Milk thistle.

Shot RAW (with a shadow tweak in Aperture) this morning while out on a walk along the trail.

Silybum marianum

Wikipedia data;

Milk thistles are thistles of the genus Silybum Adans., flowering plants of the daisy family (Asteraceae). They are native to the Mediterranean regions of Europe, North Africa and the Middle East. The name "milk thistle" derives from two features of the leaves: they are mottled with splashes of white and they contain a milky sap.
