Kohlrabi is a cool season crop in the same family as Brussels sprouts and broccoli. It produces a strongly flavored swollen stem, which is the primary part eaten, although the leaves are also delicious. There are many varieties from which to choose. Each has a different size, color, pungency, growth rate, and pest or disease resistance. Since each of the different types of kohlrabi is so individual, there is a perfect variety for every gardener.

Different Types of Kohlrabi

Kohlrabi varieties are divided into different days to maturity and color. Most develop a round swollen stem, but some varieties of kohlrabi have a more flattened stem. You can find green, purple, white and even blue fleshed kohlrabi. There are also kohlrabi plant varieties that are slow to bolt. There are types that are resistant to certain insects, such as cabbage worms. Whatever special requirements you need from your kohlrabi crop, there is probably a variety to suit your preferences.

There are more than 22 kohlrabi plant varieties from which to choose. In addition to size, color, growth rate, resistance, flavor and shape, you may also opt for varieties with longer storage characteristics. There are also hybrids, heirlooms and open pollinated varieties, as well as types that are slow to bolt. With so many choices, it may be hard to boil it down to just one or two.

Disease resistance may be one place to start. It isn’t worth growing the bulbs if they are going to get chewed on by larvae or succumb to root maggots. Some of the heirloom varieties are the most resistant to pests and disease but may lack the size of some of the newer cultivars.

Gigante is resistant, an heirloom and stores well. Additionally, the bulb is huge but not woody. Another heirloom, Early White Vienna, is a dwarf with a flattened stem and is slow to bolt. There are many other heirloom varieties that offer unique characteristics.
