The Magdeburg chicory is the variety usually spoken of, it being the one most extensively grown. The roots of this, after being ground and roasted, are used either as a substitute or an adulterant for coffee.
The Witloof, a form of chicory, is used as a salad, or boiled and served in the same manner as cauliflower. The plants should be thinned to 6 inches. In the latter part of summer they should be banked up like celery, and the leaves used after becoming white and tender. This and the common wild chicory are often dug in the fall, the leaves cut off, the roots packed in sand in a cellar and watered until a new growth of leaves starts. These leaves grow rapidly and are very tender, making a fine salad vegetable. One packet of seed of the Witloof will furnish plants enough for a large family.
