Wisteria (figure A) is a good choice to cover a permanent structure in a garden--if the structure is extremely substantial. Wisteria is very aggressive and has been known to pull down small buildings. Prune plants every winter, cutting back or thinning side shoots from main stems and cutting back to two or three buds the flower-producing spurs that grow from these shoots.
Trumpet vine (Campsis) (figure B) can be grown in full sun or partial shade. It climbs by tendrils and needs some support if grown on a wall.
Honeysuckles (figure C), shrubs and perennial vines in the genus Lonicera, should be pruned after flowering. If honeysuckle becomes overgrown, cut it down to the ground in early spring. This hardy vine requires full sun or partial shade. Avoid L. japonica, or Japanese honeysuckle. Spread readily by birds that eat its berries, the vine is extremely invasive and destroys native plants' habitat.
Kiwi (Actinidia) (figure D) is a deciduous vine that requires full sun or partial shade. Plant in rich soil and provide a sturdy support.
A number of annual vines are well worth planting. Hyacinth bean (Dolichos lablab ) (figure E) and morning glories (Ipomoea) should be direct sown once the soil has warmed in spring. Because the seeds have tough coats, they should be soaked overnight or nicked with a knife before planting. Both thrive in full sun, are quite drought-tolerant once established and have few insect or pest problems.
Clematis prefer full sun on the foliage and cool shade on the roots. To provide shade, plant them among shrubs, and mulch the base of the plant to keep the soil cool. The soil should be fast-draining and rich in organic matter. Water generously, and feed with a balanced fertilizer in spring and fall.
Grapevines (figure F) can be trained on any structure. Fruit is produced on stems formed the previous season. These newer stems have smooth bark; older stems have rough, shaggy bark. Grapes are pruned to limit the amount of fruiting wood, ensuring that the plant doesn't produce too much fruit and that the fruit is of good quality. Their spectacular fall color is a bonus. Most grapes require full sun and a rich, fast-draining neutral soil. No fertilizer is needed.
