Does poison sumac have an aroma?
Lebanon County Pennsylvania poison sumac
I couldn't find any reference to an aroma for poison sumac. However, here is some information that may help you identify your plant. Poison sumac is more prevalent
in the Southern Mid-Atlantic.
There is an invasive plant which looks very similar called Tree of Heaven. The easiest way to know if it is this undesirable plant is to pull a leaf, crush it and smell it. If it smells like rotten peanut butter, it's Tree of Heaven which spreads aggressively.
Poison Sumac is found throughout the southern states east of the Mississippi River but limited in distribution to very moist areas; in bogs, pocosins, wet pine barrens, and stream borders.
