I have this rather huge plant growing in a container ing the front garden.  All my containers had a mix of bulbs but I think this has snuck in from somewhere else.  I haven't a clue what it is!

Looks like a Nightshade but not Deadly Nightshade as that has reddish, bell shaped flowers.

Could be Black Nightshade - Solanum nigrum but difficult to say, there are hundreds

It`s definitely Solanum.

Well I definately didn't plant that!   I'll dig it up and see if I can coax some othe bulbs to sprout.

I had wondered if it was belladonna - pleased it's not, but still with chooks, cats and my friends young daughter visiting a lot, better to be safe than sorry.

This is Solanum nigrum.

Must give up work so I can try and answer questions on here!
