Ivy is a very common plant in gardens. It can be used as a ground cover, but usually is grown as a vine-like creeper up walls and fences. Many older buildings around the world have ivy up the walls, which was once considered quaint but now often it gets removed because it can cause problems to the buildings through the roots penetrating cracks or joints in walls. It is considered a weed because it often becomes too aggressive within gardens, and also it makes its way into blocks of native bush where it causes havoc by growing up trees and smothering them with their leaves.
