The leaves are an elongated heart-shape, with pronounced rear lobes, deep red on the undersides and glossy, dark green on the upper side, with pronounced light green veins.

How to grow

Cultivation

Under glass, grow in an open, ericaceous, well-drained, but moisture-retentive mix, which can include, ericaceous peat free compost, lava rock or pumice, fine fir bark and leafmould or chopped sphagnum moss, choosing a position in bright but diffused light. These plants prefer growing in a year round temperature, between 18-25C. During the growing season, allow the top 5cm of the compost to become just dry, before thoroughly watering the compost. Use clean rainwater at room temperature, if the tapwater in your area is hard, to avoid turning the compost alkaline, which would eventually become toxic to the plant. Avoid plants sitting in water which can cause the roots to rot. Apply a liquid houseplant fertiliser monthly during April to September. Water may be required less frequently in winter, when growth slows right down, and stop feeding until the spring. Repot every 2-3 years. See Alocasia and houseplant cultivation for further advice

Propagation

propagate by division once clumps are produced, or by division of the rhizome, potting the sections up individually to root and grow on
