Solidago missouriensis is a species of flowering plant in the aster family known by the common names Missouri goldenrod and prairie goldenrod. It is native to North America, where it is widespread in Canada and the United States.[1] Its distribution extends into Coahuila in Mexico.[2]
This plant is variable in appearance, and there are a number of varieties.[2] In general, it is a perennial herb growing from a caudex or rhizome, or both. It reaches one meter in maximum height. The roots may reach 2 m (6.6 ft) deep in the soil.[1] The rigid leaves are up to 30 centimeters (12 inches) long, becoming smaller farther up the stem.[3] The inflorescence is a branching panicle of many flower heads at the top of the stem. The head contains about 8 yellow ray florets a few millimeters long and several disc florets. The fruit is an achene tipped with a pappus of bristles.[1]
This plant can be found in many types of habitat. It is common on the Great Plains. It grows preferably in dry, open habitat and can occur at high elevations. It colonizes disturbed soils. During the Dust Bowl-era drought, when many of the native grasses and plants died, the goldenrod flourished in the dry, cleared soil. As the drought ended and the grasses returned, the goldenrod became less common, disappearing in many areas. It grows in soils turned over by burrowing animals and on roadsides and mining sites.[1]
The goldenrod is common in a number of regions, including tallgrass prairie in west-central Missouri, sandhills prairie in southeastern North Dakota, the Cypress Hills of southeastern Alberta, riparian habitat in northwestern Montana, and the pine barrens of northern Wisconsin.[1]
