"

A classy vine with shiny green leaves and large white panicles of blooms in late summer. It needs to be supported and is slow to become established. It has cinnamon coloured bark that exfoliates, providing winter interest. This is a great vine for walls and fences. It is slow growing but hardy. Also good for massing or filling large areas. Look for interesting shadows created by the deep foliage.
