RHS Chelsea Flower Show returned from 22 to 27 May, with gardens from Cleve West, Sarah Price, Tom Massey, Charlotte Harris and Hugo Bugg, Chris Beardshaw and many more.

While other gardens planted many 'edimentals' - ornamental plants that you can also eat.
The winner of Best in Show was the Charlotte Harris and Hugo Bugg's Horatio's Garden, while Chris Beardshaw's garden for Myeloma UK won gold, alongside Cleve West's Centrepoint Garden, Sarah Price's Nurture Landscapes Garden and Jihae Hwang's garden for Hoban Cultural Foundation.
