Boxwood is the most common type of bush used for topiaries. Boxwoods, or English boxwood, in particular, are suitable because they’re easier to prune, train and shape. They have tiny leaves, which can be shaped with precision and in streamlined cuts. Some bushes don’t do well with close shearing, but English boxwood shrubs thrive with it. Pruning keeps boxwoods healthy, and the structure of this plant makes it more manageable to achieve a crisply groomed appearance. However, yew can also be used, while evergreens are the top choice for year-round topiaries.
