? We invite you to take a look at the Duchess of Cambridge's "Back to Nature" Garden!

The Woodland Wilderness Garden aims to bring people back to nature and highlight the benefits of the natural world on our mental and physical well-being.

In front of the @The_RHS garden unveiling, the Duchess of Cambridge said: "In recent years, I have focused much of my work on the early years and on the role they play in future results. . I believe that spending time outdoors when you are young can play an important role in making children happy and healthy adults. Among the features of the #ChelseaFlowerShow garden are:

1. A swing suspended under the centerpiece of the garden, a high-platform treehouse, which encourages creative play and discovery for all generations.

2. The high-deck treehouse is inspired by a bird's nest or an animal and is a wonderful place to retreat and look through the trees. The cabin is made of chestnut, hazelnut, deer horn oak and larch nest.

3/4. The garden aims to inspire interactions with the natural environment through its multisensory plant system, green and blue. The garden will be filled with incredible edibles, plants for craft activities, forest scents and a wide range of plants, shrubs and trees of varying heights and textures.

The garden is part of Her Royal Highness's ongoing work on early childhood development and her mission to support efforts to give every child the best possible start in life.

The Duchess is committed to placing early childhood development at the heart of her work in the coming years and she is convinced that giving children the opportunity to spend time outdoors can play an important role.

90% of our adult brains are developed before the age of 5 and what a very young child experiences directly affects brain development.

That's why I think it's so important, whether we're parents, caregivers, or family members, we really spend quality time with children and babies from an early age.

I really think that nature and being interactive outdoors have tremendous benefits for our physical and mental well-being, especially for young children.

The #RHSChelsea Garden Back to Nature is a natural and creative place where they can play.

I really hope that the wood that we have created, as part of a broad collaboration, really inspires families, children and communities to go out, enjoy nature and the outdoors and move from quality time together. #ChelseaFlowerShow
