A Lone Snowdrop

When I moved into my current house I had a new lawn laid outside the back door. Because it's under a large tree it doesn't do too well and has gradually changed to lots a daisies and weeds. The current weather hasn't helped.

In the last few days a single snowdrop has appeared on the edge of the lawn. I haven't a clue where it came from but it does brighten up the back garden.
