The prairies which surround the Tardieu hut are called “tall-festuca grassland”. This name comes from the dominant plant species, a tall kind of grass which grow in tall, tough clumps. The list of plants which grow alongside this tall grass and form the combination of plants constituting tall-festuca areas is long, but one of the jewels in the crown is surely Alpine sea holly or Queen of the Alps with metallic blue shades. This is currently the last area with Alpine sea holly in Ubaye, the department and the National Park.
