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.
Tatarian honeysuckle is native to eastern Asia. It was introduced to the U.S. in the 1700s as an ornamental. It has since spread and naturalized in the Eastern and Midwest United States. It is established in most of the counties in Minnesota.
Tatarian honeysuckle invades and thrives in woodlands, roadsides, mature and disturbed forests, savannas, fence rows, meadows, old fields, and pastures. It can grow in full sun to shade, and moist to dry, gravelly, or sandy soils.
Tatarian honeysuckle reproduces asexually by root suckering and layering. The main method of spread to new sites is through seed dispersal by birds. Tatarian honeysuckle produces abundant seeds which are vectored by birds and mammals.
It is documented in most of the counties of Minnesota, and is fairly widely distributed. View Tatarian honeysuckle distribution in Minnesota.
High densities of honeysuckles can suppress native plant and timber regeneration and form monocultures. Ecosystem richness and density of tree seedlings are substantially reduced in honeysuckle infestations. This species can alter a habitat’s microclimate, by creating dense shade, depleting soil moisture and nutrients, and possibly releasing allelopathic chemicals that inhibit growth of other plants. It can be especially harmful to spring ephemerals, due to its early leafing.
