 Desert Willow
Chilopsis linearis, Family Bigonia ( Bignoniaceae ), Desert Willow. Also called Sweet Desert Willow.  
Large deciduous shrub to small tree. Its long narrow leaves are willow-like. Its flowers are fragrant, pink to lavender. They appear in May and keep blooming until late September or frost. Native near the waterways in the Mojave Desert. It likes moderate water and sun. Does best in the desert. It is easy to grow for landscaping.  Though its many common names refer to it as a willow, it is not related to the willow species. Historically the desert willow has been used by the Pima to thatch roofs and for the enjoyment of the pleasant fragrance produced by the plant.

Plant desert willow tree in full sun or partial shade and in well-drained soil. For the first year, water deeply every five to seven days. Water established desert willow trees every two weeks in the summer and every month in the winter. Prune in spring just as leaves emerge to remove winter damage. To maintain a single trunk, prune the lowest limbs every spring until the tree is as tall as you want it. Most desert willow trees produce seedpods that may be safely removed anytime.
