I received this in 2017 and it has multiplied well. The blooms are large and the 35" scapes lean a little. I had it in an area of my garden that is tight for space, so have moved it to an area where it can have more space to shine and where I can tie up the scapes if needed. I have never seen rust on it.
I have not counted branching and bud count, but here is a picture of it.
I would describe my clump as kind of messy, with scapes leaning every which way. Another reason that I moved it to give it space of its own is because even though the blooms are large, the soft pink color is demure and tends not to stand out.
I have not seen a bad bloom on it. Each one is beautiful!
