For purpose of establishing the data of characteristics of caladium varieties, twenty-six varieties of C. bicolor and five varieties of C. pictulantum were used to investigate the tuber weight, leaf number, plant height, leaf shape and the speed of emergence rate. From the data we collected, there was no obvious correlation in tuber weight, leaf numbers and plant height between same or different varieties. Heavier tubers were not necessarily had more leaf numbers or owned higher plant height. BA treatment increased the leaf numbers, but not as much as terminal bud removal. GA3 treatment could raise the flowering rates and flowering numbers as well as induce the leaf shape into narrow.
