One of the more undervalued arts in the world today is the shaping of living plants. Topiary is the art of grooming a bush or tree into a particular shape. It takes many hours of labor and trimming to accomplish this feat. A plant continues to grow during this process and must be monitored and trimmed on a regular basis. Bonsai trees are another form of living art. They are miniature-sized trees that are kept trimmed from the taproot on up. Each one is shaped as it grows to form a living piece of artwork. These trees require attention and care to achieve their beautiful forms.
