The National Plant Show is a cooperative venture that should lead to more cooperation in UK horticulture, says HTA president Stan Green.
He said the show, now in its fifth year (Stoneleigh 24-25 June) was a "model for cooperation".
He added: "Opinions like 'don't be so naive, cooperative ventures rarely work in UK horticulture' can prevail. I don't agree with that. Cooperation isn't easy but I think we need to cooperate more in our businesses."
Green said this could be in transport efficiencies, collectively addressing customer service demands, examining macro marketing strategies and exploring new areas such as environment, media engagement and localism "can all be tackled better and with critical mass".
More than 100 nurseries with UK bases will exhibit.
Among exhibitors, Allensmore will launch 30 new plants, Blackmore will reveal its link with Lubera, Forest Edge will launch Calluna vulgaris 'Galaxy', John Richards will launch Lonicera 'Rhubarb and Custard' and Seiont will launch a host of new heuchera.
Howard Nurseries and Glendale will be first-time exhibitors.
