Other trees are still waiting. The horribly situated Amur Corktrees that line a nearby block are still showing naught but their scraggly skeleton. The walnuts are still patiently waiting. But the cherries and pears are in full bloom, and the dogwoods are not far behind.
The edges are where interesting things happen. The edges between forest and glade, lake and shore, but also between winter and spring. So get out there and look at the trees. We all get a fixed number of springs to enjoy in our life time . Don't let this one go by unnoticed.

A silver maple's developing samaras. Note the sharp angle between the two wings, the obvious asymmetry of some pairs, and the vague tadpole shape of the longer wings.
The tassels and new leaves of a willow oak.
Nothing beats a redbud for early spring knock-you-on-your-butt beauty.
