What is Isunoki

Distylium racemosum or Isunoki (scientific name: Distylium racemosum) is native to Japan, the Korean Peninsula, Taiwan and China. It is an evergreen tall tree in the family Hamamelidaceae. It grows in lowland evergreen forests in warm areas of Kanto, Shikoku, Kyushu and the Ryukyu Peninsula. The leaves are infested with aphids (Nipponaphis distychii), which tend to produce large round bumps. Bug bumps contain tannin, which is a dye. The bug bumps will be a whistle. The trees are used for street trees, hedges and windbreaks. Because the wood is hard, it is used for wooden swords, canes, and furniture. The ash is used for pottery. Small, staminous red flowers with no petals bloom in spring.
