Native to the SW USA, the Globe Willow is a drought-tolerant willow cultivar that gets its name from its distinctive globe, or umbrella, shape. These willows are cold hardy and tolerate a variety of soil and site conditions and can add a dramatic focal point to a home landscape year-round. These trees will thrive as perennials in U.S. Department of Agriculture plant hardiness zones 5 through 10. They grow 3 feet per year, with a lifespan of 40 to 150 years. The branches and bark are yellow when trees are young, maturing to a smooth olive-green. Some globe willow trees have been known to reach a trunk circumference of 150 inches. Leaves are light green in the spring, darkening to a medium green in the summer and have hints of yellow in the fall.
 
Note: while good for shade, the extensive root system of globe willows can clog plumbing and sewage lines if they are planted too close to buildings. As
