Abstract
Trees in the landscape has strong character in color which is performed by flower, however flower appear only in certain period. This study aims to determine the flowering period of trees, climate factors that affect period of flowering, and its usage in planting plan. This study was conducted for 12 months from September 2013 to August 2014 using 10 species of flowering trees. Based on the observation, all species showed peak flowering in certain month while 8 species namely Caliandra surinamensis, Callistemon citrinus, Cassia siamea, Cerbera mangas, Jacaranda acutifolia, Lagerstroemia speciosa, Plumeria rubra, and Spathodea campanulata showed flower along the year, and 2 species namely Samanea saman and Tabebuia caraiba showed no flower in certain month. Based on analysis of percentage of flowering showed a significant correlation with climate factors. Rain days significantly affected flowering of J. acutifolia and S. saman, maximum temperature affected flowering of P.rubra, minimum temperature affected flowering of Samanea saman, length of irradiation affected flowering of Cassia siamea, P.rubra and T. Caraiba and relative humidity affected flowering of P.rubra and T. caraiba. Aesthetic value of site can be increased by using more species with different in period of flowering to show flower blooming along the year.
