Yes, well i'm happy to report that the whole 7 flowers lasted for the show, although 1 got slightly damaged on the way there in the car and fell off...
it was very hot during the show, so i kept mooving my parasol around to give it some shade, but even with some heat and sun, it seemed more or less ok during the day.
as i write, it is still in full bloom with 5 flowers still looking good. 1 flower is fading and i imagine 2 flowers will fade tomorrow or thursday, so all in all, i would say that it lasted in good condition for 2 weeks.
With some luck i will have seed in the autumn to share with anyone interested, and with the patience needed for them to reach flowering size!
I will upload some pictures from teh show at some point too
