Cranberry (Vaccinium macrocarpon). Ericaceæ.
The cultivated cranberry is propagated entirely by cuttings. These are made from vigorous young runners, from six to ten inches in length, and they are thrust obliquely into the soil until only an inch or two of the tip projects. Some blunt instrument, as a stick, is commonly used to force them into the sand of cranberry bogs. Planting is done in the spring, and the cuttings are taken just previous to the operation. If cranberry seedlings are desired, the seeds should be sown in flats of peaty earth, which are stored until spring in some protected place, in the manner of stratification boxes. The seeds should be covered lightly, preferably with fine moss. The plants are allowed to grow the first year in the box.
Crassula. Crassulaceæ.
Seeds; also by cuttings, which should be taken off and laid for two or three days in the sun to dry before planting.
Cratægus (Haw, Hawthorn). Rosaceæ.
Propagated by stratified seeds. Some growers spread the haws in shallow piles in the fall, and allow them to decay, so that most of the pulp is removed before they are stratified. Haws often come irregularly, even from stratified seeds. The varieties are grafted, rarely budded, on common stocks.
Cress (Lepidium sativum). Cruciferæ.
Seeds, sown at any time of year. See [Water-Cress].
Cress, American. See [Barbarea].
Cress, Rock. See [Arabis].
