Plant Description

It is a deciduous, fast-growing tree that can reach up to 4.5 m in height within the first year of planting, and can grow up to 25 m in total height.

Leaves are large, heart-shaped, and velvety due to dense hairs on both surfaces. They are oppositely arranged on the stem. The leaf margin is entire, and the leaf tip is pointed.

Flowers are large, trumpet-shaped, and fragrant. They are pale violet to lavender in color, arranged in showy panicles at the ends of branches. Flowering occurs before leaf emergence.

Fruit is a woody, capsule-like structure, containing numerous small, winged seeds. The capsule is oval-shaped and brown when mature.
