Plant Profile: Three-Leaf Akebia (Akebia trifoliata)

Also called chocolate vine, this semi-evergreen to deciduous woody climber is native to rocky places in the woods and thickets of  Japan, Korea and China. and is a member of the Lardizabalaceae, a small family of about 40 species.  The branching stems rapidly grow up to 40′ long and trail on the ground or twine up nearby plants and structures.  The palmately compound leaves have three ovate, slightly lobed leaflets and are often bronze-tinted when young.  Short pendulant racemes of dark purple cup-shaped female  and smaller male flowers appear on the same plant in mid spring and are followed in the fall by light purple, sausage-shaped fruits  up to 3″ long that are edible and can be made into jelly.  Fruit production requires cross pollination.  The vigorous rapid growth of the plant makes it a good choice for a ground cover and for growing on fences and other structures, especially useful for creating a screen or hiding an undesirable object.  The genus name, Akebia, is the Latinized Japanese name for another species in the genus.  The specific epither, trifoliate, comes from the Greek prefix tri- meaning 3, and the Latin word folia meaning leaf, and refers to the 3 lobes of the leaves.
