Prince Charles wears the same thing to every christening

Eagle-eyed royal fans have noticed a curious detail about an accessory worn by Prince Charles at the baptism of Archie Mountbatten-Windsor.

It turns out the Prince of Wales has been wearing  the same pink flower -  a Dianthus Devon Wizard - to three of his four grandchildren's christenings.

And there’s a super sweet meaning behind the tiny fuchsia bloom Charles pins to his lapel for royal christenings.

"Dianthus is believed to have derived from the Greek words 'dios' meaning God and 'anthos' meaning flower – translating as God's or Divine Flower," Lavender Green Flowers, the florists behind Pippa Middleton's wedding, told HELLO! Magazine.

"Although there is lots of speculation about what these symbolise, a significant one is that they are believed to be the flower for maternal and undying love."

It's a sweet touch, demonstrating Charles' clear adoration of each of his grandchildren, all of whom the Prince of Wales is said to share close relationships with.

Charles, 70, has made a point of repeating the special detail in the last few years, appearing at the christenings of Princess Charlotte, Prince Louis and now Archie Mountbatten-Windsor wearing the bloom on his lapel.

Prince George's was the only christening he attended without the flower as an accessory, however, that’s likely down to the seasons – the Dianthus Devon Wizard wasn't in bloom at the time.

The flowers bloom between June and September, summer months in the UK, but George wasn't christened until October of 2013, so Charles likely couldn't get his hands on one of the little pink flowers.

It is believed the Prince usually plucks them from the grounds of his country home, Highgrove House, where Dianthus Devon Wizard flowers are known to grow.
