Hello! I live in the UK and my dad has these weird plants growing in his front garden but noone knows what they are...any ideas??
Ditto to Euphorbia lathyris. A nasty invasive weed, and with caustic sap too. Wear gloves when pulling it out, and watch out for all those seeds spreading around!
It's a weed?? really?? lol Thankyou very much, we just had no idea where it had come from or what it was lol thanks! :)
