Abutilon icanum, also known as hoary abutilon, pelotazo, pelotazo chico, and tronadora, is a shrub widespread throughout the arid, warm regions of the southwestern United States and northern Mexico.

It grows to between 0.5 to 2 meters in height; the leaves are ovate to lance-ovate in shape, with crenate margins, and sizes ranging from 0.5 to 3 cm in width and 1.5 to 6 cm in length. The solitary 5-petalled flowers are generally orange; in ssp. incanum they are 6-10 mm long and orange-yellow, while in ssp. pringlei they are just 4-6 mm and a deep orange with maroon spots. The 5-8mm-long fruits are capsules with 4-6 cells.

It favors rocky slopes and gravelly flats, and occurs in arroyos, at elevations up to 1,370 meters. Requiring warm-season rain and mild winters, it is found in the Sonoran Desert, but not the Mojave Desert.
