Here's a great solution for a blank wall: espalier, the art of growing a plant along a flat surface. It may look costly and complicated, but it isn't. This project is something you can do in a weekend. Perhaps you haven't tried growing vines because they seem unpredictable. This method helps you control that. Choose the right one, and you'll get a lot of coverage for the money.
Decide on a Style
First, select a pattern. The technique of espalier was originally used to produce a lot of fruit in a small space. Though you may not be growing fruit, you can still borrow from the method. Choose from one of the classic designs below, or create your own.
Select a vine that climbs by twining or by tendrils and has small to medium leaves. The scale of the vine should work with the pattern you select. Confederate jasmine (Trachelospermum jasminoides), with its neat, dark green leaves and fragrant flowers, is perfect for the diamond pattern. Carolina jessamine (Gelsemium sempervirens) and crossvine (Bignonia capreolata) work for large-scale projects and open patterns such as the fan or candelabra.
Ivy is a tempting choice because of its beautiful foliage and fast growth (once established). However, it climbs by aerial roots that can attach to walls and turn into a maintenance nightmare if left unattended. If you do use ivy, choose one of the variegated selections, which tend to be slower growing.
