It grew that big in a pot??? Wow. Chrysler Imperial has never topped 4' in all the years I've grown one.
I thought of another non-blooming possibility to add to the list: maybe deer or other animals are eating the buds?
Mine bloom much better after I threaten them. Maybe non bloomers are just happy as foliage plants?
I have 3 sets of rose pairs that came about because I threatened the original by planting its replacement next to it. The wimpy original then sprang to life. The only reason i can think of is I may have watered that area more after planting #2.
