Forget-me-nots

Believe it or not, this is my neighbour's back garden. Years ago it was 'paved and pebbled' over to make it 'low maintenance' for the elderly man who lived there. The current neighbours seem to think 'low maintenance' means 'no maintenance' as they just do nothing whatsoever to it. Consequently, these forget-me-nots are doing their best to take over the entire garden and making it look pretty for a while at least!
