Edelweiss is a well-known Europe mountain flower.

Description

Leaves and flowers are covered with white hairs and look woolly. Each Edelweiss bloom has five to six small yellow flower heads surrounded by leaflets in a star shape. The flowers are in bloom between July and September. The flower also is known as national flowers of Austria and Switzerland.

Range

The Edelweiss prefers rocky limestone places. It has been used traditionally in folk medicine. The hair on the flower protect the Edelweiss from cold.
