POTENTILLA fruticosa. Shrubby Cinquefoil. 3 to 4 ft. 
Plant this for clear yellow flowers throughout the sum¬ 
mer. Its peculiar bark and silky leaves make it an at¬ 
tractive shrub, and its ability to grow in any situation 
makes it a very useful one. 
PRIVET. See Ligustrum. 
PRUNUS cerasifera Pissardi. Purple-leaf Plum. 12 to 
15 ft. Although this little tree is valued chiefly because 
of its purple foliage, it is a beautiful bloomer as well. 
The flowers open early in the spring and are pink and 
dainty. It should be pruned each year to get the best 
color effects. 
P. cerasifera, Newport. 12 to 15 ft. The leaves are a 
deeper shade of purple than are those of the Purpleleaf 
Plum. 
P. glandulosa. Double-flowering Almond. 3 to 4 ft. This 
dwarf shrub is almost indispensable because of the show 
produced by the double pink flowers which are crowded 
along the branches in early spring. 
P. Persica (Amygdalus Persica). Flowering Peach. 8 to 
10 ft. A miniature tree whose blooms—pink, red, or 
white—appear before the leaves. The flowers are double 
and are exceedingly decorative.

Cherry. 25 to 30 ft. This late-blooming Japanese 
Flowering Cherry has unusually large, double, pink 
flowers. The foliage is bronze-tinged when young. 
P. serrulata, Kofugen. Red Japanese Flowering Cherry. 
25 to 30 ft. Plant this vigorously upright and sym¬ 
metrical little tree for complete satisfaction. The crimson 
flower-buds expand into double red blooms that fade 
to old-rose. 
P. serrulata, Naden. 25 to 30 ft. Pale pink, semi-double 
blooms are arranged in short-stemmed clusters that 
literally cover the tree and thus make it very showy. 
P. Sieboldi. 25 to 30 ft. A striking little tree with its 
semi-double, white flowers tinged with red. 
P. subhirtella. Japanese Weeping Flowering Cherry. 15 
to 18 ft. No more beautiful sight can be imagined than 
one of these trees, with gracefully drooping branches 
covered with pale pink, single flowers. It is truly the 
essence of spring! 
Douglas-Fir (Pseudotsuga taxifolia) 
Pin Oak (Quercus palustris) 
PRUNUS, continued 
Prunus tomentosa. Nanking Cherry. 6 to 8 ft. This is 
another tree which the bird-lover should cherish, for the 
birds relish the small scarlet fruits. The flowers are showy 
and enclose the tree in a pure white mantle. 
P. triloba. Double-flowering Plum. 8 to 10 ft. This small 
tree is simply a larger edition of the Double-flowering 
Almond. Its increased size makes it even more striking.

Red-Fir. 70 to 80 ft. A pyramidal tree with dark red- 
brown bark, horizontal branches, and dark or blue-

today. The large flowers are sweet scented and purple 
in color.

tractive and interesting plant with its double red flowers 
and unusual fruits. It was written about in sacred 
history and by historians over 300 years before the 
Christian era. 
PYRACANTHA coccinea Lalandi. Laland’s Firethorn. 15 
to 18 ft. A tall-growing evergreen shrub which is gaining 
fast in popularity on account of its beautiful dark green 
leaves, its white flowers in spring, and its wealth of 
orange-scarlet berries coloring in the early fall. The 
berries remain on the plant all winter if they escape the 
birds. The Firethorn may be used in numerous ways, 
one of the least known of which is for covering a wall. 
QUERCUS Darlingtonia. Darlington’s Oak. 50 to 60 ft. 
We consider this to be the best one of the southern Live 
Oaks.

rapid, symmetrical, and stately. Its dense foliage is 
brilliantly colored in autumn.
