Oh Wow! Looks more like a pinwheel or a child's toy! Most unusual and I have no idea what it is called either, but I sure am glad you bought and photographed it for us to see.
Wow! How unusual and pretty. Upon close examination and after much thought I'm sure this is the Red Do-nut species of Dunkinville!!:):) LOL! Either way, I can see that little spider likes it:):) Nice closeup Eleanor:)
