Dombeya wallichii is a flowering shrub of the family Malvaceae known by the common names pinkball, pink ball tree, and tropical hydrangea.[1]
The plant can grow 20[2] to 30[1] feet tall and has a spread of up to 25 feet. The alternately arranged leaves are heart-shaped with serrated edges. The hanging flower clusters are pink, showy,[2] and fragrant.[1]
It is native to eastern Madagascar. Its natural distribution isn't well understood, but wild specimens were collected from two coastal streamside locations on the eastern coast of Madagascar – at Antalaha on the northeastern coast, and at Mandena on the southeastern coast.[3]
It has been introduced by humans to Cuba, the Dominican Republic, Marianas, Mauritius, southwestern Mexico, Réunion, Thailand, and the Windward Islands, where it has naturalized.
Dombeya wallichii is grown widely as a garden plant.
This species can be crossed with Dombeya burgessiae to produce the hybrid Dombeya × cayeuxii.[1]
