This is a version of the song Yuki no Hana (雪の华 in album LØVE, Mika Nakashima) sung by the voice actress Saori Hayami 早見 沙織.
The music was composed by Ryoki Matsumoto, and the lyrics were written by Satomi.
Thanks to animeyay ( http://animeyay.animelyrics.com/ ) for the liberally translated lyrics:
The english subtitles are edited versions, by me, of this lyrics to be 'in phase' with the song.
