Hibiscus syriacus (scientific name: Hibiscus syriacus) is a deciduous tree belonging to the family Malvaceae. Also known as Hachisu, Mokuge. In addition to being widely planted as a garden tree, it is also indispensable as a tea flower in summer.


The Japanese name is "Mukuge". Even one character of '槿' is read as 'Mukuge', but it is often written as 'Mukuge' in Chinese. Also, in "Ruiju Nyogisho," he is described as 'Kihachisu,' and is also called 'Kihachisu,' or simply Hachisu. There is a theory that morning glory, which appears as one of the seven autumn herbs in "Manyoshu," refers to Mukuge, but this is not certain. The red-bottomed variety with a single white flower and a red center is also called 'Soutan Mukuge' because Sotan SEN liked it. In Chinese, it is called ``Moochin, Mokukin'', and in Korean, it is called ``무궁화'' (Mugunhwa), and ``Mokkun''. The common English name rose of Sharon is taken from the English equivalent of "rose of Sharon" in the Song of Songs of the Old Testament written in Hebrew.


It is native to China and is cultivated as an ornamental. It is widely planted mainly in garden trees, roadside trees, and parks. Even in the Middle East, it is often seen planted as garden trees and park trees in major cities such as Cairo, Damascus, and Tel Aviv. It was introduced to Japan long ago and is thought to have been planted already in the early Heian period. It grows wild in warmer areas.

Morphology and Ecology

Large deciduous broadleaf shrub. The height of the tree is about 3-4 meters (m). The leaves are alternate, ovate to ovate-rhombic, shallowly 3-lobed, and have coarsely serrated edges. The flowering season is from summer to autumn (July to October). It bears beautiful flowers of various colors such as white and pink at the base of the leaves at the tip of the branch. Because it is a kind of hibiscus, the flower shape is similar. The flowers are 5 - 10 centimeters (cm) in diameter. The 5 petals are slightly overlapped, many stamens are attached, and the pistils protrude long. Flower buds are formed one after another on elongated branches from spring to autumn of the year. The flower is a one-day flower, blooming in the morning and withering in the evening. It is usually single-flowered, but there are also double-flowered cultivars. The fruit is a capsule, egg-shaped, about 2 cm long, densely covered with star-like hairs, and splits into five when ripe to expose the seeds. The seeds are flattened, kidney-shaped, larger than those of Hibiscus, and densely covered with long hairs along the dorsal edge.
