This is another hand me down. This one comes from my great aunt who will be 102 on July 1st! Yikes!!! Anyhow its a very reliable plant and it comes back every year. I have had it at least 18 years here in my garden. Not sure how long its been around in hers. I do not know what the name of it is. It has a pretty white flower tinged in a purple-ish color.
