  • Leaves: Broadly ovate, heart-shaped, up to 30 cm long, with entire or slightly lobed margins and a velvety texture.
  • Flowers: Large, tubular, pale violet to purple, arranged in terminal panicles that appear before leaf emergence.
  • Fruit: Ovoid, woody capsules containing numerous small, winged seeds dispersed by the wind.

Applications

Cultivation of this tree yields lightweight, strong, and warp-resistant timber, which is highly valued for crafting traditional Japanese cabinetry and musical instruments. Its rapid biomass production makes it a candidate for agroforestry and land reclamation projects.

In urban environments, it serves as a dramatic shade tree, though its aggressive growth requires careful management. The leaves, rich in nitrogen, are sometimes used as green manure to improve soil quality.

Interesting facts

In Japanese tradition, planting this tree when a daughter is born is a long-standing custom, ensuring that the wood can be harvested to make a chest of drawers for her wedding dowry. The leaf of this genus is also featured on the official seal of the Prime Minister of Japan, representing authority and government.
