An espalier is a plant trained to grow flat against a wall, fence, or trellis. Developed by the Romans, they were popular in Middle Age Europe as a source of fruit in castles and monasteries because they could be grown against the keep's stone walls leaving open space unencumbered. Now they are an excellent choice for apartment and condo dwellers with small yards. For larger yards espaliers can be used as a decorative feature, to provide shade or to increase the variety of trees under cultivation. University of Florida PDF detailing the technique.
