Hello River
Are you having a good time out there in Tassie? It looks like it from the glimpses I've seen in your posts.
The flowers are edible so you can add them to salads as edible decorations and you can make tea out of the leaves. It has anti anxiety properties although I've not used it for that before. Perhaps someone else here has and can give us their views/experiences?
I just absolutely adore the smell and would happily grow the plant just to have that scent and the pretty flowers around.
