White and orange daffodil, taken by my wife
Everyone else seems to have posted daffodil (Narcissus) flower photos, so I'm posting one, too, finally. Since I'm not supposed to bend down yet, I'm posting one taken by my wife, bless her, in her flower garden.
The Wikipedia article on this plant tells us that the (in this plant) orange structure is a corona, and is not the petals.
The plants have many common names, including daffodil, jonquil, Narcissus, and buttercup, and, no doubt, several others, just in English.
