Hibiscus

I caught a glimpse of this flower on a potted plant we keep on the deck, just as the late light was shining from the petals.  So I went to get the camera before anything changed.  We've had this plant a long time, as originally we bought it for my mother.  She had it for many years in her conservatory until she moved into a retirement village about 6 years ago.  We've had it ever since.  I prune it regularly to keep it small enough for a pot.
