Information about poison ivy, oak, sumac and the skin rashes they cause
Virginia creeper is supposed to have 5 leaflets in a group. Normally it does, but occasionally it gets "lazy" and only give out 3. Which is a problem for people trying to distinguish it from poison ivy, which always has the the leaflets.
We have been wondering for years, and still wonder: with so much terrrible poison oak throughout California, why are there no poison oak plant control services?
Those wacky guys at Umar Mycka's The Poison Ivy Horticulturist sent us a real nightmare image of poison ivy taking over the side of a house and reaching for the doorknob!
Here is an example of many California fire fighters running afoul of poison oak while fighting brush fires. You can watch the video, though you will need to work your way through layers of pop-up windows and a long sponsor video before the "real" video.

The ITCHY Project: Poison Ivy Education and Research: The Jelesko laboratory at Virginia Tech is the only academic research lab devoted to Poison Ivy/Oak/Sumac research. The Jelesko lab recently launched the Investigating Toxicodendron Change and Habitat for Years (ITCHY) Project to educate the public about poison ivy science (both what is known and still unknown).
In this 20-second video you can see where visitors to this website come from, at least on June 20. It does change as the season rolls along.
Umar Mycka, that legendary poison ivy warrior, sent me the photo of a massive poison vine creeping up a house.
