To determine flowering habit in the genus Camellia, differences in patterns of flower bud formation in 69 cultivars of 10 species and 3 hybrids were characterized. When ranked by the quantity of flower buds produced, a group of species from subtropical areas was the highest, followed by C. sinensis, then C. sasanqua and a group of species presumably derived from hybridization (C. hiemalis, C. wabisuke, and C. vernalis), and finally C. japonica. From a small sample of available hybrids, it appeared that flower bud production in hybrids is variously intermediate to the parents. In order to examine the flowering characteristics of shoots, they were classified into three types of vegetative shoots according to vigor, and into four types of flowering shoots ranging from those with only terminal flower buds to those with buds in both the terminal and lateral positions. C. sasanqua and C. hiemalis tend to produce more flower buds on longer and more vigorous shoots while C. japonica was found to produce most flower buds on shoots with intermediate growth. Bud production in the lateral positions was the lowest in C. japonica. The species which were considered to be hybrids such as C. wabisuke and C. vernalis showed flower bud production pattern that were intermediate between C. sasanqua and C. japonica.
