Green Foliage. Some trees and shrubs are exceedingly interesting in the landscape composition because of the varying and vivid colours of their autumn foliage, ranging from brown or brownish yellow, through to vivid scarlet and bright red. There is another group of shrubs which are not so valuable because of the autumn colour of their foliage, but because of the fact that their foliage is retained until extremely late in the fall, or possibly into the early winter. Such shrubs as the privets, and many others shown in this list, are very valuable in landscape plantations where the owner cannot, because of climatic or soil conditions, resort to the use of evergreens, and is still desirous of producing a foliage effect that will serve as a background or a screen until late into October or early November. Many of these shrubs are somewhat tender and the fact that they do carry their leaves unchanged until late in the autumn often shows that they are not able to mature their wood during a normal growing season. Since they often do not mature their leaves they are also liable to go into the winter with tender wood. Many of the shrubs given in this list should therefore not be planted in exposed places.

I. Shrubs:

Abelia grandiflora Hybrid Abelia Aralia pentaphyla Five-leaved Angelica Berberis wilsonae Wilson's Barberry Chaenomeles japonica Japanese Quince Cotoneaster adpressa Creeping Cotoneaster Cotoneaster horizontalis Prostrate Cotoneaster Eleagnus multiflora rotundifolia Round-leaved Gumi Evonymus bungeanus semipersistens Half-evergreen Spindle Tree Fontanesia fortunei Fortune's Fontanesia Forsythia viridissima Dark green Golden Bell PLATE XXVI. The use of Bay-trees in tubs is required in many of the northern gardens to produce accent points often at spots where no permanent plant can be planted in the ground. These trees are stored in cool greenhouses during the winter months. (See page 146, group XVI-C) at spots where no permanent plant can be planted in the ground. These trees are stored in cool greenhouses during the winter months. (See page 146, group XVI-C) PLATE XXVII. A pleached allee may form not only a most interesting feature as shown on Plate No. XXIV, page 158, but this one serves as a solid screen between the lawn area and the service buildings.
