This plant is used to a great extent in beds and borders, especially 

 where a showy plant is needed. This is not the popular fall-flowering 

 type of chrysanthemum. In Figs. 43 and 46 the popular greenhouse, or 

 fall-flowering, types are shown. 



Good varieties are Coronarium — which may be white or yellow, 

 double or single — and Tricolor. 



Cockscomb 



Cockscomb plants may be grown from seeds sown in the hotbed the 

 first of April or in the cold-frame in May, and transplanted to the 

 open ground about the middle or last of May. If rich soil is supplied 

 for the transplanted seedlings, the result will be larger flower masses 

 than would otherwise be obtained. The rows should be 18 inches 

 apart for the low varieties and 24 inches for the tall, and the plants 

 12 and 24 inches, respectively, apart in the row. The average height of 

 the low varieties is 12 to 18 inches, and of the tall varieties 36 inches. 



There are two distinct types of cockscomb, the Cristata and the 

 Plumosa. The latter is by far the more decorative of the two. There 

 are copper-colored, dark crimson, purple, golden-yellow, rose, scarlet, 

 and violet varieties of cockscomb. 



Convolvulus {Morning-glory) 



Convolvulus is an old garden favorite. It is a climbing or running 

 plant, often growing to a height of 10 to 15 feet when trained over a 

 lattice or a trellis or the side of a house. The seed may be planted in 

 the open ground in April, about | to § inch deep, generally in a single 

 row. The plants should be thinned to 6 inches apart. 



The Japanese varieties of morning-glory are desirable, as they 

 have fine, large flowers. Theie is a morning-glory of dwarf habit, called 

 Convolvulus Minor, which has flowers of many colors; the plant grows 

 to the height of but 1 foot. Convolvulus Major, which includes the 

 Japanese and the Double Morning-glory, of mixed colors, is the common 

 climbing or running variety. 



Coreopsis (Calliopsis) 



Coreopsis is a hardy annual or perennial plant that grows to a height 



of 18 to 24 inches. It may be started in the hotbed in March and later 



transplanted to the garden, or the seed may be sown in the open ground 



in April about \ inch deep in rows 18 inches apart; when the seedlings
