Shows pleasing colors at all seasons; grows best in a fairly rich, moist soil. 5. Copper beech (_Fagus sylvatica_, _alropurpurea_) Exceedingly beautiful in form, bark, and foliage and possesses great longevity and sturdiness. It is difficult to transplant and therefore only small trees from 6 to 10 feet in height should be used. 6. Coffee tree (_Gymnocladus dioicus_) A unique and interesting effect is produced by its coarse branches and leaves. It is free from insects and disease; requires plenty of light; will grow in poor soils. 7. European white birch (_Belula alba_) A graceful tree and very effective as a single specimen on the lawn, or in a group among evergreens; should be planted in early spring, and special care taken to protect its tender rootlets. 8. Gingko or Maiden-hair tree (_Gingko biloba_) Where there is plenty of room for the spread of its odd branches, the gingko makes a picturesque specimen tree. It is hardy and free from insect pests and disease. 9. Horsechestnut (_Aesculus hippocastanum_) Carries beautiful, showy flowers, and has a compact, symmetrical low-branched crown; is frequently subject to insects and disease. The red flowering horsechestnut (_A. rubicunda_) is equally attractive. [Illustration: FIG. 92.--A Lawn Tree. European Weeping Beech.] 10. Sugar maple (_Acer saccharum_) Has a symmetrical crown and colors beautifully in the fall; requires a rich soil and considerable moisture. 11. Soulange's magnolia (_Magnolia soulangeana_) Extremely hard and flowers in early spring before the leaves appear. 12. Flowering dogwood (_Cornus florida_) Popular for its beautiful white flowers in the early spring and the rich coloring of its leaves in the fall; does not grow to large size. The red-flowering variety of this tree, though sometimes not quite as hardy, is extremely beautiful. 13. Japanese maple (_Acer polymorphum_) It has several varieties of different hues and it colors beautifully in the fall; it does not grow to large size. CONIFEROUS 14. Oriental spruce (_Picea orientalis_) Forms a dignified, large tree with a compact crown and low branches; is hardy. 15. Austrian pine (_Pinus austriaca_) Is very hardy; possesses a compact crown; will grow in soils of medium quality. 16. Bhotan pine (_Pinus excelsa_) Grows luxuriantly; is dignified and beautiful; requires a good soil, and in youth needs some protection from extreme cold. 17. White pine (_Pinus strobus_) Branches gracefully and forms a large, dignified tree; will thrive on a variety of soils. 18. European larch (_Larix europaea_) Has a beautiful appearance; thrives best in moist situations. 19. Blue spruce (_Picea pungens_) Extremely hardy; forms a perfect specimen plant for the lawn. 20.
