I give it a hard trimming in the spring (March usually) I think it starts getting flowers around late May or June and they can last all the way till we start getting cold nights, I had flowers on it around Thanksgiving. I had mine in a huge container for about five years and it became root bound so I put it in the ground last spring, it has looked much better since. I completely lost one over ten years ago that was pretty established when we went down to low 20's for a week long two years in a row. They do like morning or late sun and seem to prefer some dappled sun in the hot part of the day. They are zone 10a and above, but I see some really fine looking trees around here, usually up close to a house.
