About plant names...
Coulter’s globe mallow is native to the Sonoran desert.
Identification: Plants reach 6-59" (15-150 cm) on sprawling
stems. Leaves are gray-green, soft, thin, with three or five rounded lobes with coarse teeth, ½-1¾" (1.5-4.5 cm) long.
Red-orange, white, or lavender flowers ⅜-¾" (9.5-19 mm) long have five roughly trapezoidal petals. It
blooms from March to April.
Coulter’s globe mallow flowers, along with other mallows in this family of 1500 species, have filaments that are united into a tube in the center of the flower. Another common example is the hibiscus.
