Circle around our street tree, May 19. The yellows had been opening up for about a week at that point.
I think I also have a few whites near the birch tree that haven't opened yet. They were planted there when the tree was smaller, and there was no shrub bed nearby, so they are kind of hidden. I'm going to be a busy plant lady doing divisions this summer, I think.
As always, click the photographs for larger views.
