Single Snowdrops

We spent a lot of the day in the garden, pruning roses, and tidying up the beds to give more space to the Hellebores and snowdrops. I finally got around to sowing some sweet pea seeds. 
Then I discovered two pairs of frogs in amorous embraces  in our pond. Hopefully, there will be frogspawn soon.  
Here is one of the clumps of dainty, single snowdrops. The label has gone missing, so I'm not sure of the variety.
