Mucuna macrocarpa
Japanese Name: イルカンダ
Chinese Name: 血藤
English Name: Rusty-leaf Mucuna
Origin: Southern China, Taiwan, Malaysia, Amami Islands to Okinawa Islands, India
The Japanese name Irukanda comes from the Okinawan dialect, where Iru means “color” and Kanda refers to “vine.” This species is common in the forests of Yambaru. From March to May, its flowers bloom in dense clusters, creating a breathtaking sight that has earned it the nickname “Chandelier of the Forest.”
The Rusty-leaf Mucuna has years with abundant flowering and others with fewer blooms. In 2025, it was a peak blooming year. At the forest trails of Daisekirinzan (ASMUI), visitors can enjoy the spectacular sight of these flowers in full bloom overhead.
