Where did you get it? You can do a data base search based on certain qualities, such a WHITE beard - purple standards and falls. One similar historic is Rose Marie by Cayeux. You can also check the photo gallery at historiciris.org
I got it from a friend whose house was foreclosed. I am nurturing many plants to hopefully give back one day when my friend is "back on his feet again." He didn't know what it was. It was there when he bought the place. Thanks for the tip. I'll try a search.
