The weeping willow (Salix babylonica) is perhaps one of the most common trees to see in parks with ponds full of ducks and geese. I have fond memories of standing on the edge of a pond feeding the ducks and occasionally a large swan with a majestic Weeping Willow tree on a small island as the backdrop. The image above is of a pond in Laurelhurst park in Portland, Oregon. The tall trees behind the Weeping Willow are Giant Sequoias.
The image below is of a Weeping Willow in early spring before the green leaves appear. The smaller branches have a orange-yellow color that gives the Weeping Willow an interesting appearance even in Winter when it has no leaves. This particular tree is located in a park on the north side of Spokane Washington.
The image below is of the new leaf buds along the long, thin "weeping" branches before the leaves form.
The bark of the Weeping willow is fairly thick and rough with a sort of stretch pattern that can be seen in the picture below.
Another "weeping" tree that I like is the Weeping Bottlebrush tree.
