The "Edelweiß" is an alpine plant which is very rare and it is strictly forbidden to pick it up.
Since it is so typical for the Alps, it is also a symbol for the Alpine culture.
Unfortunately this symbol is often abused to give commercial things a traditional touch.
Therefore the word "Edelweiß" is sometimes an indicator for commercialized tradition, for example in songs, dance names, names of hotels etc.
If you are looking into my index, you'll find an example for an exception to this rule: The Austrian folk dancing group "Edelweiß" which is part of the Austrian "Alpenverein".
