About Clerodendrum quadriloculare (Blanco) Merr.
The bronze-leaved clerodendrum, with the scientific name Clerodendrum quadriloculare (Blanco) Merr., is a medium to large shrub that grows to around 5 meters (16 feet) in height. Its branches and twigs are four-sided. Leaves grow in opposite pairs, attached to stems by medium-length petioles. Leaf blades are oblong, reaching up to 20 cm (8 in) long: the upper leaf surface is green, while the underside is purple. Leaves have rounded bases, wavy margins, and pointed tips. Showy clusters of flowers grow at the tips of shoots. Each cluster holds many individual flowers, each with a slender pink tube approximately 7 cm (3 in) long. The end of each tube has five slender white, bent-back corolla lobes that are about 1.5 cm (0.6 in) long. After flowering, the plant produces ellipsoid capsules that each contain four seeds. The corolla tubes are unusually long, so this species requires specialist pollinators. This plant is native to the Philippines and Papua New Guinea. It has additionally been recorded in American Samoa, the Federated States of Micronesia, Fiji, French Polynesia, Guam, the Marshall Islands, the Northern Mariana Islands, Palau, Rarotonga in the Cook Islands, Samoa, Puerto Rico, Singapore, and Hawaii. It grows in parks and gardens, as well as along road verges, on disturbed ground, in pastures, at forest edges, and in undisturbed forests, where it can outcompete and displace native plant species.
