Japanese Honeysuckle

Flowering period


Japanese honeysuckle is a perennial, trailing or climbing woody vine with opposite, simple, pubescent leaves. The leaf shape varies from ovate and entire in mature leaves to lobed in young leaves. The fragrant white to yellow flowers are born in pairs on axillary peduncles. The fused corolla is 1.2-1.8 inches long, with a pubescent tube. The inconspicuous berries are small, black and sessile. It is distinguished from native twining honeysuckles by the fact that members of each pair of its leaves are distinct, whereas at least some of the opposite leaves of native twining species are united.

DuPage County Notes

This introduced Asian species is a serious pest plant south and east of our region. Fortunately it rarely flowers this far north. It can grow in wooded or open areas.
