This is a Rhododendron plant. It has alot of history in the Appalachian Mountains, and even with stories of the plant in Greek history. "Mad Honey" was consumed and gave soldiers odd behavior during the march of Ten Thousand in 401 BC. As its reported the honey made from Azaleas and Rhododendrons is slightly hallucinogenic. But will also make you crap yourself, so dont try it.

In Ultraviolet fluorescence photography experiment #4 I used an Azalea plant. They are differentiated from "true" rhododendrons by having only 5 anthers per each flower.
Here is my Azalea photo series: https://steemit.com/photography/@freedomcoin/ultraviolet-fluorescence-photography-experiment-4
The stems of the flower have an orange yellow color to them, usually green in normal light.
Return of the thumb!
I like how the anthers slightly glow in the bottom flower, that is what the pollen sacks are attached to.
Lastly the two photos in ultraviolet and then normal light, for reference.
