Do you recognise the plant from this detail?
At this season there is a good chance you have it at home!
I say Euphorbia pulcherrima! That was too easy a hint, Frank!
I never looked that closely, and don't have one in the house at this time, but based on your clue, it is likely Poinsett's euphorbia.
Drat! Beaten again by the succulent goddess!
Hey! I like that name!
