Coffea (Coffee-tree). Rubiaceæ.
Propagated by seeds. Also by ripe cuttings, which strike freely in sand under glass, in moist heat; and the young plants so raised produce flowers and fruit more readily than those grown from seed.
Coffee-tree, Kentucky. See [Gymnocladus].
Colchicum (Autumn Crocus). Liliaceæ.
Seeds, sown as soon as ripe in a protected place. Separation.
Coleus. Labiatæ.
Increased by seeds for new varieties. By cuttings with the greatest freedom at almost any time of the year, and, with a good moist heat, they will quickly form fine specimens. ([Fig. 53].)
Colletia. Rhamneæ.
Increased by cuttings of half-ripened wood, six to eight inches in length, in a cool greenhouse.
Collinsonia. Labiatæ.
