I have quite a few Akebia in my garden. There are a few Akebia quinata in the front and back yard. They have nice purple seperate male and female flowers. Akebia quinata 'rosea' has paler purple to rose colour flowers. Akebia quinata 'Shinobana' has white flowers. Akebia trifoliata has deep deep purple flowers that are almost black. They are native to Japan and China, and here in Vancouver, they are evergreen and keep their foliage thru winter.
