Facts
Chocolate-vine is a twining vine from Korea and Japan. It has distinctive, five-"fingered" compound leaves with notched tips. Its brown flowers give it its "chocolate" name. This fast-growing vine can become invasive. Its sausage-shaped fruits are edible, though apparently taste bad.
Habitat
Anthropogenic (man-made or disturbed habitats), forest edges, forests, meadows and fields, ridges or ledges
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

1. Akebia quinata (Houtt.) Dcne. E
chocolate-vine. CT, MA; also reported from RI by George (1992), but specimens are unknown. Roadsides, forest fragments, open ledges, waste areas, fields.
1×Akebia trifoliata Koidz. Akebia ×pentaphylla (Makino) Makino is a rare chocolate-vine hybrid known from MA. It is similar to A. quinata but shows leaves with 3–5 leaflets that have prominent crenations along the margins. Akebia quinata, on the other hand, has leaves with (3–) 5 (–7) leaflets that have entire to undulate margins (rarely with 1 or 2 obscure teeth).
