It's daffodil time in Kentucky
Floridata's daffodil page says that common names for Narcissus spp. include daffodil, narcissus, jonquil, Lent lily, Easter flower, and butter-cup. In fact, there are so many different sorts of Narcissus that botanists divide them into 13 different categories.
To me, light-colored daffodils (like those in the photo) are "jonquils." I have no scientific reason for giving them that name. It's just my way of distinguishing them from the yellow-blooming ones which I call "daffodils."
Here in Kentucky, many people refer to the little old-time yellow daffodils as "buttercups." In early spring, buttercups pop up and bloom in many places where the houses have been gone for untold years. They're a memorial to gardeners whom we never knew.
