Yellow flower greet in Spring time

This is the first flower we have seen inside our community since the winter time. The flower was so attractive to the eyes because surrounding it was only plant trunk or green plant. We don't really know what is the name of the flower. So nice to see that spring time is coming....

Taking Ethan's photo with the yellow flower while on the way to library

The trees are starting to grow back their leaves. Couldn't see it clearly in the photo yet
