Gingko Or Maidenhair Tree (gingko Biloba)







Distinguishing characters: The *peculiar branches* of this tree *emerge

upward* from a straight tapering trunk *at an angle of about 45 deg.*

and give to the whole tree a striking, Oriental appearance, which is

quite different from that of any other tree, Fig. 44.



Leaf: Like that of a leaflet of maidenhair fern, Fig. 45.



Range: A native of northern China and introduced into eastern North

America.



Soil and location: The gingko will grow in poor soils.



Enemies: Practically free from insects and disease.






Value for planting: It makes a valuable tree for the street where heavy

shade is not the object and forms an excellent wide-spreading

specimen tree on the lawn.



Other characters: The _fruit_ consists of a stone covered by sweet,

ill-smelling flesh. The tree is dioecious, there being separate male

and female trees. The male tree is preferable for planting in order

to avoid the disagreeable odor of the fruit which appears on the

female trees when about thirty years old. The male tree has a

narrower crown than the female tree. The buds (Fig. 46) are very odd

and are conspicuous on the tree throughout the winter. The leaves of

the gingko shed in the winter. In this respect the tree is like the

larch and the bald cypress.






The gingko belongs to the yew family, which is akin to the pine

family. It is therefore a very old tree, the remains of the forests

of the ancient world. The gingko in its early life is tall and

slender with its few branches close to the stem. But after a time

the branches loosen up and form a wide-spreading crown. In the

Orient it attains enormous proportions and in this country it also

grows to a fairly large size when planted on the open lawn or in

groups far apart from other trees so that it can have plenty of room

to spread. It then produces a picturesque effect of unusual

interest.
