PLANE TREE (Platanus orientalis).
For towns the Plane has the best character, but other good trees are Wych Elm and Hornbeam, Sycamore, Maple, Lime, Lombardy Poplar, and Horse Chestnut. The spreading growth of the Horse Chestnut commends it rather for a space like the place of a foreign town. Here is also the place for Limes, for though they are good street trees, yet when in bloom the strong, sweet scent, although a passing whiff is delicious, might be an annoyance if poured continuously into the windows of houses during the blooming time.
The Wild Cherry, with its quantity of early bloom, would be a beautiful street tree, and in places where trees of rather smaller growth are desired there is the Bird Cherry and the Mountain Ash. The large American Mountain Ash is a good street tree, in autumn loaded with its handsome bunches of scarlet fruit.
The larger Willows are also charming trees for streets. Many of the trees named, if their tops spread too near the houses, may, with good effect, be pollarded about 10 feet from the ground.
CHAPTER XXIII
TREES AND SHRUBS IN SCOTLAND
The following list has been kindly sent me by a great lover of trees and shrubs who lives at Forres. My correspondent writes: "I have grown all the plants in my list in my own garden, except Buddleia globosa and Aralia chinensis, but the latter is grown in quantity by several of my neighbours, and there are also several fine plants of the Buddleia in many gardens in sheltered spots. My experience is that many plants are quite frost-proof but cannot stand cold winds. This applies more especially to the shrubby Veronicas. I have seen them in the Edinburgh Botanic Gardens as if scorched with fire on the exposed side, while they were untouched where sheltered from the north and east. My own garden is fairly well sheltered."
