A deciduous shrub or small tree of the Rosaceae family. Native to China, it has been widely cultivated throughout Japan for ornamental and fruit purposes. The trunk grows to about 3m in height, and the leaves are alternate, long lanceolate, about 10cm long, and serrated. In March and April, short-stalked flowers appear singly in the leaf axils at the same time as the leaves or slightly before them. The calyx is covered with soft hairs, and the five petals are pale pink and open horizontally. The fruit ripens in early summer and is juicy and delicious. There are many varieties, including water-nectar peach, white peach, and Tianjin peach, but in taxonomic terms, all peach varieties with hairs are included in the peach category, and those without hairs are called nectarines, P. persica var. nectarina . In addition to the edible fruit, the seeds are used in traditional Chinese medicine as a cough suppressant, the leaves are used as peach leaf tea to treat heat rash, and the dried white flowers are used as a laxative. The fresh flowers are known as the flower for the Girls' Festival. Source: Encyclopaedia Britannica Concise Encyclopedia About Encyclopaedia Britannica Concise Encyclopedia Information |
