I hope the folks that need to close this gate every evening realize that it is sitting right inside a nice garland of poison ivy.

I once got one of the strangest phone calls of my life, and it was because of this website.
A fellow explained that he had a question about poison ivy and my answer might determine if he spent the rest of his life in prison.

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.
Because of vastly increased CO2 in the atmosphere, poison ivy is growing larger (and more potent).

A viewer sent in this photo of a poison ivy (or possibly poison oak) vine.
What is striking about this image is how the leaves of three come off the main stem clearly alternating left and right. You rarely get such a clear view of how this works since the leaves usually hide the stems.

This photo was sent in by a viewer who wanted to know for sure if this monster was poison ivy.
The answer is... YES IT IS POISON IVY!!!

This is a photo of a poison ivy vine that was chainsawed along with the tree that it was climbing upon.

Here we have two vines that are constantly mistaken for each other, and for good reason: they often grow side by side, or even intertwined.
On the left are two 5-leaflet Virginia creeper leaves, coming from a thin vine.

I had a conversation with the fellow who runs one of America's leading poison ivy control services.
He grew up very much an outdoor kid, had constant contact with poison ivy, while hunting, fishing and just generally being an All-American kid.

It has been a cold, late spring up here in New England, but today will reach the mid 80s, so plants will be exploding into full leaf.

It has been an absolute rule for over a century: "Leaves of three, let them be."
Poison ivy has only three leaves (actually leaflets) in a group. And that is still true about 99.9999% of the time.
