Alocasia longiloba

A widespread and very variable Southeast Asian Alocasia with arrow-shaped leaves, often dark with pale or silver veins. The species is broad: plants long sold as A. lowii, A. watsoniana, A. korthalsii and A. veitchii are now treated as part of it, and they form a continuum of variation. It grows on rainforest and swamp-forest floors, in regrowth, on boulders, and on exposed cliffs and in ravines at low to medium elevations. It wants warmth, steady moisture and humid, shaded conditions.

Where it grows wild

It grows on rainforest and swamp-forest floors, in regrowth, on boulders in forest, and on exposed cliffs and in ravines. Plants are small to robust herbs, 40–150 cm tall, and grow both on soil and on rock.

Low to medium elevation. Wild GBIF records span 8–1369 m with a median of 90 m, so most are lowland.
