LEAVES: Simple leaves, 10 to 30 cm-long, strap-shaped, thickened and leathery. They have a shiny, resiny surface.

FRUIT: A long (15 cm), narrow, papery pod packed with cottony seeds.

RANGE: Widely distributed along streams, riparian areas, and washes with deep alluvium and underground water source.

Wildlife: Buff-colored cocoons about 25 mm in length are made by the inchworm moth, Eucaterva variaria. The adult moth is white speckled with black. Also, a spectacular hawk moth, Manduca rustica, is known to use this plant in the larval stage.

Hummingbirds and large black carpenter bees, Xylocopa californica arizonensis, rely on the Desert Willow's flowers for nectar. Colorful leafhoppers known as sharpshooters can be found drawing sap from developing pods and shoots.

UNARMED: No thorns.
