Even'Star Chinese Thick-Stem Mustard - Organic


Even'Star Chinese Thick-Stem Mustard - Organic

Brassica juncea
(47 days mesclun, 62 full size) Open-pollinated. When farmer-breeder Brett Grohsgal passed out samples of his winter-hardy greens at two workshops at a PASA conference, this green mustard was the hands-down favorite. Grohsgal believes this mustard has the “best balance between sweet succulence and moderate pungency of any of the five I grow.” He called it Thick-Stem in honor of its enlarged midribs that give a heavier harvest for the farmer and better mass for the restaurant or home chef. Terrific for mesclun and an excellent cut-and-come-again performer with fast regrowth. Grohsgal has bred it for 100% freeze tolerance in Maryland. It survived our overwintering test in Maine. Needs good soil fertility, prefers clay or loam to sand, dislikes drought but can take wet. Breeder Royalties. Cold-hardy.

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!)
