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.[1][2] 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.[2] It is a larval host to the common checkered skipper, northern white skipper, painted lady, small checkered skipper, and West Coast lady.[3]

Description

Sphaeralcea ambigua grows to 3 feet (0.91 m) in height and spreads to 2–3 feet (0.61–0.91 m) in width.[4] 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.[2]

Varieties

Sphaeralcea ambigua has eight or nine named varieties.[5] They include:

  • Sphaeralcea ambigua A. Gray var. ambigua [6]
  • Sphaeralcea ambigua A. Gray var. aculeata Jeps. (synonym for S. a. var. ambigua) [7]
  • Sphaeralcea ambigua A. Gray var. rosacea (Munz & I.M. Johnst.) Kearney [8]
  • Sphaeralcea ambigua A. Gray var. rugosa (Kearney) Kearney [9]

Cultivation

Sphaeralcea ambigua is cultivated as an ornamental plant by specialty plant nurseries for use in desert and drought tolerant gardens, and a native plant its desert region's natural landscaping and habitat restoration projects.[4] It requires the following conditions:[4]

  • Exposure: full sun
  • Water: natural rainfall; supplemental water will increase flowering
  • Soil: desert soil, tolerant of some clay, prefers good drainage
  • Propagation: easy by seed; tricky by vegetative cuttings; best results from first flush of new spring growth
  • Maintenance: low, periodically cut back to keep vegetative look

It is winter hardy in USDA Zones 6-10, withstanding temperatures as low as -10F.[11]
