Akebia trifoliata / Mitsubaakebi ミツバアケビ

Akebia trifoliata is a deciduous climbing plant with gray-black-brown barks in fields and mountains. Leaves are alternate, of a ternate compound leaf with a 2-14cm-long petiole. Its leaflets are ovate, 2-6cm in length, 1.5-4cm in width, the tip somewhat cave in, and the bases round, with large undulate serrations on the margins. Flowers are monoecious; inflorescences droop down from leaf axils in which dark purple flowers come. The flowers lack petals, so sepals look like petals. The inflorescences set 10 or more male flowers on the tips and females, 1-3 in number, at the bases. Fruit (sap fruit), oblong, around 10cm long, ripen in purple to split open in September. Bloom time: April-May.
