This work aims at developing a system able to identify the plants grown by a specific nursery, to distinguish them by the others. This system will be proposed in particular for the identification of the roses. To provide a secure identification of the roses, a solution concerning the integration of a Passive RFID tag in the plant at the grafting time has been developed together with the device able to read the used tags. An accurate analysis of the industrial RFID solutions allowed us to identify the UHF tags as the most suitable one, as for the grafting process, as for the electromagnetic interaction with the growing plant around them.
