Alocasia (Elephant Ears & Jewel Aroids)
Alocasia represents an elite genus of sculptural rhizomatous aroids famed for dramatic arrowhead leaves, metallic sheen (Jewel Alocasias), and striking contrasting veins. These tropical rainforest understory specimens thrive in bright, indirect light and chunky, breathable substrate.
Alocasia leaves emerge directly from subterranean tubers/corms rather than vining stems. During dry or cold periods, Alocasias can enter dormancy—never discard a leafless tuber, as it will sprout new foliage once warmth and moisture return.

Alocasia Care at a Glance
Bright indirect light (300–800 fc). Protect from direct sun which scorches delicate foliage.
Allow upper 40% of mix to dry before drenching. Sensitive to cold tap water; use room-temperature water.
Airy chunky aroid blend: 40% orchid bark, 30% perlite/pumice, 20% coco coir, 10% worm castings.
60%–80% RH optimal. High humidity prevents crispy leaf tips and spider mite vulnerability.
