Propagation and sale of this plant are prohibited in Minnesota. Transportation is only allowed when in compliance with Minnesota Statute 18.82. Although Restricted Noxious Weeds are not required to be controlled or eradicated by law, landowners are strongly encouraged to manage these invasive plants on their properties in order to reduce spread into new areas.

Bell’s honeysuckle is a hybrid of two non-native species—Morrow’s honeysuckle (L. morrowii), which is native to Japan, and Tartarian honeysuckle (L. tatarica), which is native to Eurasia. It has become naturalized in many Northeast and Midwest U.S. states. It has spread from deliberate horticultural, wildlife habitat, and erosion control plantings, and is now fairly widely distributed throughout Minnesota.
Bell’s honeysuckle can invade a broad range of habitats, including open woods, fens, bogs, lakeshores, roadsides, pastures, old fields, and wood’s edges. It thrives in sunny sites and is relatively shade intolerant.
Bell’s honeysuckle reproduces asexually by root suckering and layering. The main method of spread to new sites is through seed dispersal by birds. Bell’s honeysuckle produces abundant seeds which are vectored by birds.

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.
