Sphaeralcea ambigua, commonly known as desert globemallow or apricot mallow, is a member of the genus Sphaeralcea in the mallow family (Malvaceae).

It is a perennial shrub native to parts of California, Nevada, Utah, Arizona, and New Mexico in the United States and Sonora and Baja California in northwest Mexico. It grows well in alkaline soil, both sandy or clay, usually in the company of creosote bush scrub and desert chaparral habitats, at 150–2,500 metres (490–8,200 ft) in elevation. It is found in the Mojave Desert, Great Basin desert, and Sonoran Desert ecoregions. It is a larval host to the common checkered skipper, northern white skipper, painted lady, small checkered skipper, and West Coast lady.

Description

The Sphaeralcea ambigua plant grows to 3 feet (0.91 m) in height and spreads to 2–3 feet (0.61–0.91 m) in width. The leaves (see image) are fuzzy with white hairs on both sides, lobed, palmately veined, and on long stems, the number of which increase with age. The fruit is a brown capsule containing numerous seeds, first quite spherical as implied by the genus name, later flattening to a disk. The flowers are bowl-shaped, five-petaled, apricot to orange in color, and blooming in the spring.
