A reasonably large woody climber that may reach a height of 15 m or more when well supported. Its common name is derived from the garlic-like aroma emitted when the leaves are crushed. However, this should not be allowed to detract from this otherwise appealing plant. Its mauve flowers are also scented, but not strong enough to be offensive. This climber prefers to be grown over a supporting structure like a pergola, arch or fence.
