Small-leaf globemallow occurs in the Central Basin and Range and Colorado Plateau ecoregions (Lambert 2005). It occurs naturally in Nevada, the southern two-thirds of Utah, western Colorado, northwestern New Mexico, northern and central Arizona, and adjacent California (Kearney 1935; Holmgren et al. 2005; La Duke 2016; USDA NRCS 2017). It has been grown in southern Idaho (Pendery and Rumbaugh 1990) but is not native there. On the high plateaus of central and northern Arizona, small-leaf globemallow is the most abundant globemallow species (Kearney 1935). Although the distributions of small-leaf and Munro’s globemallow overlap in Nevada, Utah, and Colorado, it is common to find small-leaf globemallow in more southern and Munro’s globemallow in more northern locations (Sriladda et al. 2012).
