Polly had some nice info - way to go.

As far as i know the edelweiss is actually the unofficial Swiss national flower, not Austrian, although any place you go in the Alps there is at least one group or another that has the Edelweiss as it's symbol.

Also, the primary Austrian dialect is similar to High German as the Southern American dialect is to Proper English, slower and in a thick accent, but still entirely the same as far as grammar and spelling go.
