The Floral Marquee Innovation Project is an RHS initiative encouraging nurseries to use more creativity in their plant displays.
The project gives four nurseries the chance to showcase a themed display in the Floral Marquee at the festival, which runs from May 7 - 10.
Project mentor Darryl Moore said the competition was about breaking away from tradition display formats and moving towards exhibits, which reflected the contemporary, design-savvy world.
Moore added: "It provides visitors with inspiration for using plants in new ways and something different to come back and see at shows each year."
One of the nurseries involved, Avon Bulbs, has based their presentation around their bulb posting service. Celebrating the gift of a bulb, visitors will be invited to post a package of bulbs from the iconic red post box, which will mark the gift of hope, optimism and new life.
Avon Bulbs owner Chris Ireland-Jones said: "When the RHS approached us we welcomed the chance to develop our displays and explore different and original ways of presenting our plants. We are pleased with the results and excited, albeit a little trepidatious to hear what the public (and RHS judges) think."
The remaining nurseries are Oska Copperfield, with a display themed on the Mad Hatter’s tea party; Floyds Climbers & Clematis exhibiting a shipwreck overrun with climbers; and Drointon Nurseries, presenting a twist on the traditional Auricula theatre.
