Flower power! Duchess of Cambridge is radiant in Erdem frock at the Chelsea Flower Show

The Duchess of Cambridge gained a royal seal of approval for a her Back to Nature Garden by her grandmother–in-law the Queen at the Chelsea Flower Show this evening.

Mother-of-three Kate swapped her casual culottes for an elegant floral maxi dress as she attended the event in the grounds of the Royal Hospital Chelsea with husband Prince William.

Kate looked stunning in an appropriate Erdem frock as she joined other members of the Royal Family to showcase her Back to Nature garden designed with children in mind.

Meanwhile the monarch looked radiant in a lime green coat teamed with white gloves and a green and purple floral dress.  

Earlier today Kate, 37, dressed down in a white blouse and practical culottes for a visit to her project, which will be open to the public tomorrow, and got her hands dirty as she joined a group of schoolchildren for a fireside chat and outdoor activities. 

Kate’s magical garden features a tree house, waterfall, rustic den and a campfire as well as tree stumps, stepping stones and a hollow log for children to play on.

As the trio discussed the greenery and blooms on display, the Queen remarked the couple were looking ‘very tidy’, to which William replied: ‘Well, I’ve smartened up.’

The mother-of-two, 54, looked effortlessly stylish in a floating green floral dress, having scooped back her blonde locks into a chic bun.  

During his visit, the Queen embarked on a tour of the gardens and the lavish displays. First on her list was the RHS Back to Nature Garden, co-designed by her granddaughter-in-law the Duchess of Cambridge, which aims to encourage all generations to connect with nature. 

She will then take in the RHS Bridgewater garden, heralding the creation of the RHS’s new garden in Salford, in which they will bring back to life the historic gardens of Worsley New Hall.

The Queen will also pay a visit to the Greenfingers Charity garden; a fun, interactive and uplifting space where seriously ill children, their families and friends can come together for play, relaxation or quiet reflection. 

Finally, the monarch will view the work of the National Association of Flower Arrangement Societies, which is celebrating its 60th anniversary with displays on the theme of friendship.

Kate appeared in excellent spirits earlier today as she gamely roasted marshmallows, climbed a tree house and helped make boats from reeds during the hands-on outing.

Her visit comes a day after the Duke and Duchess of Cambridge shared snaps of their own children enjoying a sneak peek of the space.

Established in 1913, on the grounds of the Royal Hospital Chelsea in London, the RHS Chelsea Flower Show has become one of the world’s greatest showcases for horticultural excellence, attracting visitors and exhibitors from across the globe.

Since its beginning, the show has gone from strength to strength. It has grown from 244 exhibitors in 1913 to over 500 today, including gardens, nurseries, floristry, educational displays and trade stands. Today the show attracts 168,000 visitors.

The Show is organised by the Royal Horticultural Society, of which The Queen is Patron. The Society was founded in 1804.

Kate says she ‘hopes her garden inspires families to enjoy nature’

The Duchess of Cambridge has urged families to make the most of nature.

A short clip released by Kensington Palace, the Duchess said parents should spend as much ‘quality time’ with their children at a young age as possible to help their development, particularly outdoors.

She said: ‘I really hope this woodland that we have created here really inspires families and kids and communities in general to get outside, enjoy nature, enjoy the outdoors and really spend quality time together.’

She added: ‘There’s an amazing fact that I learned recently that 90 per cent of our adult brains are developed before the age of five and what a child experiences in these really early years directly affects how their brain develops.

‘That’s why I think it’s so important that all of us, whether we are parents or carers or family members, really engage in quality time with our children and babies from a really young age.’
