It is Euphorbia lathyris, common name Caper Spurge. These pop up quite readily, usually from bird dropped seeds, and they are quite prolifically reproductive. Classed as a weed, and where there's one this year, there'll be several next year. If you remove it, wear gloves - the sap from this plant is a skin irritant.
