I saw these "Fried Egg Flowers" at the Fullerton Arboretum yesterday.
I saw them on Ebie's post, from the Main Ingredient, last week and had to get to the arboretum to see them for myself!
These are growing on three sides of this building.
I am not sure why they can be called "Tree Poppies" when they grow as a shrub.
They can be found on hillsides in coastal canyons in Southern California and parts of Mexico.
