In small gardens where intricacy and variety are desired, but where the limited space prevents the planting of trees and shrubbery in sufficient quantities to effect this purpose, an expedient may be adopted in the form of a screen of trellis work covered with climbing plants. Rustic work is well adapted to form such erections, but is expensive if properly constructed, and if it is not, will soon decay. Smooth slats are perhaps preferable, and when painted of a brownish green color are not particularly conspicuous.
Screens of this kind should be put up so as to present somewhat of an architectural appearance, divided into panels by projecting piers, and the elevation relieved by mouldings, etc. In certain positions it may assume the appearance of a gate-way or entrance to a part of the grounds. Such screens may often be advantageously employed to form a division between the vegetable garden and flower beds. Much of their efficiency and appropriateness will depend upon the manner in which they are connected with surrounding objects.
For really effective growth the hardy grape vine is the most reliable; the Virginia creeper is next in order. Aristolochia sipho, Bignonia radicans, the various hardy clematis, Wistarias, etc.. may be also introduced. In summer any of the free growing annual climbers may also be planted.
