About Desert Willow (Chilopsis linearis) It is a small tree native to the southwestern United States and Mexico. Despite the common name Desert-willow, given because of its willow-like leaves, it is actually a member of the bignonia family, Bignoniaceae. It is commonly seen in washes and along riverbanks at elevations below 1500 meters in the Colorado and Mojave Deserts. Ranging from 1.5 to as much as 8 meters in height, it can have the general appearance of either a shrub or a small tree. The linear curved leaves, ranging from 10-26 centimeter in length and 2-4 millimeter broad, are deciduous. It has fragrant pink flowers that hummingbirds love.

Because it is winter deciduous, it will be leafless half of the year. However, in Spring and Summer its flowers justify inclusion in a sunny, inland garden.
