It is now safe and unlikely to be killed willy-nilly.
The female of the species produces the ‘cones’ that are used to flavour beer. If you look around the Creek area you will find a female somewhere. It’s a bine rather than a vine though the leaves are similar in shape to those of a grapevine.
It will smother young trees and can clear areas of other vegetation if allowed.
It grows tremendously during the growing season and dies back to the roots in winter and starts growing from the base again the following spring. It is relentless.
