Lancelot "Capability" Brown, landscaper to the rich and famous in 18th-century England, died in 1783. He advocated vistas that were "simple, uncluttered and restrained."

A mixed border is usually a defined space with a mix of perennials, annuals, shrubs, bulbs, and/or grasses with a walk, or path, in front and a wall or a fence behind as a backdrop. A mix of plants of different varieties ensures an extended period of interest.
