This was released as the first official single to be lifted from Kylie Minogue's The Abbey Road Sessions album. The LP was made to celebrate Minogue's 25-year music career and mainly features reworkings of some of the singer's classic tracks. "Flower" premiered on radio on September 24, 2012 and was made available to download the following day.
Minogue originally wrote the song in 2007 as she was undergoing treatment for breast cancer. She explained that her lyrics are addressed to a possible future baby. Said Kylie: "It's a love letter to the child I may or may not ever have. I was coming out of (cancer) treatment. You're told 'We can't determine what your future's going to be, this is what you're up against.' Somehow within me I thought okay, I have to be realistic but I have to be hopeful as well.''
Kylie wrote the highly-personal ballad with her musical director Steve Anderson, who in the 1990s was a member of the house music duo Brothers in Rhythm. They are best known for their 1991 single "Such a Good Feeling", which reached #14 on the UK Singles Chart and also topped the U.S. Billboard Hot Dance Club Play chart. Anderson first worked with Minogue was in 1992 when Brothers in Rhythm remixed Minogue's single "Finer Feelings."
Anderson and Minogue originally wrote the song for the singer's 2007 X album, but it didn't make the final cut. However, she did perform it as part of her 2008 'X' world tour.
The black and white music video was shot in Cornwall, England on August 12, 2012. Kylie herself directed it because she had, "always known how I wanted to illustrate the song."
