It is a compact, perennial shrub that grows 3–6 feet (0.91–1.83 m) tall.[2] Flowers are trumpet-shaped, two-lipped, and pale yellow to greenish yellow. Leaves are simple, hairy and opposite, oval or elliptical.[2] This plant grows in moist wooded areas and disturbed areas such as roadsides.[3] It occurs at middle to higher elevations in its range.[1] The Latin specific epithet rivularis means loving brooks. It refers to the plant's preference of growing in moist habitats.[2]

The plant is considered "somewhat threatened" by habitat loss due to land-use conversion, habitat fragmentation, and forest management practices.[1][4]
