214 THE NURSERY LIST. 



Cocoanut ( Cocos n ucifera ) . Palmacece. 



The nuts are buried in nursery rows, and the youn^ 

 trees are transplanted. A more common practice is to 

 remove the buried nuts, when they begin to sprout, to the 

 place in which the tree is to stand. A nut is then placed 

 m a hole some two feet deep, which is gradually filled in 

 as the plant grows. In from six to eight years the tree 

 begins to bear. See Palms. 



Cocos. Palmacece. 



Most species by seeds in heat. Some by suckers. See 

 Cocoanut, above. 



Codiaum, Croton. Euphorbiacea. 



New varieties are produced by seed. Increased by tak- 

 ing off the tops of any strong leading shoots, and making 

 them into cuttings. They may be struck by placing singly 

 in small pots and covering with bell-glasses, in strong, 

 moist heat, where they will soon emit roots, without losing 

 any of the leaves attached at the time they were inserted. 

 Or they may be placed in a bed of sand. 



Coffea (Coffee-tree). Rubiacece. 



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). LiliacecE. 



Seeds, sown as soon as ripe in a protected place. Sep- 

 aration. 



Coleus. Labiates. 



Increased by seeds (which grow readily) for new varie- 

 ties. 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. 70.) 



Collinsonia. Labiates. 



Increased readily by dividing roots of the perennials in 

 spring ; also seeds. 



Colocasia. As for Caladium. 



Columbine. See Aquileeria.
