Solanum opacum

Has anyone grown Solanum opacum? I have seen it referred to by the common names ‘morelle verte’ or ‘green berry nightshade’.

I have read some amazing things about its taste, but they feel like exaggerations and hype to me. I am wondering if it is worth buying seeds and giving it a go? They are very expensive and only one place here seems to carry them.

Did you end up buying this variety? How did it taste?
