weird plant??

Hi, My name is Leon Christensen. I live in Denmark and my question is this.

For about 6 years i have had a plant in my garden. It never produced any kind of flowers or anything else besides leaves..
Suddenly it has begun to produce these purple cocoon like things .. inside there a cotton substence with black seeds.
They are about 10cm long.

What is this plant???

Wow, that looks really familiar - hopefully someone can put a name to it.

My guess is Akebia, and in that case those pods may be edible....

Thanks you so much )
Was driving me crazy!!
Is it eatible?? ( not spelled correct)

So regart to eateble comment) my bad)

It looks awful similar to this picture of the caper fruit and seeds. The bud is normally pickled as the caper, but the caper berry shown is also eaten in Greek cuisine, IF it is that plant. Looks cool, hope it is something useful.



Edit:
I keep changing my mind.. there are a lot of differences besides the similar overall appearance.

It looks like akebia quinata to me, because of the leaves. I have tasted mine, and didn't much care for it, but the flowers are great. I really do like the flowers, and nothing seems to bother it, It is not fussy about conditions either, at least not here in Oregon. That would be my guess.

Here is a link for akebia quinata..

I hope this helps. A common name is chocolate vine.
