Beckham and Harper at Chelsea Flower Show!

Sir was all smiles as he posed with daughter Harper and the flower named in his honour on Instagram on Tuesday. 

The former footballer, 51, unveiled the rose named after him at the garden he designed alongside on Monday. 

It was his daughter Harper's idea to name the Sir David Beckham Rose, in a touching tribute to mark her father's 50th birthday last year, with its official launch a highly anticipated moment of the star-studded day one at the show. 

Posing at their £12 million Cotswold property, David and Harper, 14, crouched down next to the stunning rose bush in their luxury green house. 

The ex England player showed off his tattooed arms in a short sleeved grey T-shirt while the teenager stunned in a khaki coat.

The English shrub rose with luminous white flowers is said to have 'exceptional vigour' and a complex fragrance with hints of banana, clove and myrrh.

Brits can adorn their own gardens with the variant after it became available to buy, from today, through celebrated rose breeder David Austin's Shropshire plant centre and from selected stockists.

For each £27.50 rose sold, £2.50 will be donated to The King's Foundation, which was set up by the monarch in 1990 to create sustainable communities and now boasts Sir David as an ambassador.

The public can also catch a glimpse of the rose growing among the King's Foundation Curious Garden, an exhibition display designed with input from Sir David, the King and broadcaster Alan Titchmarsh.

The trio collaborated over their shared love of horticulture and desire to encourage the nation to 'discover the joy of getting curious about gardening'.

At the heart of the new garden is an oak-framed building, which represents a museum of garden curiosities.

A framed newspaper cutting of the King's 1995 Christmas card hangs on the wall of the shed in the garden, which shows the King, then Prince of Wales, sitting on a bench in his garden at Highgrove with his two sons Princes William and Harry standing inside giant flower pots.

Four gnomes were also snuck into the shed after the Royal Horticultural Society (RHS) lifted a ban on them this year, a move which would likely bring joy to the King who is said to humorously move around some of his own.

Under the vision of head designer Frances Tophill, the display also features a vegetable patch and beehive, inspired by the King and Sir David's shared enthusiasm for beekeeping and producing natural honey, as well as the newly-named rose.

Key plants among the display include delphiniums, known to be a favourite of the King's, wheat, pistachio and mulberry.

As she was shown round the garden, the Queen, wearing a dress by Fiona Clare and a bee brooch, told Titchmarsh: 'This is so nice, it's so natural'.
