Alocasia cuprea is a species of flowering plant in the family Araceae. It is commonly referred to as “copper alocasia” due to the distinctive metallic sheen of its foliage.
Taxonomy

The specific epithet cuprea is derived from the Latin cupreus, meaning “copper‑colored,” a reference to the plant’s characteristic leaf surface.
Description
Alocasia cuprea is a herbaceous perennial that typically attains a height of 0.5–1.5 m. The plant produces a rhizomatous root system from which erect, petiolate leaves arise. Leaves are broadly cordate to ovate, ranging from 20 cm to 40 cm in length, with entire or shallowly lobed margins. The adaxial (upper) surface is glossy dark green, while the abaxial (lower) surface exhibits a metallic copper to bronze coloration, often described as “iridescent.” The inflorescence consists of a spathe and spadix typical of Araceae; the spathe is usually greenish‑white, enclosing a fleshy spadix that bears numerous tiny, unisexual flowers.
Distribution and habitat
The species is native to the tropical rainforests of Borneo, principally in the Malaysian state of Sarawak. It occurs in lowland and foothill forest understories, preferring humid, shaded environments with well‑drained, organic‑rich soils. Precise limits of its natural range are not fully documented; additional occurrences in neighboring regions have not been conclusively verified.
Cultivation
Alocasia cuprea is cultivated as an ornamental foliage plant in both private collections and commercial horticulture. Successful cultivation generally requires conditions that mimic its native habitat: high humidity, bright indirect light, and temperatures between 18 °C and 28 °C. The plant is sensitive to cold and prolonged exposure to direct sunlight, which can cause leaf scorch. Propagation is commonly achieved via division of rhizomes or by leaf cuttings under sterile conditions.
Uses
The primary use of A. cuprea is decorative; its striking foliage makes it a popular choice for interior plant displays and specialty collections of tropical plants. No documented medicinal, culinary, or industrial applications are widely recognized.
Conservation status
As of the latest assessments, Alocasia cuprea has not been evaluated by the International Union for Conservation of Nature (IUCN). Consequently, its conservation status remains undetermined.
Notes
- Accurate information on the full native distribution and potential threats to wild populations is not confirmed.
- Taxonomic revisions within the genus Alocasia are ongoing; synonymy and phylogenetic placement may be updated in future systematic studies.
