Ornamental Shrubs, Vines, Etc. 221 



it produces abundantly, and grows well on almost all kinds 

 of soil; not a showy shrub, but desirable for the fragrance 

 of its flowers. 



Sweet Pepper Bush (Clethra alnifolia), Fig. 121. A 

 very hardy native shrub, attaining a height of 3 to 10 feet, 

 producing abundant spikes of beautiful fragrant white 

 flowers in August. It has the habit of spreading by sucker 

 and needs care that too many of these are not allowed to 

 grow; otherwise the flowers will be small and less abundant. 

 It thrives best in a rather moist, sandy or peaty soil. 



Red Dogwood (Cornus sanguined}. A beautiful shrub 

 of large size and especially valuable for winter effect. The 

 branches are bright red, and when planted in contrast with 

 low-trained golden cornel or willow with the snow for a back- 

 ground very beautiful results are often obtained. A group 

 of these shrubs in front of evergreens also gives a good 

 contrast. The fruits are black. 



Variegated-leaved Dogwood (C. alba). The leaves of 

 this shrub are most beautifully variegated with yellow, 

 white, and green, and make pleasing contrasts with dark- 

 green or purple-leaved shrubs. The branches are of the 

 same color as those of the last. There are also variegated 

 forms of other cultivated species. 



Purple-leaved Filbert (Corylus Avellana, var. atropur- 

 purea). This shrub has the darkest foliage of any of its size 

 that I am acquainted with. When it first unfolds it is almost 

 black, but it soon changes to a rich bronze green. It is 

 one of the best for planting in contrast with the golden- 

 leaved elder, golden spiraea, the variegated dog wood, or other 

 shrubs with bright-colored foliage. It should not be forced 

 to grow too rapidly while young, as it is not quite hardy in 

 the extreme Northern States. I know of no specimen 

 of this shrub living that is now more than 10 years old.
