Japanese honeysuckle is native to eastern asia: parts of China, Japan, and Korea. It has become naturalized in much of the rest of the world, including North America; in some habitats it is considered an invasive species.
Here are some honeysuckles:
|You are here
|Plant||Shrubs are 3-9½' (1-3 m) around||A vine up to 16' (5 m) in size. Young stems are reddish- or light-brown, while older stems are hollow, with peeling bark||Trumpet honeysuckle is a twining vine 3-20' (91-609 cm) long, depending upon what it has to climb over. Bark is orange-brown, and peeling.|
|Flowers||Blooms are a creamy white color, in pairs, appearing in March-April, and very fragrant, with a lemony smell||Flowers are white, showy, fragrant, about 1" (2.5 cm) in size. They fade to a yellow color, so the vine appears to have white and yellow flowers||In clusters of 2-4, each red or orange with yellow interiors, 1-2" (2.5-5 cm) long, trumpet-shaped. They appear from April to July.|
|Leaves||Leaves are opposite, roughly oval, with smooth edges||Leaves are opposite, roughly oval-shaped, with smooth edges. Younger leaves may have lobes||Roughly oval in shape, opposite, bluish green, and 1-3" (2.5-7.6 cm) long. Leaves at the base of flowers are fused at the base.|
|Fruit||Orange to red berries up to ⅜" (1 cm) across||Black, about ⅛" (3.2 mm) around||Berries are orange-red to deep red in color|

Identification: Japanese honeysuckle is very robust—a rapidly spreading vine that spreads by roots, aboveground runners, or seeds. They can reach 16' (5 m) in size. Young stems are reddish- or light-brown, while older stems are hollow, with peeling bark. Leaves are opposite, roughly oval-shaped, with smooth edges. Younger leaves may have lobes. Flowers are white, showy, fragrant, about 1" (2.5 cm) in size. They fade to a yellow color. Most of the time it looks like there are two differently colored flowers on the bush. Japanese honeysuckle berries are black, about ⅛" (3.2 mm) around. Native honeysuckle berries are red to orange.
Edibility: Flowers can be used for nectar, and leaves parboiled for use as a vegetable. Leaves contain somewhat toxic saponins, so boiling in ample water is necessary to remove them. Tea can also be made from leaves, buds, and flowers.
