Antirrhinum Majus

Antirrhinum majus is a species of Antirrhinum native to the Mediterranean region, from Morocco and Portugal north to southern France, and east to Turkey and Syria. The common name derives from the flowers which, when squeezed, open their "mouths". The plants are pollinated by bumblebees, and the flowers close over the insects when they enter and deposit pollen on their bodies.
