C. & O. DECIDUOUS SHADE TREES AND HARDY FLOWERING TREES 
GINKGO 
Maidenhair Tree (Ginkgo biloba). 50 ft. A very unique and 
interesting tree. Foliage resembles maidenhair fern, bright green 
color, yellow in autumn. Beautiful lawn or street tree. Ginkgo 
biloba is the most ancient of tree varieties, perpetuated from 
specimens found in old Chinese gardens. Recent discovery of the 
Ginkgo petrified forest near Vantage in Central Washington has 
brought new interest in this fine tree. 
HAWTHORNE 
Paul’s Scarlet Hawthorne (Crataegus oxyacantha Pauli) 25-30 
ft. A very beautiful ornamental tree, small or medium size, suit- 
able for home grounds and parking strips. Large clusters of 
brilliant carmine-scarlet flowers cover the tree in spring. Small 
red fruits fall and winter. 
LINDEN

splendid tree for street, lawn and park planting. Large, deep- 
green foliage, fragrant yellow bloom.

STREET PLANTING OF GLOBE LOCUST 
LOCUST 
Black Locust (Robinia pseudoacacia). 60-80 ft. A very rapid 
growing tree, covered in June with sweet scented, white flowers. 
Valuable as a quick-growing shade tree, and for its hard wood. 
Globe Locust (R. umbraculifera). 15-20 ft. An outstanding 
formal tree for landscape effects. Especially desirable where 
overhead wires make taller trees impractical. Its top forms a 
very dense, almost perfect globe shape without trimming. Beau- 
tiful acacia-like foliage early in spring until late fall. Our Globe 
Locust have symmetrical heads formed on straight stems 6 to 7 
feet high. This tree can be pruned or sheared each season if 
desired. 
Honey Locust (R. gleditsia triacanthos) . 40-50 ft. Vigorous, 
rapid growing tree, feathery, fern-like foliage. Long thorns and 
seed pods. 
Moss or Rose Locust (R. hispida) . 8-10 ft. Flowers dark rosy- 
pink borne in long, wisteria-like racemes. Makes a beautiful 
semi-weeping specimen when top-grafted and grown as a stan- 
dard. Attractive bright green foliage. 
Pink Flowered Locust (R. decaisneana). 40 ft. A fine new 
tree similar in foliage and habit of growth to Black Locust, bear- 
ing clusters of deep pink flowers. Rapidly grows into a strong 
large tree. Distinctive for its outstanding beauty of flower. 
Blooms intermittently throughout summer. Very few, if any, 
seeds.

symmetrical, rounded top. Attractive, dark-green foliage. Per- 
fectly hardy. One of the best shade trees; also one of the best 
street trees. Fast growing for a hardwood tree. 
Red Maple (A. rubrum). A native maple of the eastern for- 
ests. Medium size, symmetrical, rounded top. Valued for its 
brilliant scarlet foliage in autumn. Hardy.

beautiful; in early spring its leaves are bright red, later changing 
to dark green; in autumn golden yellow. A distinctive and hand- 
some tree. 
Silver or Soft Maple (A. dasycarpum). A rapid growing tree; 
large and spreading; excellent for quick shade. Leaves green 
above and silvery beneath. Hardy and easily transplanted. 
26 
Sugar Maple (A. saccharum). A well known native of the 
eastern woods. Stately growth, beautiful form and foliage; foli- 
age assumes highly colored autumn tints. Slow grower. Very 
hardy. 
Sycamore Maple (A. pseudoplatanus). A handsome tree of 
rapid, upright growth. Smooth, ash-gray bark. Large, deep- 
areen leaves, glaucous beneath. Desirable shade tree. 
Japanese Red-leaved Maple. (See Shrubs.)

park planting. 
MULBERRY 
Russian Mulberry (Morus alba tatarica). Very hardy, rapid 
growing small tree; rather bushy top. Fruit in abundance, varies 
in color from white to violet color; fruit greatly relished by birds. 
lf planted near cherry trees will attract birds away from cherry 
crop. 
American Mulberry. A hardy, ornamental tree with leaves 
larger than other varieties, and especially valuable for its large, 
sweet, glossy black berries, which are edible and ripen from June 
to September. Ranks among the best for fruit. Should not be 
planted where ripening fruit will fall on walks or grass. 
OAK 
Scarlet Oak (Quercus coccinea). Tall grower; leaves deeply 
cut. The autumn color is particularly striking in deep scarlet. 
POPLARS 
Bolleana Poplar (Populus Bollena). 50-60 ft. Tall, narrow- 
topped tree; grayish-green bark, foliage dull green above, sil- 
very beneath. Similar habit of growth to Lombardy, but longer 
lived, more durable. Fast grower; will thrive anywhere. 
Carolina Poplar (P. monilifera). 75-90 ft. Particularly suit- 
able for planting where quick results are of first importance. 
Thrives under almost any condition, but responds readily to 
plenty of water. Recommended for planting with other trees of a 
permanent nature so that poplars may be removed in eight or ten 
years. 


SCHWEDLERI MAPLE 
Lombardy Poplar (P. nigra italica). 60-80 ft. Tall, spire-like 
outline makes it picturesque feature of any landscape. Often 
attains a height of 50 feet with a spread of less than 10 feet.
