Under this name, a great variety of cabbage-tribe plants is grown, some of them reaching a height of several feet. Usually, however, the name is applied to a low-growing, spreading plant, extensively used for winter and spring greens.

The culture given to late cabbage is suitable. At the approach of severe freezing weather a slight protection is given in the North. The leaves remain green through the winter and may be gathered from under the snow at a time when material for greens is scarce. Some of the kales are very ornamental because of their blue and purple curled foliage. The Scotch Curled is the most popular variety. Let the plants stand 18 to 30 inches apart. Young cabbage plants are sometimes used as kale. Collards and borecole are kinds of kale. Sea-kale is a wholly different vegetable (which see).

Kales are extensively grown at Norfolk, Va., and southward, and shipped North in winter, the plants being started in late summer or in fall.

Kohlrabi is little known in the United States. It looks like a leafy turnip growing above ground.

If used when small (2 to 3 inches in diameter), and not allowed to become hard and tough, it is of superior quality. It should be more generally grown. The cuiture is very simple. A succession of sowings should be made from early spring until the middle of summer, in drills 18 inches to 2 feet apart, thinning the young plants to 6 or 8 inches in the rows. It matures as quickly as turnips. One ounce of seed to 100 feet of drill.
