About Hibiscus coulteri Harv. ex A.Gray
Nomenclature and Taxonomy
Hibiscus coulteri, commonly called desert rosemallow, is a species of flowering plant in the mallow family, Malvaceae.
Native Distribution and Habitat Location
It is native to steep slopes and canyon walls in the eastern Sonoran Desert and the Chihuahuan Desert, which span the southwestern United States and northern Mexico.
Growth Form and Height
A short-lived perennial shrub, it grows to 6 ft (1.8 m) tall and is used in xeriscaping.
Drought Adaptation Traits
It is well-adapted to dry desert environments: its hairy leaves help conserve water, and its yellow flowers bloom primarily after rain events.

It is an important resource for pollinators during dry periods.
Landscaping Suitability
Despite being short-lived, it is recommended for dry-area landscaping, since it can grow with very little water.
