The Aristolochia pistolochia

The hamlet of Pallon is in a sunny location. Around the village, a curious plant with long brown trumpet-like flowers grows on the edges of the stone piles in the fields and meadows: the aristolochia pistolochia or birthwort. Of Mediterranean affinity, this plant benefits from the hot dry climate here and is virtually at its northern boundary. It is the host plant of the caterpillars of a rare and protected butterfly: the Spanish festoon.
