International growers met at a conference in Leiden, the Netherlands, this month, with the UK re-presented by Delamore and Four Oaks Nurseries.
Delamore managing director Wayne Eady said the conference was the first of its kind to bring together plant propagators, distributors and breeders from so many countries.
He said: "There are similar groups working on a national basis but none on a European level.
"The work of the group may include representation to national and European government on plant health topics and plant movement issues. It could also include the development of a standard European quality mark."
He added: "It was really interesting to talk to people with completely different perspectives on broadly the same product.
"Each country appears to have different objectives for its products and each has its own criteria for plant health and plant quality. It was also a useful way of making contact with breeders who would otherwise not have access to certain areas of the world for their products."
The new group will next meet in October, possibly in Barcelona.
