Forsythia blooms.
I first saw daffodils blooming as far north as my house on Friday, but all the open ones were right by house foundations. Perhaps it's slightly warmer there... anyhow, I don't have any daffodils planted right by my foundation, and didn't really want to get that close to someone's house to take a picture for fear they'd think I was fishy and call the police. SO I waited until today, when I found an open one farther from a home.
Look how yellow the pussy willow pollen! And speaking of willows, the weeping willow catkins are starting to appear.
So it's a yellow day!
