Heirloom. This rapidly growing member of the cabbage family produces a greenish-white enlarged stem with short tops and few leaves. Slow to bolt and early producing, White Vienna is best harvested when the stem reaches 2-3" in diameter. For best growth, irrigation is essential through dry periods. Flesh is white with a nutty flavour when eaten raw and a mild cabbage taste when cooked. Sow seed every two weeks from April through to early August. Like Purple Vienna Kohlrabi, White Vienna is a pre-1860 variety.
