About this species

Although its Latin name, Styphnolobium japonicum, implies that the pagoda tree is a Japanese plant, it is in fact native to China. The species was first described under the name Sophora japonica, based on cultivated material from Japan, and thus the choice of species name. It was introduced to Britain in 1753 by the famous nurseryman James Gordon, and it is believed that one old veteran specimen tree at Kew is one of an original five planted in the Gardens in 1760. They are thought to have been the first in the country. Collectively these original trees are known as Kew's 'Old Lions'.

Medicinal Uses

Styphnolobium japonicum is used in traditional medicine in Asia, where the flower buds are used for their haemostatic and astringent properties. Despite their strong purgative properties, extracts of the leaves and fruits were once used in China to adulterate opium.
