Akebia quinata, commonly known as chocolate vine, five-leaf akebia, or five-leaf chocolate vine, is a deciduous climbing vine native to East Asia, particularly China, Korea, and Japan. Like its relative Akebia trifoliata, it is widely cultivated in temperate regions worldwide as an ornamental plant for its attractive foliage, unique flowers, and edible fruits.
The leaves of Akebia quinata are compound and composed of five leaflets, arranged in a palmate pattern. The leaflets are typically oval to heart-shaped and have serrated edges. The foliage provides a lush backdrop for the vine's other features and turns shades of yellow and bronze in the fall before dropping.
The flowers of Akebia quinata are similar to those of Akebia trifoliata, appearing in pendulous clusters in early spring before the leaves emerge. They are purplish-brown to reddish-brown in color and have a sweet, spicy fragrance reminiscent of chocolate, hence the common name "chocolate vine." The flowers are attractive to pollinators like bees and butterflies.
After flowering, Akebia quinata produces elongated, sausage-shaped fruits that are initially green but turn purplish-black as they ripen. These fruits are edible, with a sweet, slightly tart flavor. They are sometimes used in culinary applications, such as jams, jellies, and desserts.
As a climbing vine, Akebia quinata requires support to grow, such as trellises, arbors, or fences. It is relatively easy to grow and can tolerate a variety of soil types and light conditions, although it prefers well-draining soil and partial shade to full sun. Hardy in zones 4-9.
