As Toffeeapple showed an interest [thanks!] here's a couple more of the flower. Yes - it dangles from a branch and is rather fantastic. Annoyingly I couldn't see a label to tell me what it was so it will have to remain the bauble flower to me. Answers on a postcard if anyone knows it?
Here's how they look furled up before springing out into the bauble effect. They remind me of raspberry ripple ice-cream.
