Desert Willow

Chilopsis linearis

Desert Willow is a drought tolerant, deciduous small tree prized for its trumpet-shaped flowers and appeal to hummingbirds.

Key Facts

  • Deciduous small tree or large shrub native to the southwestern United States and Mexico.
  • Showy tubular flowers in pink, lavender or white that attract hummingbirds.
  • Very drought tolerant once established and used widely in xeriscapes.
  • Prefers full sun for best flowering.
  • Tolerant of alkaline and poor soils when drainage is good.
  • Can be damaged by poor drainage and winter freeze in colder sites.
  • Easily propagated by seed and by cuttings.
  • Often multi-stemmed with narrow willow-like leaves.

Desert Willow (Chilopsis linearis) is a deciduous small tree or large shrub native to the southwestern United States and Mexico, prized for trumpet-shaped flowers that attract hummingbirds and for its drought tolerance in dry landscapes, but it can suffer from poor drainage and winter dieback in colder sites.

Identification

Often multi-stemmed with narrow willow-like leaves, Desert Willow produces showy tubular flowers in pink, lavender or white that bloom from late spring through summer. Mature plants commonly reach about 15 to 30 feet tall in favorable sites but frequently remain smaller where water is limited.

Best uses and where to grow

Plant Desert Willow in full sun for best flowering and use it in xeriscapes, dry slopes, or buffer beds where alkaline or poor, well drained soils occur. It is very drought tolerant once established, but avoid heavy or poorly drained soils that encourage root decline.

Planting time

Plant during the local frost-free planting window to allow roots to establish before cold weather. In milder climates aim for cooler months that permit root growth without extreme heat. Give newly planted trees supplemental water until they are established then reduce irrigation.

Planting spacing

Allow room for a broad crown. Desert Willow typically develops a 15 to 25 foot spread depending on form and pruning, so space specimens to match that mature spread when used as a specimen or street tree to avoid crowding.

Watering and soil

Desert Willow prefers well drained soils and tolerates sandy, rocky and alkaline conditions. It becomes very drought tolerant once established. Poor drainage or standing water can lead to root problems and decline, while regular irrigation during establishment speeds growth and flowering.

After-flowering care and pruning

Prune to control size and shape and to remove dead wood, preferably after the main flowering period. Plants that suffer winter dieback often resprout from the crown, so remove damaged branches in spring and thin crowded growth to maintain an open canopy.

Propagation

Desert Willow is propagated from seed and from semi-hardwood or hardwood cuttings. Seeds germinate readily and cuttings produce true-to-type plants for named selections. Timing and success vary by region and material so follow local propagation guidance for best results.

Frequently asked questions

How fast does Desert Willow grow?
Growth rate varies with climate and water. In warmer, irrigated sites it reaches mature size faster; in dry, low-water settings it often remains much smaller and grows more slowly.
Is Desert Willow hardy where I live?
Desert Willow is generally hardy in USDA zones 7 to 10 with possible winter dieback in colder areas. In colder sites expect crown dieback with resprouting from the base in spring.
Does it need full sun?
Yes. Full sun gives the best flowering. Light shade reduces bloom and overall vigor.
Is Desert Willow drought tolerant?
Yes. Once established it is very drought tolerant and is widely used in xeriscapes, though it requires regular water to establish quickly.
Is Desert Willow toxic to pets?
Data on toxicity is incomplete. Check local poison control or veterinary sources before assuming safety around children or pets.
