Before You Buy
Species-specific things to check when evaluating a listing
- Check the corm is firm — a soft or shrunken corm indicates dehydration or rot and is very difficult to recover
- Verify there is at least one established leaf; avoid bare corms from unknown sellers unless you have experience germinating alocasia corms
- Spider mites are the most common pest: inspect leaf undersides for fine webbing or stippling, especially in dry indoor environments
- Alocasias can enter dormancy when stressed by shipping — a plant arriving with no leaves but a firm corm is not necessarily dead
Alocasia chaii Morphology
About Alocasia chaii
Alocasia chaii is a compact, self-heading aroid species naturally found in the wet tropical forests of Borneo, specifically Sarawak. It thrives terrestrially or lithophytically on rainforest floors, rocky slopes, or limestone outcrops, preferring deep humus, high humidity, and filtered light. This species forms a basal corm from which erect, slightly arching petioles, deep maroon to purple in color, emerge. Its distinctive leaves are thick, heavily bullate, and strongly textured, ranging from narrowly ovate to lanceolate with pronounced central and lateral veins. The upper surface is a glossy dark green, contrasting with the deep maroon to purple undersides, giving the plant a rugged, sculptural, and jewel-like appearance.
Native Range
Sarawak, Malaysian Borneo
Propagation Guide
How to Propagate Alocasia chaii
Wait for the mother plant to produce corms or pups before dividing. Larger, well-established plants produce offsets most readily. Alocasias do not propagate reliably from stem cuttings.
Care Guide
Alocasia chaii Care Guide & Growing Conditions
Well-draining loamy mix: 40% potting compost, 30% perlite, 20% orchid bark, 10% worm castings. Alocasias need moisture retention unlike most aroids but still require good drainage.
Keep evenly moist during the growing season — never waterlogged, never bone dry. Check soil every 3–4 days in summer. Reduce significantly in winter when growth slows.
60–80%. Lower humidity causes brown leaf edges; very low humidity combined with dry compost will trigger dormancy.
Balanced fertiliser at half strength every 2 weeks during spring and summer. Stop feeding in winter.
Every 12–18 months in spring. Alocasias like being slightly snug in their pots — don't overpot.
Common Problems
Leaves yellowing and dropping
Overwatering, cold temperatures, or natural dormancy
Reduce watering; ensure temperatures stay above 16°C; dormancy is normal in winter
Brown leaf edges
Low humidity or irregular watering
Increase humidity and maintain consistent watering routine
Spider mites
Most common pest; thrive in hot, dry conditions
Mist regularly; treat with neem oil or insecticidal soap; increase humidity
A Rather Compact Character
Right then, *Alocasia chaii*. Not a cuppa, though one often yearns for a proper brew whilst slogging through the Bornean undergrowth! This splendidly compact, self-heading aroid, formally described by the venerable P.C. Boyce, is a true Bornean marvel from Sarawak. We found it thriving either terrestrially or lithophytically on limestone outcrops, preferring deep humus and filtered light – rather sensible of it. Its deep maroon petioles support leaves that are, quite frankly, a marvel: thick, heavily bullate, and a glossy dark green above, contrasting with the deep maroon undersides. A rugged, jewel-like thing. Almost makes one forget the perpetual drizzle back home.
