About

Published on Jul 9, 2012

I have to admit not being able to distinguish between various wild roses. I think we have both Prickly Rose (Rosa acicularis) and Nootka Rose (Rosa nutkana) here. If anyone can help me identify them with more certainty, I would greatly appreciate it and change the description here!
