Growth looks lush. The plant looks very happy. It sounds like you're taking very good care of it. Not sure I've ever had a hybrid tea that looked that good by the end of summer!
It looks to me like the rose in the first photo might be making a little bud at the tippy tip of the left most cane. Perhaps it will bloom in fall.
Is there any hope that you'll be able to move your large planter into a cool basement for the winter? Or that you'd be able to heap enough mulch on it to keep the rose from freezing too severely in deep winter? I ask because many of my best roses don't hit their stride until year 3 or 4 or 5, and I'd like to be able to suggest that Chrysler Imperial will improve with age.
