Size and method of climbing:
Five-leaved akebia can grow 25 to 30 feet long. It is a twining vine. Twining vines climb by twisting their stems or leaf stalks around a support. This type of vine grows well on trellises, arbors, wires, or chain-link fences.
Native geographic location and habitat:
It is native to China and Japan.
The alternate leaves are palmately compound with five leaflets each. Each leaflet is oblong with an entire margin. Newly emerging leaves are tinged with purple, then change to green in summer. Leaves stay green in fall.
Male and female flowers are borne on the same plant. Each flower is small, but they are held in clusters of two to five. The dark purple flowers are fragrant.
Akebia has a fleshy pod-like fruit (a follicle). The oblong fruit is 2 to 4 inches long, purple on the outside and white inside. Fruit is not always produced. It is thought that flowers on one plant may need to be pollinated by flowers from another plant.
This vine is very shade tolerant and grows well in part sun to full shade. It is tolerant of drought and poor soils.
