Unidentified Plant

I would be most grateful to those of you who know more about plants than me, if you could help identify this plant. I have lots of these in the garden, it reminds me of Audrey, the plant in The Little Shop of Horrors! Hopefully it won't start eating us! I have noticed that eventually the green around the berries dies away just leaving the berries. The pods are about 3 inches long. Many Thanks for any suggestions.
