Queen Elizabeth was overwhelmed when she was gifted a special present on what would have been Prince Philip's 100th birthday.

Her Majesty is a Patron of the Royal Horticultural Society and was gifted a specially-bred rose that has been named in memory of her late husband.

The flower, called the Duke of Edinburgh Rose, was gifted to the Queen on Wednesday the 2nd, but photos have only been released on what would have been the Duke's birthday, the 10th of June.

"Whilst being very poignant, it was also a delight to give Her Majesty The Queen, Patron of the Royal Horticultural Society, the Duke of Edinburgh Rose to mark what would have been HRH The Duke of Edinburgh's 100th birthday and to remember his remarkable life," President of the Royal Horticultural Society, Keith Weed said in a statement from Buckingham Palace.

"The Duke's devotion to raising public awareness of the importance of conserving the natural world leaves a lasting legacy."

The rose was bred by Harkness Roses and has a "deep-ink colour dappled with white lines" and are "perfect as vase flowers".

For every rose sold, the company will donate $5 to the Duke of Edinburgh's Award Living Legacy Fund.

"We are thrilled to introduce this brand-new commemorative rose to remember the remarkable life of The Duke of Edinburgh," managing director Philip Harkness said.

"In buying this rose you will also be giving one million more young people the opportunity to do their DofE Award, so not only is this rose spectacular to look at, but you will also be raising funds for a very worthy cause."
