This flower is on the south side of my home, which is the warmest site, of course. What is more interesting to me, is that just a few weeks ago, I moved and separated a number of daffodils, including this one. They had been inside a deer-proof fence, which is unnecessary for anything in the narcissus family. When I noticed the leaves emerging from the ground, there was a warmer day that I took a shovel and decided to give some daffodils a new home. The weather was cool and wet enough that they did not mind the move.
Now to remember after blooming, and when the leaves have died down, to take a shovel to the daffodils that did not get moved and separated this winter. There are lots of them to be dealt with.
