Konan Kohlrabi


Konan Kohlrabi

(38 days) F-1 hybrid. 2016 AAS Winner. Author Robert E. Howard’s sword-and-sorcery hero emerges once again…as a Kohlrabi? Indeed, the legend continues! A nicely rounded 3½" diameter head weighing ⅔ lb, Konan the Kohlrabi’s rampant health and vigor aided its conquest of our 2018 kolhrabi trial, where one Fedco staffer deemed its crunchy crisp texture and mild nutty sweetness “barbarically good.” This bold brassica matured a week earlier than our long-held Winner and showed equally high quality. High resistance to FY. 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.
