bush honeysuckle
bush honeysuckle, (genus Diervilla), genus of three species of low shrubs belonging to the honeysuckle family, native to eastern North America. Bush honeysuckles are frequently confused with members of the true honeysuckle genus (Lonicera), especially the related Tatarian honeysuckle (L. tatarica) and other cultivated species, which are invasive species in many parts of the United States. Diervilla species are attractive to butterflies and hummingbirds and are commonly used in native landscaping.

Physical description
Bush honeysuckles are deciduous perennials and have oval leaves and clusters of tubular flowers at the branch tips. They spread by rhizomes (underground stems) and form patches in rocky dry areas. Flowering occurs in early summer. The yellow or reddish yellow blooms are followed by slender beaked fruits.
Species
The northern bush honeysuckle (D. lonicera) and the mountain bush honeysuckle (D. rivularis) are similar except for the smaller size and more-pointed leaves of D. lonicera. The southern bush honeysuckle (D. sessilifolia) has stalkless leaves and angled branches.
