Ok, THIS is the last photo I am going to post. This is poison oak on the right and poison ivy on the left, there is almost no difference between this plant and poison ivy, both are 3 leaved, climbers and creepers or a bush with the same climate and habitat conditions. The only difference between this and poison ivy is that the leaves on poison oak are lobed and look a bit more like oak tree leaves compared to ivy. Poison ivy and oak will easily crossbreed creating a rather unpleasant hybrid ivy. Fall foliage of this plant is very similar to poison ivy and Virginia creeper.
