White Kohlrabi Seeds (Brassica oleracea var. gongylodes)

Brassica oleracea var. gongylodes

White kohlrabi, turnip cabbage, stem turnip, kohlrabi: this is the ultimate forgotten vegetable, very popular in Alsace and Central Europe but shunned elsewhere. What we eat is neither a root nor a cabbage head, but a swollen stem that forms at ground level, crisp and slightly nutty.

Characteristics:

• Nutty flavor: subtle and mild, without the bitterness of other cabbages.
• Two possible harvests: in spring, when orange-sized, or in autumn for larger specimens.
• Rapid growth: 4 to 6 weeks between sowing and obtaining the plant.
• Low maintenance: one of the easiest cabbages to grow successfully.

Sowing advice:

• Exposure: sunny.
• Soil: well-drained, moist and rich in nutrients. As with all cabbages, adding well-rotted compost is beneficial. Consistent watering is essential: drought causes the bulb to split.
• Method: sow from March to August, in a nursery bed or directly in place, at a depth of 1 cm. Stagger sowings to spread the harvest from spring to autumn. See how to sow your seeds.

Planting advice:

• Transplant at 4 or 5 leaves, spacing plants 25 cm apart. Do not bury it: unlike other cabbages, the crown must remain at the surface, otherwise the bulb will not form.

Care advice:

• Water regularly and evenly. Mulch around the base.
• An insect-proof mesh placed immediately after planting prevents flea beetles and cabbage whites without any treatment.

Harvest advice:

• Harvest in spring when orange-sized. Autumn sowings produce larger specimens, but remain reasonable: beyond 10 cm in diameter, the flesh becomes fibrous.
• The young leaves can be cooked like kale, so do not throw them away.

Beneficial companions:

• Its rapid growth makes it a good intercrop. It appreciates strongly scented herbs such as hyssop. Also see Delicatess Violet kohlrabi and vegetable garden companion planting.

Benefits for biodiversity:

• Its short cycle allows it to occupy an empty bed between two crops rather than leaving the soil bare.
• If allowed to flower in its second year, it produces clusters of highly nectar-rich yellow flowers, valuable in spring.

Uses:

• Raw, grated into remoulade or cut into sticks for snacking; steamed, baked in a gratin, mashed or stir-fried in a wok. Peel before use.

Saving your own seeds:
As a biennial, it produces seeds in its second year: leave one plant in the ground over winter, then harvest the brown, dry seed pods. Be careful: Brassica oleracea varieties cross very easily with one another, so isolate your seed plant. See saving your seeds.
