Kohlrabi, also referred to as the German turnip, is a biennial vegetable with a low, stout cultivar of wild cabbage. Therefore, a cultivar belongs to the same species as broccoli, cabbage, kale, Savoy cabbage, collard greens, gai lan, Brussels sprouts, and cauliflower. The advantage of kohlrabi is that you can also eat it raw without having to cook. The edible preparations of kohlrabi are made with both the leaves and stem. However, it’s also important to note that it’s the same as turnip, although they have a common name.
The name “kohl” comes from Germany, which means cabbage, and “Rube – Rabi” comes from the Swiss-German variant “turnip,” since the swollen stems resemble the latter. The group name of kohlrabi, Gongylodes, means “roundish” in Greek. In the northern regions of Vietnam, kohlrabi is known as “su hao,” which is also from French “chou-rave.” In eastern India and Bangladesh, kohlrabi is called “ol kopi.” You can also find kohlrabi in the Kashmir Valley in northern India, called “monj-hakh.” The round part is called “monj,” while the leafy part is called “hakh.”
Kohlrabi pronounce in English is “kowl-raa-bee.” In northern India, kohlrabi is called “nol khol,” and in Sri Lanka, it’s called “knoll khol.” Kohlrabi is also native in Cyprus, and it’s called “kouloumpra.” In the Czech Republic, it’s called “kedlubna,” and in Slovakia, it’s called “kalerab.” Therefore, as you can see, kohlrabi has many different names worldwide, which makes it unique. According to European records written by the botanist Mattioli, kohlrabi was discovered in 1554 in Italy. By the late 16th century, the vegetable was grown in Germany, Tripoli, Austria, Spain, England, Italy, and other parts of the eastern Mediterranean.
Kohlrabi was made from artificial selection for lateral meristem growth. As mentioned earlier, the origin of this vegetable is similar to that of cabbage, broccoli, collard greens, kale, cauliflower, and Brussels sprouts. These are the same species as the wild cabbage. Kohlrabi has the same taste and texture as a broccoli stem or cabbage heart, although it’s milder and a bit sweet, with a high ratio of flesh to the skin.
