Dianthus sp.

This flower was seen at the Reader Rock Garden on 24 June 2015. I've just been searching Google, but have had no luck in finding an ID for this plant. Any help would be much appreciated - thanks!

After two days of fog, we finally have sunshine this afternoon, 13 February 2016. Temperature is +7C and it looks a lovely day to be out. However, I have so many things to see to at home, so I mustn't go off for a drive anywhere.

ID: Dianthus species.
