that you too can save and share seed from these plants!
