The current investigation aimed to study the effects of environmental and landscape conditions on some ornamental plants used for landscape planning in some North Coast Villages of Egypt during the successive years from 2003 to 2006. Three resorts at the North Coast of Egypt; Costa Dell Sol, GreenBeach and Marina (phase 5), were chosen to carry out this study. In each resort, certain vegetative measurements were conducted to determine the growth and development of some ornamental plants growing at the distances of 100 and 500 m from the seashore. These measurements were carried out at the four climatic seasons (autumn, winter, spring and summer). The evaluated plants in this work were Vinca rosa L., Acalypha wilkisiana Muell.and Erythrina indica. The obtained results showed significant differences in all investigated characteristics between the three resorts. The evaluated plants growing in Costa Del Sol resort showed the best values of plant height, plant diameter, number of main branches and stem diameter followed by Marina. GreenBeach resort presented the lowest values of the investigated characteristics. Additionally, the tested plants grown at the distance of 500 m from the seashore showed better results than those grown at the distance of 100 m from the seashore. The summer gave the best results of all investigated characteristics when compared with other seasons. Most of the interaction treatments represented significantly effects in all investigated characteristics. Generally, the plants growing in Costa Del Sol resort at the distance of 500 m from seashore and in summer, showed the best values of plant height, plant diameter, number of main branches and stem diameter.
