Early Purple Vienna Kohlrabi:
Delicious cabbage-flavored bulbs that grow above ground. Purple skin and sweet, white flesh; good cooked or raw. Kohlrabi makes a real staple crop, with high yields; cold hardy. A pre-1860 heirloom.
Early White Vienna Kohlrabi:
This old variety is about the same as the purple, except these have pale green skin; mild and tasty.
