I had Doris that I bought from Bluestone Perennials 4 or 5 years ago. I wanted to grow it because I thought it was lovely, and Doris was my mom's name and at that time, she had recently passed away. It only came back for a couple of years, I was never able to get any seeds from it to germinate, and the last two years there's been no signs of it. I'd love to try it again, if I could find it.
This is my Doris, from 2008.
