What are you feeding it Paul???. Lol
Tell us, how warm does this plant grow? And in what light level? You are doing a nice job with it, that's for sure! Mine blasted its only bud and has now been repotted and is gaining new growth but no sign of next year's bloom possibilities. I now have the clump in a basket. We shall see!
Does druryi x armeniacum exist? I can't find anything on the cross, google must be broken.
