Alocasia lauterbachiana

Purple sword

A tall New Guinea Alocasia with narrow, upright, scalloped-edged leaves up to about 1.5 m, dark green above and purplish beneath. It grows in lowland rainforest in northern New Guinea and the Bismarck Archipelago, especially along river edges and forest edges. That gives it more light than a deep-shade aroid. It is one of the easier alocasias: warm, bright-shaded and evenly moist all year.
