10. Light effects
Most gardens, influenced by the plants and architecture around them, greet the same patterns of light and shadow each day. Here, Robert deliberately controlled the elements through his use of birch trees and the construction of the cloister walk and circular canopy, and chose his plant material accordingly. Beneath the birch at the front of the garden, groundcovers and textural herbaceous plantings for semi-shade were selected, says Robert. Splashes of mostly white flowers like peonies, foxgloves and heucherellas create spots of light in a predominantly cool palette against the background of the dark timber pergola.
