Hairy Bush-honeysuckle

Hairy bush-honeysuckle (Diervilla rivularis), also called mountain bush honeysuckle, is a deciduous, suckering shrub native to the southeastern United States. It bears small pale-yellow to greenish-yellow flowers in summer, and its foliage can turn red, yellow, and orange in autumn. ## Size and siting Allow room for a spreading plant: the RHS gives a mature height of 1–1.5 m and spread of 1.5–2.5 m. Plant in full sun or partial shade in well-drained soil; the species adapts to chalk, clay, loam, or sand according to the RHS profile. ## Garden use Its suckering habit suits informal borders, banks, slopes, and screens where a colony can develop. Keep it distinct from invasive true honeysuckles in the genus Lonicera; the shared common name can cause confusion. Compare the [RHS species profile](https://www.rhs.org.uk/plants/5847/diervilla-rivularis/details), [Kew Plants of the World Online](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:80184-2), and [ITIS taxonomic record](https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=35311). ## Care Prune to manage size and remove damaged stems, keeping in mind that flowers form during summer growth. Monitor suckers and retain only the spread that fits the planting area. ## Maintenance
