About Diervilla rivularis Gatt.
Diervilla rivularis Gatt. is a species of flowering plant in the honeysuckle family, commonly known as mountain bush-honeysuckle and hairy bush-honeysuckle. It is native to the eastern United States, where its distribution is restricted to the southern Appalachian Mountains. It can be found in Alabama, Georgia, and Tennessee, and it is extirpated from North Carolina. This species is a compact perennial shrub that reaches 0.91 to 1.83 meters (3 to 6 feet) in height. Its flowers are trumpet-shaped, two-lipped, and range in color from pale yellow to greenish yellow. Its leaves are simple, hairy, arranged oppositely, and oval or elliptical in shape. This plant grows in moist wooded areas and disturbed sites such as roadsides, and it occurs at middle to higher elevations across its native range. The Latin specific epithet rivularis translates to "loving brooks", a reference to the species' preference for growing in moist habitats. Diervilla rivularis is considered somewhat threatened by habitat loss caused by land-use conversion, habitat fragmentation, and forest management practices.
