Topiary is the horticultural practice of shaping perennial plants by trimming foliage and twigs to specific shapes, either geometrical or in sculpture form. This is known as ornamental landscaping and dates back to Roman times, where hedges and shrubs would be shaped into figures of animals, ciphers, and obelisks.
The best plants to use for topiaries would consist of woody evergreens that have small leaves and are known to have dense foliage that grows compactly together. These would include:
Buxus sempervirens
Duranta ‘Sheena’s Gold’
Nandina domestica
Syzygium Paniculatum
Viburnum tinus
Abelia
Modern-day topiaries are made easier for the untrained shears, with wire cages that are already shaped, which helps guide the plant into the desired shape. This also makes trimming the hedge easier and less time-consuming.
The shapes and sizes of a topiary is completely up to the designers imagination and desire!
