Great choice. It looks like you got one with a lot of spots.
I love these Richard Mueller hybrids and watch their flowers go through big color changes usually going from reddish, orangish to almost pale yellow depending on the amount of sun they get. I linked to a photo of my Bl. Sunset Glory ( Bl Richard Mueller X L. purpurata) in the back of the photo showing the younger pink flowers and yellowish older flowers on the same plant.
By the way, I usually train the first few growths to grow straight next to a stake and the subsequent new growths can be tied to them with rubber bands while they are in training. Note how with a rubber band on the new growth tied to the wire tie I can very gradually pull in the young growth without putting too much pressure on it to cause it to snap.
