Every so often you may see this sort of strange growth on a poison ivy vine. We sent the photo off to poison ivy scientist John Jelesko and he reports as follows:
Poison ivy loves roadsides. It loves the sunlight. Birds drop the seeds there, often while sitting on power lines overhead.
We often see poison ivy growing over guard rails, but this example was particularly spectactular.

I once got one of the strangest phone calls of my life, and it was because of this website.

This photo was sent by a viewer. And this might be the largest poison ivy leaf we have ever seen! Could be 6 x 8 inches, which is enormous.
