Desert Willow

Desert Willow is a perennial tree native to Edwards Plateau, South Texas Plains, Trans-Pecos, Rolling Plains. It grows best in full sun with low water needs.

Desert Willow (Chilopsis linearis) is a small native tree with showy pink, lavender, or white trumpet-shaped flowers that bloom from May through September. It is dog-safe (Desert Willow is not on the ASPCA Animal Poison Control Center toxic plant list for dogs, cats, or horses) and is the standard recommended swap for Oleander in Texas yards.

Despite the name, it is not a true willow; it is in the bignonia family alongside Crossvine. Hummingbirds visit the flowers heavily, especially Black-chinned and Ruby-throated species during migration. The seeds form long bean-like pods that birds eat in fall. Mature size is 15-30 feet tall and 10-20 feet wide.

Ecoregion notes for Texas. In the Trans-Pecos and South Texas Plains (alkaline rocky desert and brush country, less than 20 inches of rain): native and at home. Plant in full sun, water once a week the first summer, then leave it. In the Edwards Plateau and Hill Country (alkaline limestone): also native; it is one of the most reliable small flowering trees for that region. In the Blackland Prairie (DFW-Austin-San Antonio corridor, heavy clay): plant on a raised berm or amend the planting hole with decomposed granite to prevent root rot. In the Pineywoods: not recommended; too humid and too acidic.

Desert Willow is the swap to make if you have Oleander in a yard with pets. Mature size is similar (a substantial flowering shrub-tree), summer bloom season overlaps, and drought tolerance is comparable. Avoid heavy fertilizer; native woody plants bloom less when overfed. For HOA contexts, prune in late winter to maintain a single-trunk tree form rather than a multi-stem shrub if your community prefers a tidier look.
