12 • ORNAMENTAL TREES 
HORSE CHESTNUT The most beautiful tree in May— with tall rounded dome 
(^sculus Hippocastanum) of handsome green leaves and large showy clusters or pyr- 
amids of white flowers mottled wdth red. Its dense growth and heavy tcnt-like 
leaves make it ideal for shady bowers, roads, or parks in towns and cities in the 
North and Eastern United States, where it thrives best and is extensively planted. 
LINDEN, OR BASSWOOD White, fragrant flowers, which attract bees. Large 
(Tilia Americana) heart-shaped leaves. A rapid grower, often reaching 
a height of 90 feet. 
MAPLE, NORWAY A large rounded tree. Dense foliage, smooth, glossy, dark 
(Acer Platanoides) green, turning yellow in the fall. One of the best and long- 
est lived for street, park, or garden. Grows to 100 feet. 
MAPLE, SILVER LEAF The White or Silver Maple is a large, fast-growing tree. 
(Acer Saccharinunx) Very attractive. Should be planted alternately with 
the slower-growmg but more permanent Sugar or Norway Maples, and cut out 
w hen the latter have attained a good size. Grows to 120 feet. 
MAPLE, SUGAR The Hard or Rock Sugar Maple is the best park, shade, and 
(AcerSaccharum) street tree of all. Beautiful dark green foliage, which turns 
red and yellow in the autumn. Moderately fast-growing, but hardy, vigorous, and 
long-lived. Grows to 100 feet. 
POPLAR, CAROLINA Fastest-growing tree; slender, sometimes 100 feet high 
(P. carolinensis) Shiny, bright green leaves. Best for crowded districts ot 
large cities and as a quick shade tree. Sometimes called "the sudden sawlog." 
Grows 75 to 100 feet. Sliould be planted alternately with more permanent trees. 
Does well in arid States. 
POPLAR, LOMBARDY One of the most striking and picturesque trees. A tall, 
(Fopulus Nigra Italica) narrow, columnar tree, growing 60 to 100 feet straight 
up The tall spire-shaped tops are landmarks in almost every populated region 
from the Atlantic to the Pacific, and from the Canadian frontier to the Mexican 
boundary. Longer-lived than the Carolina Poplar. Bright, glossy green leaves. 
Used as a windbreak, as it does not spread out; also extensively planted in the 
Western country to prevent blowing of sand. It is of special value in landscape 
work where it is planted to relieve monotonous sky-lines and to increase the 
apparent height of hills. 
RUSSIAN OLIVE (Oleaster) The Russian Olive is a large shrub or small tree, 
(Elsoagnus Angustifolla) 12 to 20 feet high— sometimes grows 40 feet. It 
is a rapid, spreading grower when young, and will develop an immense head unless 
kept in shape by pruning. The leaves are small, oval, shiny. The glistening silveiy 
foliage is very pleasing in contrast with the green of other trees. In blooining-time 
it is covered with immense masses of little golden, honey-scented flowers; the bees 
fairly swarm over them. The fruit is oval, yellow, covered with scales, ihe Rus- 
sian Olive is the best tree known for semi-arid regions, as it will stand the most 
heat and drouth. It makes an ideal low, dense windbreak or hedge. Sometimes 
called "the candle tree." Very hardy. 
STAGHORN SUMAC This is a typical Sumac, except that it forms a small 
(Rhus Typhina) tree, 20 to 30 feet tall. Its beauty has been overlooked 
by many planters. Fits in wherever a large shrub or small upright tree is desired. 
The rich, green fern-like foliage gives a tropical effect. The foliage turns a briUiant 
flaming red in the fall, very conspicuous and beautiful. After the foliage is gone, 
long clusters of small, round, crimson-red fruit, covered with velvety hairs, re- 
main during the entire winter. Hardy; grows very fast. Prefers sunlight, (bee 
page 33, under "Shrubs," for the low-growing form of Sumac.) 
SYCAMORE, EUROPEAN (Oriental Plane) A large, round-headed, wide-spread- 
(Platanus Orientalis) ing tree, regularly formed, usually 
with a short, heavy trunk. A beautiful and majestic shade tree. Grows 80 feet 
tall A very good street and avenue tree. Good for all soils, even at the sea-side. 
Succeeds where others fail. More shapely and better tree than the American Plane. 
Bright green, five-pointed leaves. Hardy.
