Clarke & Clarke Secret Garden Maymont Midnight Wallpaper. Maymont is a trellis wallpaper design, it is anything but your standard garden trellis. Bursting with garden life and colour, it is modern and fresh. With its name taken from Maymont Garden, Virginia, the garden served as inspiration for the trellis design, while retaining a lovely English feel. This design encapsulates the theme of a secret garden, as nature winds its way up the geometric structure.
