Kate Middleton steps out in gorgeous Emilia Wickstead for garden launch with Mary Berry

Beautiful in florals!

Kate Middleton stepped out on Tuesday morning for a surprise appearance to help launch the "Back to Nature" Garden at The Royal Horticultural Society's garden at Wisley in Surrey.

According to Kensington Palace, the new garden includes features from the Duchess of Cambridge's exhibit at the Chelsea Flower Show back in May, including the hollow log and boulders from the waterfall, as well as elements from the RHS Hampton show, like the wildflower meadow.

The royal, who opted for a gorgeous Emilia Wickstead floral dress for the occasion, was joined by "The Great British Bakeoff" star and RHS Ambassador Mary Berry at the event and a number of individuals from the duchess' favorite charities. Taking part in the festivities, the duchess joined children on a tractor ride and showed off the centerpiece of the permanent fixture, a giant wooden treehouse. 

“I really feel that nature and being interactive outdoors has huge benefits on our physical and mental wellbeing, particularly for young children," the royal said back at May at the Chelsea Flower Show's garden opening.
