Description and Ethnobotany
| Others - Plant Morphology | Clumping aroid shrub, 1.5 - 2.0 m in height, purportedly first sighted in Papua New Guinea.Leaves very large, with golden yellow petioles and veins, and undulating margins. Inflorescence has yellow spadix and greenish spathe, but florets yield no pollen -- cultivar reported to be sterile.Prefers slightly acidic, well-drained soils rich in organic matter. Takes full sun to semi-shade, but more light deepens the yellowness of petioles and veins. Young plants are greenish, until they grow more leaves. Propagate by division of clump, or underground rhizomes.Large clusters of plants have imposing presence, ideal for imparting sunny tropical look to gardens. Can also be used in large containers. |
