Natural grace! Kate Middleton is wowed by stunning giant butterfly designed by 12-year-old Blue Peter contest winner as the sculpture is unveiled in Duchess's Back To Nature show garden

  • The Duchess of Cambridge, 37, appeared on CBBC's Blue Peter this evening 
  • Earlier this year she launched her Royal Garden Competition for children 
  • The winning piece has been placed in her Back to Nature Garden at RHS Wisley 
  • The royal announced the winner and praised her butterfly themed piece 

This is the moment that a stunned Duchess of Cambridge unveiled the winner of Blue Peter's Royal Garden Competition , an enormous butterfly sculpture made from wood and recycled metal.

Kate, 37, appeared on the show and hailed the design by Jessica, 12, which will now feature in the royal's 'Back to Nature' garden, at RHS Wisley in Surrey. 

Jessica's design featured a twisted thorax sculpted from wood and a trellis of recycled metal in the shape of butterfly wings for brightly coloured clematis flowers to grow over.

At its centre hangs a set of wind chimes, and the first flowers have already started to grow over its wings.  

The duchess launched the Royal Garden competition in June - calling for Blue Peter viewers to design a sculpture featuring natural materials for the garden she designed for the Chelsea Flower Show. 

The photo was part of a gallery of video and images released by Kensington Palace to mark Kate's Blue Peter appearance. This image, showing the Kate at the opening of the Back to Nature Garden at RHS Wisley this month, was also shared on the official Instagram account

The official account of The Duke and Duchess of Cambridge, shared a series of snaps from the day, showing Kate looking radiant while chatting with the winner and runners up. 

She wore an elegant pastel blue floor-length midi dress by Emilia Wickstead, one of her favourite labels. 

It was emblazoned with pink roses which she teamed with a matching belt at the waist. 

She wore her brown tresses loose around her shoulders and paired her outfit with a pair of chic bronze earrings and a natural make-up look. 

Hundreds of entries were whittled down to just 30 by Blue Peter's judging panel, which included Kate and the Royal Horticultural Society's youth ambassador George Hassell.

The winning design was brought to life by professional crafts people over the course of a week.

Fall for florals like the Duchess in a midi dress by Emilia Wickstead

The Duchess of Cambridge unveiled a new version of her Chelsea Flower Show garden today, and of course she picked florals for the occasion. She's a pro at literal dressing!

Her chic midi length shirt dress is by one of her all-time favourite designer labels, Emilia Wickstead, and we love the combination of the colours. The pretty pink rose print against the pale blue background is blooming beautiful! The seersucker fabric is very unusual, and the belted waist creates a gorgeous silhouette too.

Unsurprisingly, the 'Aurora' dress has now sold out, but click (right) to get a closer look at this exclusive dress at NET-A-PORTER.

Or emulate Emilia Wickstead on a budget with the help of our edit below. And don’t forget that florals don't have to just be for spring/summer - any one of our options would be perfect as we head into autumn!

Jessica, from Lincolnshire, was speechless when she saw her creation for the first time, saying only: 'That's really cool.'

Kate was equally impressed, saying: 'Oh wow, look at it - it's amazing. It's enormous.'

Jessica replied: 'Yes it's taller than I am.' 

The Duchess added: 'It's going to be so lovely year after year coming back to see how it's growing and how it's all developing.'

Kate is the proud owner of both a gold Blue Peter Badge and a new green Blue Peter badge - which is awarded to champions of the environment, conservation and nature.

She was given her rare gold badge after appearing on the show with the Duke of Cambridge in 2017, receiving the honour for their work on children's mental health.

The garden competition was part of the duchess' ongoing mission to encourage children and families to get back to nature, and highlight the positive impact that nature and the environment can have on childhood development.

Her woodland wilderness garden at the Chelsea Flower Show in May featured a high-platform tree house, a rope swing, a rustic den and a campfire as well as tree stumps, stepping stones and a hollow log for children to play on.

George, Charlotte and Louis were taken on a visit to see it by Kate and William, and the Cambridge children spent around an hour playing in its stream and running around its woodland paths.

The winning sculpture was created from wood and recycled metal and featured two huge geometric butterfly wings surrounded by pretty purple clematis flowers. 

Kate, 37, who first appeared on the show in June, joined Jessica, the winner of their Royal Garden Competition at The Royal Horticultural Society's garden at Wisley in Surrey to take a look at the winning sculpture.
