Poison Ivy In Ice

poison ivy in ice

Normally you would not expect to see poison ivy growing out of icy swamp water.

But all these vines, from the big 2-incher to the tiny 1/4 incher are all poison ivy.

During the summer, this wetland has a lower water table, so the poison ivy grows in damp ground, but not from open water. I have NEVER seen poison ivy growing out of open water except when a river floods. 

Poison ivy is very adaptable but has limits: it doesn't grow in the desert and it doesn't grow from open water.

By contrast, Pacific Poison Oak can grow in near-desert conditions in California. And poison sumac almost always grows with its roots in open water or very wet mud.
