I have had 'Heartbeat of Heaven' for 4 years and like it very much. I have found its color can vary quite a bit (as you can see from the several pictures from different growers here on this forum), but that is one of the things I like about it!
I have not kept any record of branching, bud count, etc. but as I recall it blooms for quite a long time.
I took above photo because it showed a bloom with more yellow than usual and just looked so pretty!
