(37 days) Open-pollinated. Chinese specialty vegetable also known as Purple-flowered Choy Sum, meaning ‘vegetable heart’ or ‘flowering stem’ in Cantonese. The flower stalks, leaf stalks and buds are deep purple, with color intensifying in cold weather. Grows vigorously in fertile soil, producing up to forty pencil-thick flowering shoots, though much skimpier on poor ground. Shoots and leaves have a pleasant mild mustardy flavor good for stir-fries, braising and soups. Also good for microgreens. Grows best in cool weather, ideal when sown in late summer for a fall crop or in fall for an early winter crop in warmer climates. Hardy to 23°. May bolt prematurely in midsummer heat. ~4,500 seeds/oz. ⑤

Additional Information
Mustards
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!)
Asian Greens
- All open-pollinated except where noted.
- Days to maturity are from emergence after sowing; from transplant, subtract 20 days.
