Grand Duke Kohlrabi (F1 Hybrid 50 Days)

$ 1.95 Sold Out

The Grand Duke Kohlrabi is the 1979 All America selection winner and still a favorite for both earliness and flavor. Kohlrabi is also called cabbage-turnip and appropriately so, the turnip-like balls are held cleanly above the ground with a cruciferous, “cabbagey” flavor. 4” globes are crisp and tender and Grand Duke holds well, meaning that you can leave it in the garden for a while without it becoming woody.

Seed Sowing Depth: 1/4" deep

Sowing Outdoors: Starting in spring when the soil temperature reaches 60 ºF. Sow seeds 1-2" apart, thin 3-8” apart. The larger the bulb size the more space. Sow in mid to late summer for fall harvest.
