You will love this shrub, HamiltonSquare. For me it blooms almost year-round, except during the hottest days in summer, when water is very scarce here.
You folks familiar with and growing this plant should add the info to the ATP database. I had to do a Google search to find info after seeing it here. It's so much more convenient to just go to the ATP database . I know. I admit I'm inherently lazy .
I received mine as a small plant (some 20cm) as a present when I purchased other plants. That was 3 or maybe 4 years ago. The plant has always been in a pot and has grown to app. 1m and filled in to the sides.
