I don't have good pictures of most of my "M"s, but here are a few:
One of my few doubles, and it is fairly reliable as a double. (Sometimes the first few flowers might be single, but most years, not.)
An oldie but goodie. Love the color. Wouldn't mind an "improved" version of this (my idea of "improvements", of course!).
Beautiful on the days when it opens well (it is not in this image); the flowers are maybe 30% polymerous here. (Most (if not all) of the registered polymerous plants that I have acquired have not performed to spec, here. I suspect partly it is a matter of shade, partly of water, but I suspect that something else climate-wise is involved, as this has been true in two gardens over many different cultivars and with differing amounts of water and shade. I've been trying to use 'Magical Indeed' in my pollen dabbing, but it has been a reluctant pod parent for me, and thus far I have not gotten any polymerous seedlings from it.)
