Read about Celeriac in the Standard Cyclopedia of Horticulture 

Celeriac (Apium graveolens, Linn., var. rapaoeum, DC.). Umbelliferae. Fig. 856. An offshoot of the celery species, producing an edible root-part instead of edible leaves. Celeriac is very little grown in this country, and to Americans is almost unknown, but it is much prized in Europe. Here it is cultivated chiefly where there is a foreign population. Fifteen or twenty varieties are mentioned in the seed catalogues, but there is very little difference in the various sorts, some seedsmen even making no distinction between varieties, but cataloguing the plant simply as celeriac.

In general, the culture is the same as for celery, except that no blanching is required, since it is the enlarged root that constitutes the edible part. Sow the seed during the spring in a well-prepared seed-bed, preferably in a more or less shaded location. A coldframe or a spent hotbed is a good place. The seed is slow to germinate, and must be kept well watered. When the plants are 2 or 3 inches tall, they ought to be transplanted ; about 3 inches apart each way is a good distance to place them at this handling. Later, again transplant them to the open ground, in rows about 2 feet apart and 6 or 8 inches distant in the row. The soil should be a rich light loam well supplied with moisture. (The seed may be sown where the plants are to remain, and thinned to the required distance, but stronger, more stocky plants are secured by transplanting as directed.) Plants thus treated will be ready for fall and winter use. If they are desired for earlier use, the seeds may be sown in a mild hotbed and transplanted to the open.

Aside from frequent tillage, celeriac requires but little attention during growth. It is a frequent practice with growers to remove a little of the earth from about the plants after the root has become well enlarged, and to cut off the lateral roots. This tends to make the main root grow larger, smoother and more symmetrical in shape. For winter use, the plants may be protected with earth and straw to keep out frost, or packed in moist sand and placed in a cool cellar.

The principal use of celeriac is for the flavoring of soups and stews, but it is also served in several other ways. It may be boiled and eaten with a white sauce, like cauliflower; as a salad, either first being cooked as beets or turnips, or else cut up into small pieces and used raw; when boiled, sliced and served with oil and vinegar, it forms the dish known as "celery salad." An extract may be obtained from it which is said to have medicinal properties.

Just how long celeriac, or turnip-rooted celery, has been in cultivation is unknown. Its history as a garden vegetable can be traced definitely as far back as the middle of the seventeenth century, although writers for a century or more previous to this time made references which would seem to relate to this vegetable, but the identity is obscure. Its origin was probably the same as that of the common garden celery, of which it is doubtless a state wherein the root has become enlarged and edible. This form is supposed to be the one most remotely removed from the wild state. H. P. Gould.

Cultivar Group
Apium graveolens Rapaceum Group

Celeriac (Apium graveolens Rapaceum Group) (also known as 'celery root,' 'turnip-rooted celery' or 'knob celery') is a specially selected Cultivar Group of celery, grown as a root vegetable for its large and well-developed taproot rather than for its stem and leaves. The root is used when it is about 10-12 cm in diameter, or the size of a large potato. Celeriac may be used raw or cooked. It is best to peel celeriac before use, since the outer skin is tough and stringy. It has the celery flavor, so it is often used as a flavoring in soups and stews; it can also be mashed or used in casseroles and baked dishes. The hollow stalk of the upper plant can be cut into drinking straw lengths, rinsed out, and used for tomato drinks such as the Bloody Mary. The tomato juice moving through the stalk is lightly permeated with the celery flavor. Nutritionally, celeriac is low in carbohydrates.Template:Fact

Celeriac soup.

It is not as popular as other root vegetables, especially in the western hemisphere, very possibly because of its garish appearance before cleaning: it has been described as "a vegetable octopus" in reference to the tangle of rootlets that grow at the base.

There are numerous cultivars available, especially in Europe, where root vegetables are popular. Among the types are 'Prinz', 'Diamant', 'Ibis', and 'Kojak', which all received Royal Horticultural Society Award of Garden Merit designation in the year 2000 trials.

Celeriac has good keeping properties and should last three to four months if stored between 0° and 5° C and not allowed to dry out.
