On this arid soil, you can see a discreet broom (shrub) against the ground: Villars broom (Genista pulchella subsp. villarsii). Its meagre look is an adjustment to sunny and dry environments: It sweats very little! Sharing space with some species which are also frugal, the Villars broom is the structuring element of a natural environment, rare and protected by Europe: from "heath to Villars broom".
