We visited Smoky Mountains National Park during a warm April week when the leaves were just starting to show in the trees and spring wildflowers were beginning to bloom. Here is a spring view of the famous Great Smoky Mountains from the Campbell Overlook when green was appearing on the lower trees but the higher elevations were still bare.
Yosemite National Park's Mariposa Grove of redwood trees also has other species of trees. Here's a wallpaper that shows beautiful, blooming dogwood up against a background of redwood trees.
This tree of cherry blossoms was beautiful against a bright blue sky. Fortunately or unfortunately, the bees really loved it too! Here's a wallpaper with a bunch of cherry blossoms against a blue sky.
