We found some 'Egg Yolk' flowers out there...

Egg Yolk Rose
Isn't that neat? I remember something like the Egg Yolk Flower on Crown Valley Parkway in Laguna Niguel, CA during the spring.
I may have some photographs from the Laguna Niguel Botanical Garden! If I find them, I'll come back and post them here too! :)
