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 scalprum Morphology
About Alocasia scalprum
Alocasia scalprum is a species native to the humid wet tropical forests of the Philippines, specifically Samar. This compact, self-heading Alocasia grows terrestrially in warm, humid understory conditions, typically reaching a medium size. Its leaves are narrow sagittate to lanceolate, with a metallic dark green surface and a deeply quilted, heavily bullate texture. The prominent veins and slightly purplish undersides give it an 'armor-like' appearance suited to its shaded native habitat.

Samar, Philippines
Propagation Guide
How to Propagate Alocasia scalprum
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 scalprum 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 Most Peculiar Quilt from Samar
Right, a proper cuppa ready, let's discuss *Alocasia scalprum*. This rather intriguing chap hails from Samar in the humid, wet tropical forests of the Philippines, a fascinating discovery indeed. Alistair Hay, bless him, formally described it only recently. It’s a wonderfully compact, self-heading species, perfectly adapted to its shaded understory habitat. Those leaves! Narrowly sagittate to lanceolate, with a metallic dark green surface that’s almost absurdly quilted and bullate. Gives it a splendid 'armor-like' quality, doesn’t it? The prominent veins and purplish undersides are a fine touch. Keeps one quite chuffed in these drafty British glasshouses, a stark reminder of warmer climes. A worthwhile addition, though careful with the humidity; propogating them can be a bit of a faff.
