Visualize the willow.  The Corkscrew Willow is a fast-growing tree that is a graceful, weeping variety that will eventually mature to a height of 30 feet. The branch structure forks vertically close to the trunk giving the Corkscrew Willow a shrub like appearance at early stages of development. Corkscrew Willow Trees are very adaptable to poorly drained soil and will withstand both full-sun exposure and partial shade.
