Glad to see this thread revived. I believe I separated my 'Peach Magnolia' a few years ago to give some to a friend and it really took a hit. Looking forward to more blooms this year. It is not a prolific bloomer in my garden and the branching isn't the greatest, but it gets some shade so maybe that is why.
I am not 'into' doubles very much, but I just love the color of PM. I bought it in 2004 for $7, the year I found out there were daylilies other than Stella de Oro.
This picture was taken in 2009 and I just love the way the ninebark accentuates the color of PM. I don't have the ninebark anymore and PM got moved a few feet away years ago.
