Land Plants - invasive

Old Man's Beard (Clematis vitalba) on Aug 10, 2009

Submitter does not have a specimen
EDRR Status: Local expert notified

Description of specimen

the plant is Clematis vitalba, Old Man's Beard. It is on your B list. It is common in Multnomah county, however on the description in the Council information it is not noted to be in Wheeler county.
There are small growths that are along the stream next to the highway. It looks like it is in early stages of invasion and only riparian.


This is not on the A list, but could it be worth attention in areas it has just invaded east of the Cascades?

Here is an e-mail that I recieved from Hoot:


I went and collected a sample from the location in the hotline report and I worked on keying the plant out all afternoon. Even though I could only find limited pictures of any clematis species, I believe it is a native clematis species which one I do not know. In addition my observation to and from work the last day I saw several clematis plants growing all over Wheeler County that makes my believer further that it is native.

Hope this helps,
