BoccoNiA CORD AT A {B. Japonico), — A large, strong- 

 growing plant, with large leaves. Fine for emphasis at 

 medium distances. Five to eight feet. 



Callirhoe involucrata. — A good, small, trailing 

 plant with an abundance of purplish flowers. 



Campanula, Bluebell, Harebell. — Easy to grow and 

 always attractive. The genus numbers several fine spe- 

 cies, such as C. Carpathica, C. medium^ C. noUlis, C, 

 punctata, C. rotundifolia, C. grandis, etc. 



Chrysanthemum. — This genus contains several hardy 

 species, some of them known as daisies or marguerites. 

 Probably C. maximum is the best, though others are 

 very good. 



Coreopsis. — Fine, free-flowering plants with large, 

 golden blossoms. C. grandiflora and C. lanceolata are 

 the best of the perennial species. Fine for cut flowers. 



Delphinium, Larkspur. — The perennial larkspurs 

 are very showy and valuable plants. They may be had 

 in numerous species and varieties. Those commonly 

 grown are hybrids. 



Digitalis, Foxglove. — Well known plants of easiest 

 culture, free flowering and always desirable. The com- 

 monest species, with very large flowers in a variety of 

 colors, goes unrler tlie doubtful name of D. gloxinimflora; 

 but B. lanata, D. Siberica and D. grandiflora are 

 equally fine. 



Helenium. — A very fine and striking plant, partic- 

 ularly the vai-iety, H, autumnale superbum. Furnishes 

 a dazzling glow of yellow late in summer when flowers 

 are scarce. Six to eight feet. 



Helianthus, Sunflower. — Some of the perennial 

 species are very useful in border composition. The best 

 are H. Maximillani and H. orgyalis. These give very 

 striking, though easy and natural, effects. 



Hollyhock. — The old favorite, and one of the most 

 artistically effective plants known. In many colors.
