Old Man’s Beard, also known as Clematis vitalba is a vigorous vine that grows up to 10 metres in a single year. It grows rapidy, forming dense layers and damages forests by smothering seedlings and suppressing canopy tree growth. This can eventually lead to large scale habitat loss. Tolerant of cold, moderate shade, damp, wind, salt, most soil types, and damage it is a major pest weed in New Zealand.
