The collaborative exhibit at Chelsea 2016 would involve the garden industry, the HTA, the Garden Centre Association (GCA), Love the Plot You've Got, schools and horticulture colleges.
The Sun Flower Square will focus on landscaped front gardens, a living seed catalogue, a schools' home-grown display and a hanging garden. Some 10 seed companies as well as schools, colleges and GCA members are already committed to the project. Lovania may also be involved.
"It would be nice for 80 companies from the trade to represent one of each of my years," said Seabrook. "The plan is that this collaboration will really bring together key players in the industry, both growers and retailers, and highlight not only the variety of plants available in the UK but also the innovative ways in which they can be displayed."
