Thank you!
Here are several versions in commerce. I planted one in a “kindergarden” a few years ago, always in bloom and big, but more pink than purple. It sets hips sometimes, only few, but I opened them and they contained a few seeds, about four per hip. But nothing germinated. I had two seedlings from RDV a few years ago, used pollen of them on Florence Delattre, Wonnhalde and Rosana (they are in HMF). But they are lazy bloomers and growers.
The source of my Reine des Violettes was a store called Lowes. The pistils on mine look normal. Last year was my first year using it, so I don’t know much about it yet. I put mixed china, tea, and polyantha pollen on it and got an average of 6.75 full size seeds per hip. Hip set seemed about average, although I didn’t count that. My RdV makes some pollen, although the quantity is a bit less than average. I put it on Clotilde Soupert and it set well. I haven’t tried to germinate them yet.
