It can well be called a distinctive summer structure, for with the sun streaming through its mass of vines, it shadows the walks from May until late October. In the long winter months boxed in it stands like a sentinel guarding the long, bare paths, and showing a leafless network of interlacing vines.
The pergola of to-day is not like that of yesterday. When first introduced into our gardens it was taken up on many small estates, and so badly designed that it combined badly with the garden. It was then it fell into disfavor and was pronounced a failure for use in our garden plan.
But landscape gardeners, with an eye to the unique, felt that it was a necessary rounding-out of the garden design, and rescued from ignominy, it took its place in right surroundings, in the heart of the garden with a border of elaborate flower designs. Garden seats were placed inside and when it fronted on an Italian garden, a fountain was often introduced, the musical tinkle of the spouting water giving a special charm.
Among the many designs the simplest is a simple rustic frame structure, appropriate for small or wild gardens. It is formed of cedar posts driven four feet into the ground, and reaching to the height of eight feet. This is covered with a beam or a slab roof structure over which is trained the morning glory, the California creeper, or the grape. This latter is much used, the picturesqueness of the ripening fruit adding to its attractiveness. These pergolas are generally eight feet wide and have for a flooring irregular flags through which peer grass or moss.
This type of garden furniture is perfectly well adapted to Italian, English, or Colonial types of architecture, and is constructed often of marble. It is not merely an ornament but a useful adjunct to a garden, and can be made of concrete, or cobblestone, if one does not wish to go to the expense of using marble.
There is a modern form of this feature that is a development from century-old customs, the porch-pergola which is fast supplanting the old covered porches of yesterday. This is designed with an open, vine-covered roof. It gives an added charm to the exterior of the house and furnishes a shady nook for sunny days, without the drawback of the old porch whose roof darkened the house in winter by withholding the sun.
No one, no matter how small their grounds, need deny themselves a pergola. It is such an important feature and so decorative that it is almost a necessity. For the little backyard it may be simply a rustic porch planted in the middle of the garden. Properly laid out, it can be used as an out-of-doors living room. Across the end a hammock can be swung, while table and chairs can be fitted in at one side.
