It has a moderate growth rate and a generally upright, oval to rounded form.

Cuttings should be taken from the current season's growth, and should be approximately 6 inches long. The cuttings should be taken from healthy, undamaged branches, and should have a sharp, clean cut at the base. The cuttings should be placed in a moistened media such as perlite, vermiculite, or sand. The media should be kept moist, but not wet, and the cuttings should be placed in a well-ventilated area out of direct sunlight. Rooting will usually occur within 4-8 weeks.
