Hedges, both clipped and unclipped, are often used as ornament in the layout of gardens. Typical woody plants for clipped hedges include privet, hawthorn, beech, yew, leyland cypress, hemlock, arborvitae, barberry, box, holly, oleander, lavender, among others. An early 20th-century fashion was for tapestry hedges, using a mix of golden, green and glaucous dwarf conifers, or beech and copper beech. Unclipped hedges take up more space, generally at a premium in modern gardens, but compensate by flowering. "Rosa multiflora" is widely used as a dense hedge along the central reservation of dual-carriageway roads, such as parkways in the United States. In mild climates, more exotic flowering hedges are formed, using "Ceanothus", "Hibiscus", "Camellia", orange jessamine ("Murraya paniculata"),[http://weeds.brisbane.qld.gov.au/weeds/mock-orange] or lillypilly ("Syzygium" species).
