340 List of Shrubs 



small trees or medium-sized shrubs, twenty North American, of which 

 several are very satisfactory and widely planted ornamentals, being 

 hardy to the Canadian Northwest. They are vigorous growers and 

 attractive in foliage (lobed or otherwise interesting), flower (white 

 heads), and fruit (colored berries), although some species are somewhat 

 straggling in habit. They thrive in partial shade, and heavy, especially 

 peaty soil and swampy ground, but can adapt themselves to other situ- 

 ations. They are best adapted for rough border work in masses to 

 bring out the foliage effect. 



* V. lantanoides Michx. (57) {alnifolium) , Hobble Bush, a low to 

 medium-sized bush from the northeastern United States (five to ten 

 feet), with very large, crinkled, broad (three to eight inches) leaves, and 

 crimson fruit turning black or purple; is one of the most ornamental of 

 the native Viburnums. 



V. Lentago Linn. (58), Sheepherry or Nannyberry, a larger shrub 

 (ten to thirty feet), sometimes tree-like, of similar range, with large, 

 ovate, pointed leaves, and large, showy, white, terminal, flat, flower 

 heads (May, June), followed by red-stemmed clusters of dark blue 

 berries, persisting, in striking contrast with the yellowish autumn foli- 

 age. A variety with variegated, white and yellow, leaves is one of the 

 better class of curios. 



* V. Opiiliis Linn. (59), Cranberry Bush, is one of the best, a medium- 

 sized, vigorous shrub (five to ten feet), and a variety, V. sterile (59a), 

 the old-fashioned Snowball, which has its ball-like flower heads all 

 composed of sterile flowers, while the species ha'^ the sterile, star-shaped 

 flowers only on the outer rim of the flat cyme. The greatest ornament 

 of the species lies in the bright scarlet-red berries, which persist into 

 winter; but the variety is, of course, without this ornament. 



V. dentatum Linn. (60), Arrow-wood, of the same size as the former, 

 sometimes higher, with sharply dentate leaves, is another native swamp 

 shrub, from New Brunswick south; of upright, compact growth, most 

 adaptable and vigorous, with large, showy flower clusters (May, June), 

 and dark blue to purple berries, hanging long into winter. 



V. acerifolium Linn. (61), Dockmackie, a low (five feet), slender 

 shrub from the Northern States, with handsome purple fall color, is 

 well adapted for ground cover, and under trees. 



Of exotics there are at least five worthy of attention. 



* V. macrocephalmn. Hort. (62), the half-hardy, Chinese Snowball, 

 its tree form growing to a height of twenty feet, the sterile variety excel-
