Diervilla, or bush honeysuckle, is a genus of three species of deciduous shrubs in the family Caprifoliaceae, all indigenous to eastern North America. The genus is named after a French surgeon Dr. Marin Diereville, who introduced the plant to Europe around 1700.

The bush honeysuckles are low in height, 1–2 m (3–7 ft), of small to medium diameter, 1–2 m (3–7 ft), and develop into colonies by means of spreading underground rhizomes. Their leaves are simple, opposite and either oval or lanceolate in shape with a toothed edge. The fall color varies between yellow, orange and red. Small tubular flowers, typically pale yellow, are produced in June and July.
