What is this?

Hi,

Any one have any idea what this plant is? Not sure whether to dig up or keep

Thanks

Looks like a type of Euphorbia possibly Ceratocarpa.

Looks like a caper spurge (euphorbia lathyris). Pull it out before if flowers or you'll have them popping up everywhere!
Use gloves. The sap can be irritant.

Thank you!
