A wonderful flower.
Huernia (Huernia zebrina)
Nancyanne: is this plant commonly named "Life Saver"? Just recently, I saw one and it was identical to yours only no one knew the Latin binomial. Thanks in advance for you help.
HI Docturf - I've never heard that nickname, but the central, circular part does certainly look like a life saver. About the same size, and looks like shiny plastic. Always a treat when this blooms.
