Family

Bignoniaceae

Botanical Name

CHILOPSIS linearis

Plant Common Name

Desert Willow

General Description

An upright, multi-stemmed, deciduous shrub or tree native to the deserts of Mexico and the southwestern United States, this willowy-leaved plant bears large, fragrant, tubular flowers from late spring until fall. The white, pink, or lavender flowers have yellow, purple-veined throats. Long bean-like pods follow the flowers. The long, green, narrow leaves drop in early fall. Many cultivars have been selected for flower color, habit, and other characteristics.

Desert willow is adapted to coarse, dry alkaline to acidic soils and full sun. It is a colorful garden plant that may also be used in land reclamation plantings. The flowers attract hummingbirds and butterflies. Plants growing in drier soil conditions produce lighter flower color pigments compared to the same plants grown in slightly moister conditions.
