34.4 List of Shrubs 
Shepherdia. S. argentea, Buffalo Berry. A hardy native, a slender, 
upright shrub of five to fifteen feet, sometimes in tree form; its silvery- 
white, delicate foliage and light-colored bark is useful for contrast 
effects with darker shades. It is rendered still more attractive by its 
profuse compact clusters of small, yellow flowers (April, May), and its 
bunches of edible crimson fruit (acid), borne only on female shrubs. 
The female can be told from the buds, which are longer and more 
slender, the males being short and blunt. It is a good hedge plant. 
This, and still more its hardier, rusty-colored congener, S. Cana- 
densis Nutt. (82), which is, however, less showy, with red and yellow 
berries, are adapted to cover sterile soils, gravelly banks, etc., but they 
are not quite easily handled. 
Syringa. Lilac. A well-known genus, with some fifteen species and 
very many varieties, from Asia Minor, Persia, Japan, and China, 
familiar in all gardens. The genus name in this country is unfortunately 
used as a common name for Philadelphus, the mock orange, thus occa- 
sioning confusion. They are vigorous growers, sometimes assuming 
tree form, hardy (a number of them to the Canadian Northwest), and 
frugal, adapting themselves anywhere. They are most ready, early 
bloomers (April, May), with large clusters of variously colored, fra- 
grant flowers, which are their chief attraction. They are planted in 
groups, hedges, borders, and as single specimens. With proper selec- 
tion, they may afford a continuous flower show from April to June and 
even July. The foliage of some species is liable to mildew in late sum- 
mer. Pruning in winter and spring would destroy the summer’s bloom- 
ing, as the flowers are borne in terminal buds, but when bloomed off 
the inflorescence should be removed, because they suffer much from 
seed-bearing, which exhausts the reserve materials. 
Six species have served as the basis for the many varieties and hybrids 
of the horticulturists. 
S. vulgaris Linn. (83), the common Lilac, a small, rather bushy tree 
(ten to twelve feet), is familiar to everybody, having been in cultivation 
for three hundred years. The foliage comes early, and remains green 
long into the fall, and the fragrant lilac flowers, which are mostly 
terminal, appear in May. 
Among the more than one hundred very ornamental varieties are 
— alba (83a), with white flowers; alba grandiflora (836), a smaller bush, 
with large, white flower Clusters; Marie Legraye (83c), a dwarf, with an 
abundance of pearl-white blossoms; Charles X (83d), a remarkably
