Where is the japanese barberry native to

Cultivars that produce less seed pose a lower risk than high-seeding cultivars, though research suggests that the only completely safe cultivars of long-lived woody species are completely sterile cultivars.

Japanese barberry is a woody shrub with curving branches that have numerous sharp spines. The plant can grow six feet or taller. The leaves are small, rounded, and arranged in clusters above the spines.

Japanese barberry cultivars can range in color from chartreuse, gold, maroon, and green. Most naturalized Japanese barberry plants found to date have green leaves in the summer followed by vibrant orange and red fall foliage. Small yellow flowers bloom in May, followed by red oblong berries that persist into winter. Means of spread and distribution Japanese barberry seeds are spread by birds; plants also spread vegetatively by low branches that will root when they come in contact with soil.

Impact Japanese barberry infestations cause many detrimental ecological and economic impacts. Prevention and Management A two-step combination of mechanical and chemical treatments may be the most effective way to manage Japanese barberry.

Mechanical hand-pulling, cutting, mowing, or using brush saws methods can be used as an initial treatment, but to be most effective, they need to be followed by herbicide treatments. Foliar or cut-stump herbicide applications can be effective. Davis OH, Germination and early growth of Cornus florida, Sambucus canadensis, and Berberis thunbergii.

Birds spread the seed far and wide and branch fragments can readily root to form new shrubs, resulting in this invasive often forming dense thickets. It is also capable of becoming established in a variety of habitats, including areas with partial sunlight and deep shade.

Japanese barberry can be found in North America from North Carolina and Tennessee and north into Canada where it is found with a scattered distribution in southern Ontario, Quebec and Nova Scotia.
