Phormium 'Blondie', Hydrangea 'LA Dreamin', Veronica 'Pink Passion' and Agapanthus 'His Majesty' will also feature at the show, held on June 20 and 21 at Stoneleigh Park in Warwickshire.
New product development manager Ben Gregory said: "This year we are excited to be entering seven new products including Morus ‘Mojo Berry’, which is a revolutionary new dwarf variety of Mulberry that fruits at a young age".
He added: "Morus ‘Mojo Berry’ also won the 2017 Chelsea Flower Show’s Best New Plant. It was marketed at Chelsea as Mulberry ‘Charlotte Russe’, but will be launch commercially as ‘Mojo Berry’."
Suttons has 37,000 plants to be released in September and has an exclusive on the Japanese-bred plant for a year. The Mojo Berry name will be used elsewhere in Europe. Royal warrant holder Suttons is using the Charlotte name in marketing to give a royal angle, with a link to Princess Charlotte, daughter of the Duke and Duchess of Cambridge.
Agapanthus ‘His Majesty’ was bred by Rod Richards of New World Plants in Herefordshire.
