Native across the Central Great Plains, Chihuahuan Deserts, Cross Timbers, Edwards Plateau, Southern Texas Plains, and Southwestern Tablelands, Desert Willow (Chilopsis linearis) is an adaptable deciduous tree valued for both ornamental appeal and ecosystem support. It features distinctive green to olive green foliage.
During Spring, Summer, and Fall, the plant produces pink, purple, white blooms. After blooming, it produces green to greyish brown, 4-8 inches long.
It plays a key ecological role as a larval host plant for Central Texas butterflies, including Rustic Sphinx Moth and Dogface Butterfly.
Best suited to limestone, sand, and well drained, Desert Willow adapts seamlessly to local soil conditions. It requires minimal supplemental water and tolerates dry spells with ease. It offers moderate deer resistance.
