List of Shrubs 



J^:> 



the Mullein or Dragon's Head; or in broad and elongated 

 heads, like the Sunflower and Crimson Clover; or in many- 

 branched "umbel," hke the Carrot; or in loose "cymes," 

 like the Apple. 



Every shade of color that is wanted may be secured, thanks 

 to the many varieties and hybrids produced by the horticultu- 

 rists, who are also responsible for the so-called double flowers. 



In shape of flowers, several forms can be recognized of 

 which the following may serve as types: flat like the Dog- 

 wood; rose-like like the Rose and most of the fruit trees; 

 bell-shape Hke the Huckleberry; tubular like the Honey- 

 suckle; funnel-shape like the Syringa, and butterfly-shape 

 like the Pea. 



In size, we have tiny blossoms which become effective only 

 by being clustered; small, delicate ones, which by their pro- 

 fusion are showy, and large, broad or long, more or less 

 coarse ones, which in their singleness are decorative. 



In these points, as elsewhere, similarity is mostly desirable 

 in selecting for groups, contrasts being difficult to devise so 

 that they do not jar. 



In managing shrubs, not only for their form, but for their 

 blossom, the pruning knife is most important. As we have 

 seen under Tamarisk (p. 316), the annual flowering can be 

 influenced by appropriate pruning practice, based on the 

 recognition of the flowering habit. Yet care is necessary 

 not to overdo the pruning and thereby destroy the character 

 of the shrub; regular annual pruning of moderate extent 

 must be the rule. It should also be understood that sun- 

 light is inducive of flowering, while shade retards. 



It should be kept in mind that many shrubs, like the 

 spiraeas, daphnes, and other beautiful species, after a few 

 years blooming, are more easily and severely killed back in 

 severe winters, notwithstanding their entire hardiness (as
