256 ROCK GARDENS 



C. Cheiri. — The old-fashioned flower, with its shades of yellow, 

 orange, and purplish-red, both double and single. In ordinary 

 garden soil these grow rank and coarse, but on the tops of walls 

 they form stout, dwarf little bushes, covered with flower during the 

 summer. 



C. miitabilis. — Old walls and dry banks. A shrubby plant, grow- 

 ing 2 to 3 feet high. Orange-purple-coloured flowers and buds deep 

 red. Quite hardy, and of easy culture. A pretty and distinct little 

 plant. Increased by division. Other varieties : Allionii^ hybrid 

 growing 1 2 inches high ; flowers deep orange. Marshalii^ another 

 hybrid with orange-coloured flowers. 



Chimaphila (Ericaceae) 



Low-growing evergreen shrubs of the Heath order, from North 

 America. 



C. 7naculata (syn. Pyrola 7naculata). — Sandy, peaty soil in shady, 

 but not wet position. Grows only 3 to 6 inches high. Small, 

 glossy, leathery leaves, upper side variegated with white, under 

 surface red. White pendulous flowers in June. Rather difficult 

 to grow. Increased by division. 



C. U7nbellata (syn. Pyrola timbellata). — Same soil and position. 

 Reddish-coloured flowers, rather larger than the last, and leaves 

 unvariegated. Both increased by careful division. 



Chiogenes hispidula (syn. Gaultheria serpyllifolia), 

 Creeping Snowberry 



Wet, peaty soil in a shady, cool spot. A creeping evergreen 

 plant like a small Cranberry. Small white flowers and round white 

 berries. A plant for the bog garden. 



Chrysanthemum (Compositae) 



The section of this genus, better known as Marguerites, though 

 as a rule more suitable for the herbaceous border, gives a few 

 varieties of dwarfer habit which would look well in the rock 

 garden. 



C. alpinum (syn. C. Leucanthejnum). — Likes poor, gravelly soil. 

 Grows only about 4 to 6 inches high, with small, deeply cut, hoary 

 leaves and pure white flowers, with a golden eye, a miniature of 

 the common one-eyed daisy. Blooms in summer. 



C. arcticum. — Grows about 9 inches high. Rosy- white flowers from 

 May to July. A pretty little plant.
