Hertfordshire,
United Kingdom 
Hi there! Does anyone know what this plant is? I asked at my local garden centre and they had no idea! It appeared last year, died down over winter, and has reappeared this year. It’s huge, over 4ft tall, has green flowers and has just sprouted pod like things under the flower heads. I’d be very grateful for identification, I’m really curious to know what it is. Thanks.

Must be Beattie!

I've been googling and think that it's Euphorbia lathyris.

That's it, Beattie. We grow it as a gopher-repelling companion plant in veggie gardens, but it can turn into a weed!

It's also a good mole deterrent, but I don't want 5 acres of the blooming stuff.

Thanks all! So, I have a highly toxic weed!!! It's unusual and I like it though, so will be keeping it and making sure I don't do anything to provoke a sap attack! So pleased to know what it is, it's definitely a euphorbia lathyris Beattie. Thanks again for letting me know, very much appreciated.

It's a wild kind of Euphorbia - either a wild flower or a weed, depending on your point of view - yours is the third that's been asked about in recent weeks. At least I think it was euphorbia...
