Alocasia is a genus of broad-leaved rhizomatous or tuberous perennials from the family Araceae. There are 79 species native to tropical and subtropical Asia to Eastern Australia and widely cultivated elsewhere.
The large cordate (Heart-shaped, with the petiole or stem attached to the cleft) or sagittate (Arrowhead-shaped) leaves grow to a length of 20 to 90 cm on long petioles. Their araceous flowers grow at the end of a short stalk, but are not conspicuous; often hidden behind the leaf petioles.
Your Alocasia is well suited to warmer areas in your home but not in direct sunlight.
Water regularly but allow the plant to dry out slightly between watering's. Keep potting mix dryer during the cooling months. Adding fertiliser to the weekly watering will keep it flourishing.
