Name that Plant - please!

It looks like a pink daisy so just might be a pink daisy - but is it?  However, it's on a stem which is about 75cm tall so not your average in-the-grass daisy.

​The other flowers, however, are very low level.  Maybe on stems which are about 20cm tall.  They are actually bluer than purple in real life.  


Any ideas would be gratefully received as then I can do some research!
