I found an excellent post on Poison Ivy and how it can teach us awareness.
Poison ivy doesn’t tolerate such behavior. She asks us to be present with each moment. She asks us to observe, to pay attention, to be aware. If we are aware, we can avoid the more intense lesson she offers: that of the “poison ivy” contact dermatitis we are all so familiar with. That poison ivy is awareness medicine was a teaching was first given to me years ago by my herbal mentor, Jim McDonald, and it began helping me begin to see poison ivy in a new light. When you start observing and paying attention for Poison Ivy, it changes the way you interact with the world. Link
This comes from The Druids Garden Blog which is always a good read!
Poison Ivy’s climbing form is particularly adept at shapeshifting and in enforcing this lesson. Her climbing vine is distinct, but can often blend right into the wood of a tree (or be climbing up the opposite side of the tree and you don’t see it). Her leaves, then, literally blend into the leaves of whatever tree she is climbing. This means you need to not only keep an eye on the ground, but also an eye above you. I’ve had numerous occasions where I failed to look up and had a poison ivy branch brush my face. Fall brings yet another lesson from her climbing form. These higher branches have leaves that turn a beautiful red, and then, as leaves are apt to do, drop. So if you are walking around barefoot, or even deciding to rake leaves and jump in them, you can be in for a surprise a day or two later. Knowing where these vines grow, then, is part of the knowledge of the natural landscape that poison ivy teaches. Link
