Cultivated. Hanging branches 5 feet long!
Mated Pair in this image. I discovered this previously unknown WH White colony last year at this time. Had 2 individuals last year & 4 this year when caught a pair mating
Apparently wild. Growing on the banks of Lake Whitney, in the woods.
In the Yale Experimental Watershed. Quite a large population. Doesn't show up in any of the species lists put out by Yale for the watershed. Maybe they didn't know what it was?
Pipilio cresphontes
3.5-5.5 inches
Could this be butternut? Nuts are very sticky.
