This is plectranthus ecklonii. It needs shade, but I didn't think these would flower in the very dense shade of a Mulberry tree. They're doing just fine. The pics don't show how dark it is under there. The few I've planted where they get some sun (midday now that a large overhanging Hopseed Bush died) are not doing so well. These also come in a white flowered version which I don't have, need to see about that!
I could be wrong...
