As we drive through forests and meadows here in northern CA and southern OR in spring, one type of tree we see often is a dogwood.  In some places they line the roads and are all in bloom.

They are really pretty trees and the white flowers contrast so nicely with the shades of green of the other trees.

We see these trees at altitudes of between 3000 and 4500 feet up, and they only bloom if they are in the sunlight.

We also took close-up shots of another little wildflower and a manzanita in bloom:
