Sound of Music - The Edelweiss is the unofficial national flower of Switzerland and popular in Austria. In the Republic of Austria, it appeared on the 1 Schilling coin and can now be seen on the 2 cent Euro coin. The edelweiss is also worn as a cap device by certain Austrian Army mountain units. The musical itself is virtually unknown in Austria, except in backpacker's hostels in Salzburg, where the film is screened daily on DVD.
