Edwards said at the planting, which also marked ENA's 25th anniversary: "The trade of plants across Europe is inevitable and the European Nursery Stock Association exists to promote dialogue between the nurserymen carrying out that trade, to promote best practice amongst those nurserymen and to ensure that the legislature we inevitably have to abide by is sensible and appropriate.
"We’re planting trees across Europe to remind people of the importance of our trade and the products we deal in – in this high tech age there still nothing quite so good for the world we live in as plants."
Edwards, Julian Ransom of APL member 4th Corner and HTA horticulture head Raoul Curtis-Machin planted Malus Evereste and Bramley Apple trees, supplied by nursery Frank P Matthews.
ENA simultaneously planted 25 trees across Europe in one day to symbolise the billions of plants produced by European nurseries in the last 25 years and to pay tribute to nurserymen who have cultivated plants.
The HTA hopes to be able to hire out its six new meeting rooms, showroom space and a conference room, as well as use them for its own events.
