this started growing in a bucket that I used for discarded bulbs after sifting my garden last autumn ... But for the life of me I have no idea what it is! It just burst to life and its sooooo intersting I've put it next to my fish pond !!! Any help is greatly appreciated!

Euphorbia lathyris, we had another recently on here.

The thread "Unknown plant" in Plant ID forum

Thanks so much. I still have no idea how it got in my garden in the Midlands!!!

It was probably brought by a bird or maybe a neighbour had it. I haven't had one for some years now, they are interesting!

Mine appeared from nowhere too. I've had some other surprises appear from nowhere, I had Burdock (Arctium minus) in 2014 but not since.

A single plant of Lemon Catmint (Nepeta cataria citriodora) grew in a pot in 2011, it eventually died but I have a lovely lush plant growing since last year where the Burdock was.
