WOW! that is just beatuiful! We have one the same color and it blooms on cue too..
It is very old, more than 30 years but the main part of the plant died this past summer. I was able to salvage a branch, as they root so easily and with just a couple of small branches it is blooming up a storm! I am so glad it is happy again. I can't wait for it to get as big as yours smileys/smile.gif
We also have a bright pink one that is a bit more than 12 years old but it blooms at Thanksgiving. Still lovely to enjoy.
