Finally- Akebia fruit!
I have 2 Akebias, quinata and trifoliata, that have been growing on an arbor for about 5 years. Though they have flowered several years, this is the first year I have got any fruit, and only on quinata. Perhaps I should have been hand-pollinating all along. I will try that next year.
Akebia are a lovely vine and evergreen where I am in zone 8. Only the pulp is edible, a sweet gelatinous confection full of seeds. The pods split open by themselves and are a pale blue-lavender, and look like something from outer space.
Paghat has an interesting webpage on them.
