There are several different types of living sculpture techniques, including topiary (prune plants or train them over frames), sod works (create sculptures using soil and grass or moss), tree shaping (growing designs with living trees) and mowing and crop art (create patterns or pictures with plants or in lawns).
Although sculpting plants isn’t a new idea (bonsai or topiary have long historical traditions), its recent rediscovery by artists, horticulturalists, gardeners, and young people has given living sculpture an innovative popularity.
One of the older and more familiar kinds of living sculpture, topiary is the art of growing dense, leafy plants and pruning them into a form, or training them over a frame, to create a three-dimensional object.
These works may be created on waste sites, and may draw attention to land reclamation and urban restoration efforts.
Recent earth artists have worked with soil, sod, or moss to create forms that may be intimate and small, or large and multi-acre.
[1] The practice is commonly used to accelerate and increase production in fruit-bearing trees and also to decorate flat exterior walls while conserving space.
There are a few different methods[4] to create shaped trees, which share a common heritage with other artistic horticultural and agricultural practices, such as pleaching, bonsai, espalier, and topiary, and using some of the similar techniques.
Tree shaping has been practiced for at least several hundred years, as demonstrated by the living root bridges built and maintained by the Khasi people of India.
