Kohlrabi ‘Kolibri F1’ is suitable for summer and autumn cultivation. A uniform summer variety that thrives in several climate conditions, including cool weather. The bulb has a particularly attractive purple skin, while the flesh is white and nearly fibreless.

Harvest ‘Kolibri F1’ when the bulb is around 8-13 cm in diameter. If harvested later, the bulb can be woody and the structure becomes tough and fibrous. When the leaves are removed, the kohlrabi can be kept in the refrigerator for a couple of weeks.
