Harmless Sumac vs Poison Ivy

You may see both sumac and poison ivy along many roads, often right by the guard rails.

But the sumac you see along the highways is almost always either smooth sumac or staghorn (fuzzy) sumac, both harmless.

But the poison ivy that grows in astounding frequency along so many roads is not harmless! It can ruin your summer.

Real poison sumac is only found in very wet areas.

But real poison ivy is along every road, every path, every field, every vacant lot east of the Rocky Mountains, specially in the east of the US.
