Efforts must be made to prevent seed maturation and dispersal of plants into new areas. Additionally, no illegal transportation, propagation, or sale of these plants is allowed. Failure to comply may result in enforcement action by the county or local municipality. Minnesota Noxious Weed Law.
Amur honeysuckle is native to Asia. It was planted as an ornamental in New York in the late 1800s and has been widely planted for wildlife and erosion control. It has naturalized in the east and Midwest United States. The amount of Amur honeysuckle in Minnesota is likely very small, but it has not been well studied.
Amur honeysuckle is able to grow in a range of conditions from sun to deep shade and wet to dry soils. It thrives in disturbed sites, including forest edges, woodlots, floodplains, old pastures, fields and roadsides.
Like other honeysuckles, the fruits are abundant and highly attractive to birds, which spread seeds to new areas. Vegetative sprouting from adventitious roots also aids in local spread.
Amur honeysuckle has invaded and naturalized in most mid-Atlantic and Midwestern states. It is established in Wisconsin and a handful of individuals have anecdotally been reported in Minnesota. View Amur Honeysuckle distribution in Minnesota.
Amur honeysuckle can rapidly invade and overtake a site, shading and crowding out native species. It can alter habitats by depleting soil moisture and nutrients, possibly releasing toxic chemicals that prevent other species from growing in the vicinity, and suppressing regeneration of native tree seedlings. The growth of overstory trees can be significantly reduced by dense Amur honeysuckle in the understory. Reduced timber production may be costly. Dense infestations can locally increase the populations of ticks and the risk of tick-borne diseases.
Berries may be mildly poisonous if eaten by humans.
