Description

This distinctive small tree has columnar stems and huge umbrella like leaves. It can grow from 5 – 10 m (15 – 30 ft) tall with round leaves 60 – 100 mm (1 – 4 in) long. Stem attached to the middle of the leaf, rather than the edge. Pink, petal-less flowers form in clusters near the base of the leaf stalk. Young plants may superficially resemble Hawaiian taro (Colocasia esculenta).

Impacts

On the island of Hawai’i, bingabing was seeded from airplanes along with many other weedy forestry species near Hilo after a fire. Today, it lines roadsides, gulches, and disturbed forests in the vicinity. Its large leaf structure creates a dense growth that can crowd and shade out other vegetation.

Distribution

Bingabing is only found on Oʻahu and the island of Hawaiʻi.

Macaranga tanarious: This relative of bingabing is another invasive pest that has already escaped into the wild on Oahu, Maui and Kauaʻi. It can be distinguished from bingabing by its smaller leaves (60-100 cm or 24-40 in) and pale green to yellowish green calyx (tough outer petals that protect the bud before it opens).
