Kohlrabi Seeds – Non-GMO Heirloom

The crunchy above-ground bulb worth a spot in your garden

Kohlrabi (Brassica oleracea, Gongylodes group) is a fast-growing cool-season member of the cabbage family grown for its swollen, apple-shaped stem that forms just above the soil. The flavor is sweet, fresh, and mildly cabbage-like, closer to a broccoli stem or a crisp radish than to a turnip. Pale green and purple varieties both peel back to crisp white flesh, and the young leaves are edible too. Compact and quick, kohlrabi slots easily into small gardens, raised beds, and containers.

How to grow kohlrabi from seed

Kohlrabi is one of the easier brassicas to start from seed. Sow kohlrabi seeds about a quarter to half an inch deep in full sun and fertile, moisture-retentive soil, then thin seedlings to stand four to six inches apart. Plants size up their bulbs in roughly 45 to 60 days and grow best in the cool weather of spring and fall, when steady moisture keeps them tender rather than woody. Harvest the bulbs young, at about two to three inches across, for the sweetest, crispest eating. For the full step-by-step, see our complete guide to growing kohlrabi from seed.

How to use kohlrabi

The bulb is the prize. Peel it and slice it raw into slaws, salads, and crudite platters, or grate it into fresh kohlrabi remoulade. It roasts, sautes, and steams well, holding a satisfying crunch, and stars in soups and stir-fries. Do not toss the greens: the young leaves cook up much like kale or collards. Its mild, sweet flavor makes kohlrabi a friendly gateway vegetable for kids and picky eaters.

Kohlrabi and its brassica cousins

If you love kohlrabi, you will likely enjoy its cabbage-family relatives. Try broccoli for tender flowering heads, cabbage for dense storage heads, or kale for hardy leafy greens. You can explore the full range in our vegetable seeds collection.
