I have had this for at least 8 years and right now is over 10 feet tall. It bloomed last summer about this time and has not stopped since, even blooming during our mild winter, this is the most blooms I have ever had at one time. In years past I have topped it and added those cuttings to the large pot I have this in, now I have it against a fence and will let it grow as tall as it wants until it bends over from the weight.
