Poison Ivy in Brooklyn, New York City

You don't usually think of poison ivy as a city plant, but it shows up in lots of cities; here in fabulous Brooklyn.

You won't see much poison ivy on 5th Avenue, or even in Central Park, where it could grow happily, but is kept out. But get into any backyard in any borough with weeds, or along the parkways and you will find tons of it.

Also seen in massive growth in vacant lots in Cincinnatti.
