Weeping willows are among the most commonly known trees around the world. These trees are used in landscapes, conservation efforts and ecology preservation and are found wild in nature. The reason weeping willows are so versatile and so well known is the broad range of geography for both natural and cultivated trees. Often the range of physical characteristics can cause problems for homeowners because of the rapid growth rate.
Originally from China, these trees spread to the Middle East and are found along the Tigris and Euphrates Rivers. Introduced into Australia, the willows became invasive and are now considered weeds that overtake other vegetation.
Weeping willows are found around the world except for the continents of Australia and Antarctica. Most willows are found in the Northern Hemisphere. Weeping willows can be found in North America as far north as Ontario, Canada. According to the University of Georgia, the original range of growth for the United States is along the Eastern states into the Southeastern area; the remaining areas are ranges that have been cultivated.
According to the Arbor Day Foundation, weeping willows can be found in U.S. hardiness zones 6,7 and 8. This extends the range of the tree across the country from Connecticut to Oregon, and south to Georgia.
Weeping willows are not found in the far northern Plains area north of Nebraska, or between Wisconsin to parts of Idaho. Southern Texas and Louisiana, as well as Florida, are not natural ranges for this tree. Other areas not noted for weeping willows include the New England states, California and the lower portion of Nevada.
The average heights of weeping willows reach 30 to 40 feet but can range to 60. The span of these trees can range up to 35 feet in diameter when fully grown. The root system of a weeping willow can extend far beyond the diameter of the tree itself. Roots of these trees seek out water because willow trees use large amounts.
