A euphorbia of some sort?

Be careful with it as they can be rather toxic.

thank you, very imformative, its a euphorbia lathyns or caper spurge I will treat it with the utmost respect after reading everything about its poison attributes.

Well unless you're going to eat it (don't), all you should be aware of is that the milky white sap produced when you cut or damage this plant MAY irritate your skin, so wear gloves when handling it and don't get it in your eyes or mouth.
