Ruby Streaks Mustard - Organic


Ruby Streaks Mustard - Organic

Brassica juncea
(40 days) Open-pollinated. As if an artist had carefully brushed deep purple filigree on the delicately serrated leaves of mizuna. Anne Elder of Community Farm in Ann Arbor describes it as “a sweet flash of color for any raw dish.” Clayton Carter calls it “everything that the so-called Purple Mizuna should be.” Bold coloring on deeply toothed leaves. Germinates quickly, grows speedily but, unlike Mizuna, bolts rapidly. Great for multiple spring and fall cuttings, but cannot stand heat. Provides a striking contrast when bunched with Mizuna, Tokyo Bekana or Maruba Santoh. Also unlike Mizuna, has a sweet and spicy flavor, though not excessively hot. Even after it bolts, its flower buds and yellow flowers can add a tang to salads. Carter calls it “the staple of my salad and braising mixes.” “A big hit with my chef clients,” reports Georgie Smith of Coupeville, WA. Color deepens toward darker maroon in the cool of autumn. Tested negative for BR and BL.

Additional Information


About 8,750-22,000 seeds per oz, with wide variability among varieties.

Versatile for tasty microgreens. Mustards are potent soil fumigants. Incorporating the residues of mustard crops into your soil can reduce fungal diseases in your succession crop. See Mustard from Organic Growers Supply for a cover crop, and Yellow (White) Mustard for culinary mustard.

Saving Seed: Saving mustard green seed is easy! Let your spring sowing of mustards bolt. The flowers develop into narrow seed pods. Once pods dry on the stems, they can be easily broken open for seed. To ensure true-to-type seed, grow only one open-pollinated variety per season (or let only one flower!)
