Kohlrabi White Vienna Vegetable Seeds

KOHLRABI ‘White Vienna’ Vegetable Seeds

Botanical Name: Brassica oleracea var. gongylodes

‘White Vienna’ is a classic green kohlrabi variety, prized for its mild, sweet flavour and smooth, pale bulbs. The edible stem swells just above the soil and can be enjoyed raw, grated into slaws, or cooked in stir-fries and roasts. When harvested at 7–10 cm diameter, the flesh remains tender and juicy.

This fast-growing variety thrives in cooler temperatures, making it ideal for autumn and spring sowing across New Zealand. Compact plants with minimal space requirements make it a popular choice for raised beds and home gardens.
