Mother in law roses

This is a rose bush we started from a cutting of one of my Mothers bushes over 40 years ago.. We have lived in many houses over those years and every time we moved on we took a cutting with us and the flower is still with us.  We call it the mother in law because it was a present from my mother to my wife.  And, it always blooms on Mothers Day.  Always.  It is just an old flora bunda but it has a history with us.
