Gigante Kohlrabi

(130 days) Open-pollinated. You might guess that these get enormous. And they do, regularly exceeding 10" in diameter and 10 lb. Unlike other kohlrabi, this Czechoslovakian heirloom doesn’t get woody even at such a large size. A root cellar staple, Gigante’s crisp white mildly tangy flesh will add zest to your meals while you await the first edible greens of spring. Sow in spring for late fall harvest. Leaves sweeten like a tender kale after a few hard frosts in the fall and stems likewise become as delicious as their broccoli counterparts. A favorite of Jason Kafka who plants a 300' bed.

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.
