I pinched a snip of this from Bernie and Jeanette's (across-the-road neighbours) a few weeks ago when they were on holiday. It looked so cute blossoming under the blood orange tree. The pink flower is a gorgeous tinge. I put it near the front gate, and it seems to be doing ok in the semi-shade there.
These photos really do not show it's true beauty. I will try photoing it again on the weekend. The pink of the flower is really much more intense than this. I wish I knew the name of this plant.
