Not sure!

My neighbour told me I could photograph all the lovely flowers in her garden while they're away (she's a very good gardener!) and was completely spoiled for choice when I ventured up there just now - peonies, geraniums, roses - you name it.  Then I spotted a smallish tree covered with these little white bell-like flowers so I've chosen it as my blip.  I've no idea what they are so if anyone does I'd love to know!

And thanks as always to BikerBear for hosting the lovely FF challenge.
