I was surprised to find these growing under a tree at Brookhaven College. I am not sure if they are cultivated, as they seem an unlikely find. They are growing under a tree where the mowers do not reach, but nothing to indicate they would be cultivated. They are not close to the pollinator garden and this species does not appear to be planted there.
Not familiar with this species and using iNat's top guess + a review of what has been documented at this campus before
