Noteworthy Characteristics

Chilopsis linearis, commonly known as desert willow, is a large shrub or small multi-trunked tree with a loose open crown. It typically grows to 15-25’ tall with a spread to 10-15’ wide. It is native to gravelly and rocky soils in the Southwestern U.S. and northern Mexico where it is usually found growing in desert grasslands, sandy washes or springs. This is a monotypic genus having only one species with two varieties thereunder, namely, var. linearis and var. arcuata.

Showy, fragrant flowers bloom from April to September with fruits maturing in fall and often remaining on the tree during winter. It is treasured for its delicate, deciduous, willow-like leaves and trumpet-shaped, catalpa-like flowers (each to 1 1/2” long) which bloom in 2-4” terminal panicles from May to September. Flowers are lavender to pink but occasionally white. Light green leaves (to 6-12” long spreading to only 1/2” wide) are alternate, simple and linear to narrow lanceolate. Flowers are followed by distinctive, slender, 1/4” wide seed pods (to 6-12” long), each pod containing many winged seeds.

Var. linearis is native to far southern Utah, Arizona, New Mexico, western Texas and northern Mexico. Its branchlets are non-viscous and usually lanate.

Genus name Chilopsis comes from the Greek words cheilos meaning "lip" and opsis meaning "resembling" in reference to the distinct lip found on its calyx.

Specific epithet means narrow with nearly parallel sides in reference to its willow-like leaves.
