A systematic study on flowering characters of promising flowering tree species in Tarai condition was carried out in and around Pantnagar, Udhamsinghnagar, Uttaranchal to find out the flowering period for effective landscape designing in the region. A total of eighteen common flowering trees were studied year round for their duration of flowering, peak flowering month and flower colour.
