Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Because of invasiveness problems, it is not recommended for planting. Emerging science reveals that Amur honeysuckle secretes chemical compounds that are harmful to amphibians, and fatally toxic to freshwater insects and crustaceans. Spring has officially arrived. Hand removal may be effective for very small plants or for light infestations. Oh, but some insect species do benefit from Amur honeysuckle. The species was first introduced to the U.S. in 1897, and for decades was promoted as an ornamental shrub. Where is this species invasive in the US.

It features tapered, ovate to lanceolate, medium to dark green leaves (to 3" long) and tubular, two-lipped, very fragrant summer white flowers (1" wide at throat) that age to yellow. Terrestrially, the chemicals of this plant also seem to inhibit native plant species — at least one study has found that canopy trees in heavily invaded plots had lower growth rates than trees found in non-invaded areas. The same goes for very late fall and early winter — this species is typically the last to drop its leaves. It tends to have an “arching” growth habit. Amur honeysuckle is a preferred egg-laying host for mosquitoes, and it generates high survival rates for mosquito hatchlings and larvae in aquatic environments. However, most edible honeysuckle plants are typically found in wildlife. This is an aggressive and invasive shrub that easily spreads by self-seeding. Invasive nature of this plant is a serious problem in many urban and rural areas of the U. S. Control measures include a range of options from digging out plants in sparsely infested areas to prescribed burning or application of chemicals such as glyphosate in heavily infested areas. Amur honeysuckle is a densely-branched, deciduous shrub that typically grows to 15' tall (sometimes more). Seeds are readily dispersed by birds.

Amur honeysuckle is a densely-branched, deciduous shrub that typically grows to 15' tall (sometimes more). Exotic honeysuckles leaf out early in the season and shade out native herbaceous ground cover. It is twiggy by nature and grows in what we refer to as a vase-shaped habit, the same general outline as an American elm but considerably smaller. Amur honeysuckle is a preferred egg-laying host for mosquitoes, and it generates high survival rates for mosquito hatchlings and larvae in aquatic environments. It was first introduced into the U.S. in 1855. Research shows that several bird species experience significantly greater nest predation when choosing Amur honeysuckle as their home. You can’t just cut them down and leave the stumps — they’ll grow back with a vengeance. It is distinguished from other honeysuckles by its short pedicils (nearly sessile flowers and berries).Genus name honors Adam Lonitzer (1528-1586), German botanist, the author of an herbal (Kreuterbuch) many times reprinted between 1557 and 1783.Specific epithet honors Russian naturalist Richard Maack (1825-1886). The species is shade tolerant, and resistant to heat, drought, and severe winter cold. It has been banned in Connecticut, prohibited in Massachusetts and designated as a Class B noxious weed in Vermont. is Central Ohio’s #1 “Least Wanted” non-native invasive species. Extremely aggressive and invasive, it may just be the most dominant of all plant species in the Central Ohio region. As if all this weren’t bad enough, our foreign occupier is also engaging in insidious chemical warfare. There’s a good chance that it’s Amur honeysuckle. Interestingly, though, it is not considered a “major player” in its native Manchuria (specifically, the Amur River basin running through Russia and China). The spring equinox occurred yesterday, March 20, at 12:15pm. This gives the species an energy advantage, and helps it shade out the (native) competition. Late summer, fall, or dormant season applications have all proven effective. Amur honeysuckle has also been found to increase mite and tick populations, and increase the incidence of illnesses like Lyme disease in humans. Birds spread its small red berries widely and across long distances. This plant is listed as a noxious weed in one or more Midwestern states outside Missouri and should not be moved or grown under conditions that would involve danger of dissemination. But, be sure to remove the entire plant to prevent resprouting. The species was first introduced to the U.S. in 1897, and for decades was promoted as an ornamental shrub. Lastly, the ruby-red berries of Amur honeysuckle are mildly poisonous to humans, and induce severe diarrhea when ingested. It can and does invade just about everywhere in the Midwest. Red berries appear in late summer, ripen in late fall, and often persist through the winter. Native A… Its berries are the natural equivalent of junk food — high in sugar, but very low in the fats and nutrients that migrating birds need to survive their long journeys. Amur honeysuckle has also been found to increase mite and tick populations, and increase the incidence of illnesses like Lyme disease in humans. It’s also considered to have cold properties, making it an excellent natural remedy for removing heat from the body as well as toxins. For many of us, honeysuckle may be one of the first foraged foods if only as drinking the nectar. The Garden wouldn't be the Garden without our Members, Donors and Volunteers.

The leaves are 2-3 inches in length, opposite along the stem, and end in a sharp point at the tip. This is because the honeysuckle produces sweet and edible nectar. See all that green around you in very early spring? Amur honeysuckle forms dense stands that crowd and shade out all competing species, greatly reducing native biodiversity. Nevertheless, some are medicinal and can be used in the treatment of asthma and different lung conditions. While its seeds attract birds and insects, its berries may be poisonous. For the next few weeks, most of the green we see around us will — counterintuitively — signify a suffering ecosystem. Unlike the natives it replaces, this shrub also supports very few caterpillar species — rendering it a very poor food source for birds (beyond its “junk food” berries). Flowers bloom in May-June. Flowers are white, aging to yellow, and bloom May through June. Mechanical: Fortunately, the root system is fairly shallow. Avoid herbicide applications during sap-flow (spring) as this lessens the effectiveness of the application. ) It features tapered, ovate to lanceolate, medium to dark green leaves (to 3" long) and tubular, two-lipped, very fragrant summer white flowers (1" wide at throat) that age to yellow. Herder Native Origin: Native to eastern Asia; introduced into North America in 1896 for use as ornamentals, for wildlife cover and for soil erosion control. Once spread into the wild, it can form dense, shrubby, understory colonies that eliminate native woody and herbaceous plants. Best in organically rich loams with good drainage. Amur honeysuckle (Lonicera maackii) is Central Ohio’s #1 “Least Wanted” non-native invasive species. It leafs out early and retains its leaves longer in the fall and early winter than native deciduous species. Attracts: Birds, Hummingbirds, Butterflies, Tolerate: Deer, Drought, Heavy Shade, Black Walnut. A 20% glyphosate solution (e.g., Roundup) can be sprayed or painted onto stumps at the time of cutting. Interestingly, though, it is not considered a “major player” in its native Manchuria (specifically, the Amur River basin running through Russia and China). Big mistake. It is a rapid grower, and when cut it just grows back stronger and denser from the stump. Will tolerate considerable shade. Within days, the foreign occupation of Central Ohio’s roadsides, streambanks, and forests will reveal itself. This shade-tolerant shrub has in the past been used for a variety of purposes including landscape ornamental, wildlife cover/food plant, hedge and erosion control shrub. This non-native honeysuckle is also a prolific fruiter. Lonicera maackii, commonly called Amur honeysuckle or bush honeysuckle, is native to Manchuria, Japan, Korea and China.
