The festival, aimed at buyers, growers and retailers, will feature introductions, bedding, perennials, shrubs, trees and merchandising to concepts, with plants from New Forest Plants and New Place Nurseries, which are part of the Roundstone Group that was taken over by Newey in January 2015.
Ornamental bedding including unique FairTrade poinsettia will be on display from the Red Fox stable, produced by Dummen Orange, the largest cutting producer in the world.
The organisation, formerly known as Dummen Group, is now part of the DNA Green Group and recently underwent a rebranding exercise to bring all of its operations under one global brand - Dummen Orange.
"This is something we connect to very strongly," said Newey Group managing director Alex Newey. "We have undertaken significant and strategic growth over the last 12 months and in doing so created a unique vertically integrated group of companies. In addition to broadening the portfolio, the Newey Group is driven to encourage fresh and modern thinking in the world of commercial horticulture.
"Dummen Orange reflects the importance placed on its rich heritage in Holland, its family and its people. Commitment to its values and its passion for excellence is widely recognised and Young Plants actively embraces these principles as UK distributor for the group."
There will be a growing media and Aero NT tray display from Omni Solutions, which is part of Newey.
Kotterheinrich will be bringing a display of hydrangea. The company produces seven million each year.
