Dear Candace,
congratulations.
It is really nice to see this beautiful hybrid which I named many years ago for the village where I live, Mietenkam a part of Grassau sout of Munic. My plant needs around 8 years to come in flower, but 3 year later i lost it.
What a nice surprise after such a long wait! Very nice flower! Maybe now that it's decided to bloom once, future bloomings won't be so few and far between? They are really nice blooms though, so that one may be worth it's space even with reluctant blooms.
