The present study was carried out in a Phenological Garden located in central Italy Perugia Umbria Region which contains indicator species common to all International Phenological Gardens. The aim of this study was to determine and analyse the average trends of development of eight plant species and their phenological adjustment to the Mediterranean environment over a nine-year period 1997-2005 . The results of the statistical analyses show a strong relationship between the temperature trends and vegetative seasonal evolutions interpreted by phenological data for all the species considered. Moreover it was demonstrated that the plants studied may approach or close completely the timing gaps eventually created during the first phenological phases adjusting thus the beginning of subsequent phenophases. phenology garden climate trends Mediterranean Résumé - Recherches sur la phénologie de différentes espèces décidues sous climat méditerranéen.
