What is this plant
We was kayaking in a freshwater swamp when we came upon
a woody shrub which from a distance appeared like Joe Pye
Weed but on closer observation the 'flowers' were large clusters of dark pink small berries hanging off the tops
of the branches. Thought maybe it was poison sumac but it
wasn't. The bushes were at least 6 feet tall. Unfortunately,
we didn't get a photo of it. Does anyone have a guess?
