Seven Sisters?

I doubt it.  This is just one of the root stock roses that something nicer was grafted on...Aunt May was not a gardener, and just tended what came up.  Many of the tea roses and other hybrids were nurtured long after the nice rose died, But then, I can remember Aunt May with them, which is very desirable.  Still pretty if not a great name.  Mom always wanted me to rescue the Seven Sisters that she remembered as a child, but this was where she remembered the bush to be.  Long gone I guess.
