What Is Your Name

I stopped at a yard sale a year or two ago and this plant was shared with me.
I split the plants in the pot and put in several locations and they
have done wonderful.

Another late bloomer and no bugs or disease has attacked it.
It has really spread and that is what the owner shared it would do
Is not blooming at the moment but I am expecting that in the
next week or two.

Will be nice to have something blooming in July.

So this Fall will plant it in several places among my gardens and my put some
in the woods....

Anyone know the name ?
