Tamra' was selected in Jeju in 1997 and its open-pollinated progenies were proliferated at the Korea Forest Research Institute in Suwon, Kyungkido. Stability of genetic characteristics was evaluated from 2001 to 2004. The progenies were annually managed with transplanting and 5 to 6 times in weeding. Leaves, flowers, branches and growth characteristics on selected trees were investigated. Results of morphological characteristics showed that 'Tamra' has simple flower in open type of flower and funnel shape in flower type. It has flower diameter of 100.0 mm that is relatively very large as compared with contrastive cultivar, 'Chilbo'. The petal is slightly folded as compared with contrastive cultivar and its eye zone is not spread. Leaf type is in oval shape, and leaf length and width are short (47.1 mm) and narrow (23.8 mm), respectively. Leaf width to width of leaf shoulder ratio having 1.5 is much wider as compared with contrastive cultivar having 1.4. Thickness of leaf, gloss of leaf and density of branch are all medium. Quantity of bloom is in normal condition and changes in the number of flowers by seasons are small, also, its blossom comes into summer. 'Tamra' having large flowers and red color could be useful for a good ornamental and garden tree.
