This plant has gained the Royal Horticultural Society's Award of Garden Merit.[4] It is used in Japan as an astringent and a dyeing agent. The bark contains (−)-catechin 7-O-β-d-glucopyranoside and (+)-catechin 5-0-β-d-glucopyranoside.[5]
Uses
Known as Sharinbai (車輪梅) in Japan and as Techigi in Amami Oshima, this plant is used to create a dye to create the highly valued Ōshima-tsumugi kimono. The bark of the tree is chopped into chips and boiled for over 10 hours. This tannin rich decoction serves as a dye for the silk threads. After dyeing, the threads are then dyed in mud from paddy fields rich in iron content for post-mordanting until they turn black. [6][7]
Additionally, due to its resilience to drying and air pollution, Sharinbai trees are planted along roadsides. Their glossy evergreen leaves make them suitable for garden planting, enduring well against frequent pruning.[8]
