Brussels Sprouts, Darkmar 21 (Organic)
Brassica oleracea. Green. 180-260 days.
One of the most reliable, easy-to-grow open pollinated Brussels sprout varieties out there. Firm, sweet, dark green sprouts form on plants that grow to 3½’. We trialed every open pollinated Brussels sprout we could find; Darkmar 21 was the obvious mid-season choice because of its consistent large sprout production and vigor in the field. A classic Brussels sprout variety that is popular in the UK but not widely available in the US. Originally selected in Bedfordshire, England. Aka, Bedford Darkmar 21.
Seed produced by Ferry Boat Seeds on San Juan Island, Washington.
As required by the Oregon Department of Agriculture and the Washington Crucifer Quarantine, all Brassica family seed lots have been tested and found negative for blackleg (Phoma lingam) by an approved, certified lab.

Sow indoors in flats with good potting soil April through early June, for sprouts in November through February. Transplant into the garden about 3-4 weeks after emergence. For optimal sprout production, pinch growth tip off in late August. Harvest sprouts after autumn frost and as needed throughout the winter.
Collect seeds from 50 or more plants (to avoid inbreeding) in the second year when pods are dry. Dance on seed stalks on a tarp to thresh. Collect seeds and winnow to clean. Isolate from other B. oleracea by ½ mile.
