Though these cannot be grown so generally as the other kinds of fruits, there are some who, having devoted their attention to the subject, have succeeded in forming artificial swamps where cranberries have been cultivated with great success. Wherever there is a command, and a plentiful supply of running water, with abundance of peat soil, no difficulty need be experienced in growing cranberries. The two species most worth cultivating are the English and the American.

English (Oxycoccuspalustris).—This grows abundantly in bogs, or swamps, in many parts of England. The fruit is the size of a pea, and the skin pale red; they have a somewhat acrid flavour and a strong acidity.

American (Oxycoccus macrocarpus).—Of this there are three varieties:—

1.  Cherry Cranberry, is large, round, and of a dark red colour, resembling a small cherry.

2.  Bugle Cranberry, so called from the shape being like a bugle bead, long, and approaching an oval. Skin pale, and not so deep a crimson as the other varieties.

3.  Sell Cranberry, is bell-shaped, or turbinate, and of a dark coral red. This is a very large variety, and is a great favourite with American growers.
