We bought a house five years ago with multiple noid (to me) rhododendrons and azaleas. One caught my eye blooming this year because the flowers reminded me of a rose. Maybe it just has double flowers? I can't find anything quite like it in PlantFiles.
It's relatively short at about 24-30 inches high, growing in dappled sun/shade, and bloomed the second to third weeks of May. I'm in zone 6A in Michigan.
