Winner Kohlrabi


Winner Kohlrabi

(45 days) F-1 hybrid. Longtime customer Brian Cramer of Hutchins Farm in Concord, Mass., convinced CR to grow kohlrabi again for the first time in fifteen years. “Winner,” Cramer said, “has been my most successful kohlrabi for many years, always beating out others I have tried in consistency, quality and appearance.” CR grew Winner in 2012 and it proved to be everything Cramer said. Direct-seeded in late June into a severe drought, irrigated sparingly, thinned belatedly, it even survived his two-week midsummer absence and nevertheless produced its lovely green stem bulb three weeks ahead of Early White Vienna. Its tender sweet flavor was a revelation. Perhaps you, too, have overlooked this unusual under-rated vegetable, or maybe you were just waiting for us to offer a real Winner? Tested negative for BR and BL.

Additional Information


Brassica oleracea (gongylodes group)

~6,000 seeds/oz; 210 seeds/g. Don’t like kohlrabi? Try harvesting it young when it tastes like a humble version of the globe artichoke. Its texture turns tough, woody and inedible if you wait too long.


Days to maturity are from direct seeding. Subtract 20 days from date of transplanting.

Note: We cannot ship packets greater than ½ oz. (14 grams) of any Brassica into the Willamette Valley. The State of Oregon prohibits shipping any commercial quantity of untreated Brassica, Raphanus or Sinapis because of a quarantine to control Blackleg.

Culture: Hardy. Require warm temperatures to germinate (68-86° ideal) but need 60s during seedling stage for optimal growth; higher temperatures make seedlings leggy. Heavy feeders; for best growth, need regular moisture and 2–3' spacing. Have done well for us succeeding onions and garlic in beds. Cauliflower and broccoli are damaged by hard frosts, especially in spring.

Young broccoli sproutlings make good microgreens.
