Snowdrops

I had a go at photographing our snowdrops today using my mobile phone.
I tried using it in selfie mode but this didn't have a flash.
Then I tried shoving the phone underneath and just snapping.
This was about the best effort, difficult with them being so near the ground.
It is interesting that even though they are growing wild, they seem to have double and treble blooms. I wonder if this is natural?
