Japonica refers to a group of plants, particularly the Camellia japonica, which is a flowering evergreen shrub native to East Asia. Known for its beautiful, large blooms, it is often cultivated for ornamental purposes in gardens and landscapes. The flowers can be red, pink, or white, and they typically bloom in late winter to early spring. In addition to Camellia japonica, the term can also refer to various species of rice, such as Oryza sativa subsp. japonica. This type of rice is characterized by its short, round grains and is commonly grown in East Asia. It is often used in dishes like sushi and rice balls due to its sticky texture when cooked.
