The main aim of this paper is to establish how urban environment conditions do influence the development of shrub ornamental plants in terms of their phenology. Spring season phenology of six species of ornamental shrubs and four of trees from an urban area of Muntenia, Romania, was analyzed under the influence of temperature. The analyses were made using correlations and the cold hours accumulated by species were calculated until the flowering bud breaking. The results obtained show that temperature significantly influences the onset of spring phenological phases and their duration. The research will be going on focusing on changes that occur in phenology of species from one year to another, under the influence of variable climatic conditions from year to year, in order to highlight the effect of climate changes on urban phenology.
