  According to Waldecks, a hedge is a row of trees or shrubs of the same species grown closely together to form a barrier, boundary or wall of foliage and flowers. Due to the conditions, most hedges growing in Western Australia are tolerant to the sun, grow in sandy, clay or alkaline soil, require little water and are drought tolerant.
  
  

Rosemary Hedge

• Rosemary, or rosmarinus officinalis, is best grown in south and western Australia, as the hedge prefers hot, dry conditions and requires limited water. The hedge grows to be 4 to 6 feet tall and 7 to 8 feet wide. The foliage is thin, lance-like, grayish-green and aromatic. The hedge blooms from late winter into early spring with small white to blue-colored flowers scattered throughout the hedge. The hedge is best planted in full to partial sun conditions, with alkaline soil, and requires little care.
  
  

English Box Hedge

• English box hedge, or buxus sempervirens, is a common evergreen hedge that can be planted in Western Australia. The hedge can grow to be 15 to 20 feet wide and tall. The dark green, oval-shaped leaves are 1/2 inch to 1 inch long and half that length wide. They look leathery in their appearance. The hedge blooms in late spring, with small white to cream-colored, nonshowy, fragrant flowers. The hedge grows best in full to light sun conditions, dislikes the cold and wind, and unlike other common western Australian hedges, prefers moist soil.
