How to read these values
These care values are quick reference points for indoor growing. Use them as a guide, then adjust for pot size, substrate, temperature and how quickly the substrate dries.
For more detail, read the full product description or visit our Plant Care Guides.
- Light: level and approximate lux at leaf level.
- Watering: “% dry” shows how far the substrate should dry before watering again.
- Substrate: structure, drainage, moisture retention, base material and particle size.
- Temperature: “Ideal” shows the preferred range; “Avoid below” marks the cold-stress threshold.
- Humidity: target range; steady conditions usually matter more than exact numbers.
- Growth habit: how the plant grows, such as upright, climbing, trailing, clumping or rosette-forming.
- Support: whether a stake, pole or trellis is needed, optional or unnecessary.
- Growth speed: expected pace under suitable indoor conditions; use as a guide, not a promise.
- Max size indoors: realistic long-term indoor size under good conditions.
- Toxicity & safety: irritation, toxicity or physical hazards such as spines or bristles.
- Origin & habitat: native range, hybrid background or typical habitat where relevant.
- Outdoor growing: when a potted indoor plant can be placed outside and what outdoor protection it needs.
Alocasia scalprum
Alocasia scalprum is a small Philippine species from Samar, grown for narrow, blade-like leaves with a firm surface and a blue-green to grey-green mature finish. It is often known as Samar Lance, a name that fits both its origin and its long pointed leaf shape.
A small corm sits at the centre of the plant and gradually forms a compact cluster of narrow leaves. Mature blades are usually around 15–25 cm long and 2–5 cm wide, with short petioles and a slightly curved outline. New leaves emerge softer and greener, then harden into darker, firmer blades with clearer ribbing and a subtle metallic cast.
Samar origin and narrow blade growth
Alocasia scalprum comes from Samar in the Philippines. In cultivation, its small corm and narrow leaves respond best to warmth, steady moisture, an airy base and light feeding during active growth.
Its compact size suits a small warm pot where the corm can root firmly and new leaves can mature without stress. Older leaves naturally age as fresh growth forms.
Care for a small Alocasia scalprum corm
- Light: Give bright indirect light. Strong filtered light helps the leaves stay firm, narrow and well coloured.
- Watering: Water once the top part of the mix has dried. Even moisture followed by full drainage keeps the corm in better condition.
- Substrate: Use a fine-to-medium airy mix with bark, pumice or perlite, coco fibre and a small amount of moisture-retentive material. Air around the corm is essential.
- Temperature: Keep warm, especially around the pot. Cold roots slow growth and make wet substrate more risky.
- Humidity: Moderate to high humidity helps reduce dry tips and supports smooth new leaves.
- Feeding: Feed lightly during active growth. Small repeated doses are safer than heavy feeding.
Repotting around the corm
Repot Alocasia scalprum only when the pot is well rooted or the mix has lost structure. A close-fitting pot keeps moisture easier to judge around the small corm. Move up one small pot size and keep the corm firm, warm and slightly raised from the wettest part of the mix. After repotting, water carefully until new roots are active again.
Offsets and corm division
Propagation is by offsets or corm division. Wait until a young growth has its own roots before separating it. Very small corm pieces can rot quickly if kept too wet, so use a small airy pot, steady warmth and gentle humidity. New divisions usually grow slowly at first, then produce stronger narrow leaves once the root system settles.
Mineral mixes for scalprum
Alocasia scalprum can grow in mineral mixes when the texture is fine enough for a small root system but still open enough for air. A mix with pumice, perlite, small bark and a little water-retentive material gives the small roots moisture contact while keeping air around the corm. Semi-hydro is best for rooted, unstressed plants; keep the water level low and keep the corm above the wettest layer.
Narrow-leaf problems
- Yellow leaves: One older leaf can age naturally. Several yellow leaves together usually point to a root, temperature or watering problem.
- Dry tips: Dry air, salt build-up or uneven watering can mark the narrow blades.
- Drooping leaves: Sudden droop can follow dry roots, cold stress or a saturated lower pot.
- Soft base: Softness near the corm means the base has had too little oxygen or too much cold moisture.
- Pests: Thrips and mites can mark the backs of the narrow leaves and the folded new spear.
A solitary scalprum inflorescence
Mature plants can produce a solitary inflorescence with a green spathe and a spadix shorter than the spathe. Indoors, the narrow textured leaves are present far more often than flowers.
Handling narrow leaves safely
Alocasia scalprum contains irritating calcium oxalate crystals and is toxic if ingested. Keep it out of reach of pets and children, and wash your hands after handling cut tissue.
Scalprum name and Samar Lance
Alocasia scalprum A.Hay was published in 1999 and belongs to Araceae. The epithet scalprum comes from Latin for a cutting or scraping tool, matching the narrow pointed blades. The nickname Samar Lance reflects both its Samar origin and the lance-like leaf shape used in cultivation.
With steady warmth, filtered light and an airy base, Alocasia scalprum keeps the narrow, firm leaves behind the Samar Lance name.
