For covering walls of houses, boulders, stone walls, etc., the ivies are, of course, used more than other vines. Boston ivy is the quickest growing. Japanese bittersweet [Euonymus radicans) is a good vine for walls, too; evergreen, it grows well on the north sides of buildings as well as on exposed locations. Winter-creeper, in both large and small-leaved varieties, is a hardy vine for wall planting.
Other vines that can cling without aid to concrete, brick and stone include Chinese trumpetcreeper, English ivy, Lowe ivy and Virginia creeper, sometimes called woodbine or American ivy. Virginia creeper is the ivy that twines around trees and covers the ground in woodlands, and while it makes a good building cover, it does become heavy and require thinning out as it grows older. Virginia creeper is also effective for providing shade. (Other shade-producing vines are grape, Dutchman's pipe and silver vine.)
Many vines which are not self-supporting can be trellis-trained, and can add color and beauty to a house. Among the more showy varieties are wisteria, with its clusters of white to purple blos soms; clematis, which has a large flower appearing from early summer until fall; and trumpetcreep-er, with its tropical-looking clusters of big scarlet and orange flowers during late summer.
There is also trumpet honeysuckle, which has clusters of red and yellow perfumed flowers; and climbing hydrangea, with its large white clusters. Some of the annual vines, such as the hyacinth bean which grows on strings and has many flowers, or the scarlet runner bean which has showy flowers, are good for shade, too.
For covering banks and ground where you have difficulty with grass, you might try periwinkle (also called running myrtle), an evergreen which has blue flowers all summer. Another evergreen is achysandra, mentioned elsewhere; and there is moneywort which flattens against the ground.
Some attractive and fragrant-blossoming annuals that you might also consider are: nasturtium; bal-foon vine, which is good to cover fences; cypress vine, with a large number of small star-shaped flowers in orange, red and white, and the familiar morning-glory and moonflower plants.
