I bought this "mystery" plant from a local gardening club at an outdoor festival in Pickens, S.C. The man who donated it to the sale did not place a name tag on it, and was not present to tell me what it was.
It has been growing in our yard in Georgia for nearly four years and blooms the most delicate clusters of white flowers in late spring (it is presently blooming).
I would love to know what it is. Can you help?
