Avonia flowers (the story)

I didn't expect it to be so tricky to catch these flowers. Now I know more and can be prepared for the next time. :) The first time I posted a picture of Avonia's flower buds 4.7 and it took them whole three weeks to arrive at this point. It would have been quicker, I guess, if the weather had played along but it was dark, cold, and rainy up untill two days ago. That's when the plant obviously decided to take advantage of the good weather window. Yesterday morning I've discovered that something has changed - there was a little white blob between the petals, and it grew bigger every hour (click the pic for larger version) until around 17:00 the flowers finally opened! Three or four hours later they have closed to never open again. It is a short-lived beauty. :)
