In order to breed a new, fragrant miniature camellia cultivar, we conducted interspecific hybridization between Camellia japonica L. and C. lutchuensis Ito. We crossed 581 flowers of C. japonica with C. lutchuensis in 1990. Five interspecific hybrid seedlings were selected for planting in an open field in 1993, and their characteristics were investigated to guide subsequent selection. One seedling derived from the cross between C. japonica 'Komomiji' and C. lutchuensis was finally selected in 1998 and was registered as Camellia Norin No.4 'Himenoka' in 2003. The flowers of 'Himenoka' emit considerable amounts of fragrance, as is the case for C. lutchuensis. The pattern of flower color in 'Himenoka' is striated-speckled, with purplish-pink on a pinkish-white ground. This is the first hybrid with speckled flower color that has been observed in this particular cross. Flower diameter is approximately 5 cm, and the number of petals averages 6. The natural flowering time of 'Himenoka' is between the end of February and mid-March in Mie Prefecture. 'Himenoka' is easily propagated by means of cuttings, and grows vigorously.
