Akebia quinata, commonly known as chocolate vine, five-leaf chocolate vine,[1] or five-leaf akebia, is a shrub that is native to Japan, China and Korea, and invasive in the eastern United States from Georgia to Michigan to Massachusetts.[2][3][4] In its native habitat, it is often found on hills, in hedges, on trees, along forest edges and streams, and on mountainous slopes.[5]

Description[edit]

Akebia quinata is a climbing evergreen shrub that grows to 10 m (30 ft) or more in height and has palmately compound leaves with five elliptic or obovate leaflets that are notched at the tip.[6] The woody stems are greyish-brown with lenticels.[5] The flowers are clustered in racemes and are chocolate-scented, with three or four sepals. The fruits are sausage-shaped pods which contain edible pulp.[2][7] The gelatinous placentation contains seeds surrounded with white pulp, that has a sweet flavor.[citation needed]

Uses[edit]

The fruit contains a sweet soft pulp resembling a white dragonfruit, eaten primarily in Japan as a seasonal delicacy. The rind, with a slight bitter taste, is used as vegetable, e.g., stuffed with ground meat and deep-fried. The vines are traditionally used for basket-weaving.[8]

The stem contains approximately 30% potassium salts thus causing a diuretic action.[9][unreliable medical source?]

The fruit is used in Traditional Chinese Medicine to treat urinary tract infections, scanty lactation, and rheumatoid arthritis.

Cultivation[edit]

Akebia prefers sandy soils with good drainage, and regular watering, though it is drought-resistant.[10] In some areas the plant is an invasive species to be avoided.[11][12] This species in considered hardy in all of the UK and Europe (down to -15 to -20°C).[6] In the US, it suitable for hardiness zones 4–9.[13]

Etymology[edit]

Akebia comes from the Japanese vernacular name, 'akebi' (アケビ).[14]

Quinata means 'divided into five', and is presumably a reference to its lobed leaves.[14]
