About

Lonicera maackii, the Amur honeysuckle, is a species of honeysuckle in the family Caprifoliaceae that is native to temperate eastern Asia; specifically in northern and western China south to Yunnan, Mongolia, Primorsky Krai in southeastern Siberia, Korea, and, albeit rare there, central and northern Honshū, Japan.

Lonicera maackii is a listed endangered species in Japan. It has escaped from cultivation and naturalized in New Zealand and the eastern United States; in the woodlands of the U.S. it is a significant invasive species.

Safety

L. maackii produces various secondary metabolites to deter insect herbivory. Cipollini et al. found seasonal variation in the levels of chlorogenic acid, apigenin, apigenin-7-glucoside, luteolin and luteolin-7-glucoside, and confirm their deterrent effect.
