"Edelweiss" is a Rodgers and Hammerstein song from musical and film The Sound of Music, in which it was sung as a defiant statement of Austrian patriotism in the face of the Third Reich. It is named after the Edelweiss, a white flower found high on Alpine hills.
Edelweiss is a very winter-hardy grape variety derived from crossing the Minnesota 78 and Ontario grapes. It was developed by Elmer Swenson in 1980 in cooperation with the University of Minnesota.
