About Alocasia korthalsii

Alocasia korthalsii is a jewel Alocasia species endemic to Borneo. It grows in shaded, humid rainforest floors, often on leaf litter over rocky soil, with arrow-shaped (sagittate-cordate) foliage. The leaves have a velvety, matte dark forest-green upper surface with contrasting light silver-green primary veins. The undersides are deep maroon-red.

Before You Buy

Species-specific things to check when evaluating a listing

  • Check both sides of the leaf: the upper surface should be matte dark forest-green with silver-green veins, while the underside should be deep maroon-red; a plain green underside suggests a different plant
  • No recorded market price exists for this species yet; treat any quoted price as the seller's own estimate
  • Confirm the leaf shape is sagittate-cordate (arrow/heart-shaped) with a velvety, thick, paper-like texture consistent with the described form
  • As a dwarf, slow-to-moderate growing understory species, expect gradual size increase rather than fast establishment

Two-Toned Foliage

Korthalsii is one of several Bornean jewel Alocasia species where the underside of the leaf does as much identifying work as the top: a matte, velvety dark forest-green surface with silver-green veins on top, and a deep maroon-red underside that most sellers photograph less often than the showier upper face. It's worth asking to see both sides before buying, since the colour contrast is part of what distinguishes it from similar-looking species in the same group. There's no recorded sale price for this species on the site yet, so market value here is genuinely undocumented rather than just low-confidence.
