Chocolate Vine

Akebia quinata (Houtt.) Decne.
Lardizabala family (Lardizabalaceae)

Origin: Central China, Japan and Korea

Background
Also known as five-leaf akebia, this is an unusual and attractive exotic vine that was imported around 1845 for ornamental purposes.

Distribution and Habitat
It has been reported to be invasive throughout the mid-Atlantic to Kentucky with scattered occurrences elsewhere.

Ecological Threat
Akebia can form an impenetrable groundcover and when climbing shrubs and trees forms a dense tangle that creates deep shade for the vegetation it covers.

Description and Biology

Prevention and Control
Young plants can be pulled by hand. Cutting can be done any time of year and vines should be cut to the ground. Vines may be dug up, removing as much of the roots as possible. For large infestations, a systemic herbicide containing glyphosate or triclopyr is effective (see Control Options).

Native Alternatives
Pipevine (Aristolochia macrophylla), cross-vine (Bignonia capreolata), trumpet creeper (Campsis radicans) and trumpet honeysuckle (Lonicera sempervirens).
