And in Europe I think you have to give a plant a clone name to enter an exibition. The vendors thereby get clone name on all their exibition plants. And as the same plant can be awarded several times by different society a plant can have several Europeen awards... Plants can even be handed in and be awarded at the same show but in different years (in Europe).

Though I have only seen the AOS award mentioned when plants are sold, not the Europeen awards.
