Sagebrush false dandelion is distributed from south-central British Columbia to northern California, northern Nevada and Utah, largely east of the Cascade and Sierra Nevada mountains, and eastward across western and central Montana and northwestern Wyoming (CPNWH 2017; SEINet 2017; USGS 2017).PDF UPDATED: FEBRUARY 2024.

Royal penstemon occurs from the eastern slopes of the Cascade and Sierra Nevada Mountains eastward across central and southeastern Washington, eastern Oregon, and southwestern Idaho, and south through eastern California and Nevada to higher elevations in mountain ranges on the northern edge of the Mojave Desert (USDA NRCS 2017). A few populations are found in Utah.PDF UPDATED: APRIL 2024.

Gooseberryleaf globemallow is native to North America and occurs primarily in the Intermountain region in the western states of Washington, Oregon, Idaho, Nevada, Utah, Arizona, and New Mexico (La Duke 2016). It is also reported in northern California but may reach its maximum abundance in Utah (Kearney 1935). Plants are winter hardy, especially in regions with at least periodic snow cover. They are most abundant on open or disturbed sites receiving 8 to 12 inches (200-300 mm) of annual precipitation (Wasser 1982; Stevens et al. 1985).PDF UPDATED: MAY 2024.

Munro’s globemallow is a western species occurring in southern British Columbia, east of the Cascades in Washington and Oregon, as far south as Nevada and Utah and as far east as southwestern Wyoming (Welsh et al. 1987; Holmgren et al. 2005; La Duke 2016; LBJWC 2018). Munro’s globemallow is more common in northern Utah and the Wasatch Plateau, whereas gooseberryleaf globemallow is more common in the southern part of the state (Pendery and Rumbaugh 1986).

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...

Aspen fleabane is widely distributed throughout western North America. In Canada, it occurs in British Columbia and Alberta. In the United States it occurs in western South Dakota and all states to its west, except California. However, there is a population in Baja California that is disjunct from the nearest southernmost populations in Arizona (Nesom 2006). Aspen fleabane is particularly common in the Great Basin and Intermountain regions (Hermann 1966).

Showy goldeneye is a western species. Variety multiflora is the most widely distributed, occurring in Montana, Idaho, Wyoming, Colorado, Utah, Nevada, Arizona, New Mexico, and Texas. Variety nevadensis is more southerly, occurring in California, Nevada, Utah, Arizona, New Mexico, and as far south as Jalisco, Mexico. Variety brevifolia occurs in Utah, Arizona, and New Mexico (Schilling 2006). Variety multiflora is found at higher elevations or in moister habitats than variety nevadensis where their distributions overlap (Cronquist 1994). In Montana, variety multiflora is primarily found in...

Arrowleaf balsamroot is primarily a western species occurring from the Cascade and Sierra Nevada mountain ranges to the Black Hills of South Dakota. It is found in the Canadian provinces of Alberta, British Columbia, and Saskatchewan and in the U.S. states of Arizona, California, Colorado, Idaho, Montana, Nevada, Oregon, South Dakota, Utah, and Wyoming (USDA FS 1937; Weber 2006). It is particularly widespread east of the Cascades at low to mid-elevations (Hitchcock and Cronquist 1973).PDF UPDATED: FEBRUARY 2024.

Douglas’ dustymaiden is native to North America and is widely distributed throughout the West, occurring from southern Alberta, British Columbia, and Saskatchewan to California, Nevada, northern Arizona, northern New Mexico, Colorado, and the Dakotas (Cronquist 1994; Morefield 2006; LBJWC 2017). Variety douglasii is more widespread, occurring throughout the range reported for the species. Variety alpina occurs only in Montana, Idaho, Oregon, California, Utah, Colorado, and Wyoming (Morefield 2006).PDF UPDATED: FEBRUARY 2024.

Tapertip hawksbeard occurs in all states west of Montana, Wyoming, Colorado, and New Mexico (Bogler 2006). It is common in and east of the Cascade and Sierra mountain ranges and found in the northern parts of Arizona and New Mexico (Cronquist et al. 1994; LBJWC 2018). Populations are most common in the Columbia Plateau and Great Basin provinces (Babcock and Stebbins 1938) and exist in most, if not all, counties in Utah (Welsh et al. 1987). In general, tapertip hawksbeard occurs in regions with continental climates that experience dryness in all seasons (Babcock and Stebbins 1938).
