Interesting, John, and helpful, thanks for posting. I'd never have guessed that those berries could be a problemLeaves of three,
Beware of me.
The three-leaved summer arrangement has dried up, but these are berries of a mature Poison Ivy Plant. Poison ivy rash is caused by an allergic reaction to an oily resin called urushiol. It's found in poison ivy, poison oak and poison sumac; berries are nasty as well. I am constantly aware of these plants as the rash is very severe and long lasting on me, and can only be controlled with steroid injections.
