Amur Honeysuckle

Lonicera maackii (loh-NIS-er-a MAK-ee-eye)

Family: Caprifoliaceae Non-native Vine (vertical)

This plant is problematic and alternatives should be considered. Please see the suggestions in the left-hand column. Amur honeysuckle is a deciduous shrub in the honeysuckle family (Caprifoliaceae) that is native to eastern Asia but has naturalized in much of eastern North America. It is a listed invasive in the central and eastern USA. The plant has been seen in the mountains, piedmont and coastal regions of North Carolina. The species epithet honors 19th-century Russian naturalist and geographer Richard Otto Maack. Amur honeysuckle is highly adaptable, forming dense stands that crowd and shade out native plants, greatly reducing biodiversity. It is shade-tolerant and resistant to heat, drought, and severe winter cold. Amur honeysuckle grows quickly to a tall shrub of about 15 feet. When cut, it grows back dense and vigorous from the stump. It leafs out early and retains its leaves longer in the fall and early winter, giving it a competitive advantage over native species. The fragrant flowers open white and age to a buff yellow. The fruits are enjoyed by birds, which spread its seeds. This species is not recommended for any garden or landscape, as it is aggressive and weedy. Insects, Diseases, and Other Plant Problems: No significant insect or disease problems. Listed as invasive by the NC Invasive Plant Council More information on Lonicera .
