Old man's beard in New Zealand

Old man's beard (''Clematis vitalba'') is an invasive plant in New Zealand that has an impact on indigenous biodiversity. It is declared an unwanted organism under the Biosecurity Act 1993 which means it cannot be sold, distributed or propagated.
==Spread==
Old man's beard was introduced into New Zealand as an ornamental plant some time before 1922 and the Department of Conservation and other government organisations now spend millions of dollars on its control.
The seeds are wind-borne on a fluffy boll and can remain on the vine over the winter months. The seeds are most likely to germinate on disturbed ground where the light level is more than 5% of full sunlight. It is more common outside undisturbed forests on forest and stream margins and forest gaps.
