Summary In order to breed new miniture camellia cultivar with early flowering property, interspecific hybridization between Camellia japonica L. and C. sinensis was (L.) O.Kuntze conducted. Nine hundred and thirty -five flowers of C. japonica were crossed with 3 cultivars of C. sinensis in 1990 - 1991. Twenty-one interspecific hybrid seedlings were planted to open field in 1993 and their characteristics were investigated for the following selection. The seedling derived from the cross between C. japonica 'Komomiji' and C. sinensis 'Yamatomidori' was finally selected in 1998 and was registered as Camellia Norin N0.1, 'Harumachihime' in 2002. 'Harumachihime' shows the intermediate characteristic plant form between C. japonica and C. sinensis. The flower color pattern of 'Harumachihime' is striated-speckled of pink GHS color chart N0.9504) on a white ground GHS color chart N0.2201). This is the first hybrid with speckled flower color in this cross combination. Flower diameter is approximately 3 cm. The number of petals is 6 to 7. The natural flowering time of 'Harumachihime' is between the beginning of December and the end of April in Mie prefecture. 'Harumachihime' is easily propagated by cutting and has vigorous growth habit.
