Pretty flower

Whilst staying with my friends in Alice Springs Annie made comment that I might want to get up a little early as she said that this plant outside the back door was going to flower in the night and the blooms will only last half a day if your lucky as the warmth of the day will destroy them. I did get up early and didn't get my arse into gear so when I got back early afternoon I expected them gone but it was a cool day so they where right out and just lovely. 1 hour later they were gone.
