Bee's tea

I was watering the garden this evening and I spotted a couple of buds beginning to open on this Passion Flower. In the 20 minutes or so it took to complete the watering I noticed they'd opened - and it looks like I wasn't the only one to notice the change!
I also noticed I have a couple of little green fruits - it's the first time this has happened - but I understand sadly  they're not edible.
