Topiary is the art of shaping plants, particularly shrubs and trees, into decorative forms. This practice often involves trimming and pruning to create intricate designs, such as animals, geometric shapes, or even abstract forms. Common plants used for topiary include boxwood, holly, and yew due to their dense foliage and ability to withstand regular clipping. Historically, topiary dates back to ancient Roman gardens, where it was used to enhance the beauty of outdoor spaces. Today, topiary can be found in public gardens, private landscapes, and even as indoor decorations. It remains a popular way to add artistic flair to gardens and parks.
