I loved catching this image on my Climbing Pinkie rose arbor...after the rain, a hummingbird with two butterflies that kept circling it. Pretty zen afternoon...

Does anyone know what the red berried vine is (it's a volunteer) that is growing in with my pinkies now? At first I thought it was poison ivy, but as you can see, the leaves are rather heart shaped, and not growing in threes. I'd love to know what is growing in with my pinkies now!
