  1. Thanks for the info & particularly the good photos. I ate a berry thinking it was a black current then had my doubts. In seeing the photos above i instantly recognised the plant. Just to feed back: the taste was a little bitter but strange, as it didn't taste like anything i've had before. It certainly didn't taste like a sweet black current. the juice from the berry was green with little seeds in. i have to say, think back to it, i did have flatulence!! (while digging for my potatos before the moment) and dont have it now 1hr later???!!!.
