What is espalier?
Espalier is a plant-shaping method to grow woody plants in one plane on a permanent framework, often in an artistic design. Woody plants are those that grow year after year above ground and have bark. In temperate climates, the espaliered plant is often fruit bearing, such as trees of apple, pear, plum, or cherry. But there are also Gingko espaliers, Magnolias in elegant forms, and evergreens in an espaliered trellis design.
