Alocasia macrorrhizos
Giant Taro
Giant Taro is a large plant with huge upward-pointing leaves that have a distinctive arrowhead shape. On the underside the veins are prominent and raised. This foliage creates a very exotic and tropical atmosphere and as the plant matures it forms a thick brownish trunk. It is however not hardy in the normal UK sense of the word and although it can be overwintered outdoors in some very favoured locations, most exotic gardeners tend to dig them up in autumn and bring them indoors.

Planting
From Early Spring TO Early Spring
In temperate climates, Alocasia is usually grown in a heated greenhouse or as a conservatory plant. Alocasias need rich soil that is moist (not saturated) but well-drained. Plant in partial shade. Indoors, grow in filtered light. Provide high humidity. In warm climates, similar to their native humid and tropical Southeast Asia, elephant ears will grow as perennials. In cooler areas they will need to be replanted each year.
