20th Century
American portable style topiary was introduced to Disneyland around 1962. Walt Disney helped bring this new medium into being - wishing to recreate his cartoon characters throughout his theme park in the form of landscape shrubbery. This style of topiary is based on a suitably shaped steel wire frame through which the plants eventually extend as they grow. The frame, which remains as a permanent trimming guide, may be either stuffed with sphagnum moss and then planted, or placed around shrubbery. The sculpture slowly transforms into a permanent topiary as the plants fill in the frame. This style has led to imaginative displays and festivals throughout the Disney resorts and parks, and mosaiculture (multiple types and styles of plants creating a mosaic, living sculpture) worldwide includes the impressive display at the 2008 Summer Olympics in China. Living corporate logos along roadsides, green roof softscapes and living walls that biofilter air are offshoots of this technology.
Artificial topiary is another off-shoot similar to the concept of artificial Christmas trees. This topiary mimics the style of living versions and is often used to supply indoor greenery for home or office decoration. Patents are issued for the style, design, and construction methodology of different types of topiary trees.
