Alpine Wildflowers

Nothing is as beautiful as hunting wild flowers on the Alpine mountain. Different from the forest flower that i saw, this time the color purple dominated the willow from dark purple to light purple. I also saw some flowers contract and cover their petals when night fell. Is this really happening or is there another reason? I have no clue either.
