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 longiloba 'Dragon's Tooth'
Alocasia longiloba 'Dragon's Tooth' has narrow longiloba leaves with pointed tips, defined basal lobes, and a dark surface cut by pale veins. The blade shape gives this Alocasia a sharp, tooth-like outline.
This Alocasia grows from a rhizomatous base and holds its blades on upright petioles. Filtered light, higher humidity during unfurling, and a breathable mix help the pointed leaves develop with fewer dry marks or creases.
Pointed leaves with pale vein contrast
- Leaf shape: Narrow sagittate leaves develop pointed tips and defined basal lobes.
- Leaf colour: Dark green upper surfaces contrast with pale to silvery veins.
- Undersides: Purple to burgundy tones may show beneath the blade when present on the plant.
- Growth base: A rhizomatous base anchors the upright petioles and needs good airflow around the roots.
- Texture: Thin, pointed leaf sections can mark quickly after sun scorch, dry air, or rough handling.
Rhizome, blades, and indoor growth
Alocasia longiloba is a wet-tropical species with sagittate to hastate leaf forms, pale venation, and often darker undersides. 'Dragon's Tooth' has a narrow, pointed, vein-marked blade shape.
The rhizomatous base makes watering and substrate structure important. A chunky mix keeps oxygen around the roots, while higher humidity helps new pointed leaves open with fewer creases or dry tears.
Care for Alocasia longiloba 'Dragon's Tooth'
- Light: Give bright filtered light. Direct sun can scorch the dark blade surface and pale veins.
- Watering: Keep the mix lightly moist, then water again once the upper part has begun to dry.
- Substrate: Use a chunky, oxygen-rich mix around the rhizome and roots.
- Humidity: Higher humidity helps pointed new leaves unfurl with less sticking, creasing, or edge damage.
- Temperature: Keep warm and steady. Cold wet substrate can damage the rhizome and trigger yellowing leaves.
- Positioning: Keep the leaves away from hard contact with walls or shelves, as narrow tips can bruise easily.
Marks on narrow Alocasia leaves
- Dry tips or torn edges: Low humidity, mechanical damage, or stuck new leaves can mark the pointed leaf sections.
- Brown vein areas: Direct sun or root stress can leave dry patches along pale veins and thin blade tissue.
- Yellowing lower leaves: Check for a pot that stays wet or a root zone exposed to cold.
- Soft rhizome area: Wet, compacted substrate can damage the base before the leaves show severe symptoms.
- Pests: Spider mites and thrips can scar the leaves and distort new growth. Inspect new spears and leaf undersides.
Safety
Alocasia longiloba 'Dragon's Tooth' is not pet-safe. Its tissues contain insoluble calcium oxalates that can irritate the mouth and digestive tract if chewed or swallowed.
Botanical background and origin
Alocasia longiloba is an accepted species in the Araceae family, first published by Miquel in 1856 in Flora van Nederlandsch Indie. The genus name Alocasia was formed in relation to Colocasia, a closely allied aroid genus, while the epithet “longiloba” means long-lobed and matches the extended lobes seen in longiloba-type leaves. The species ranges from southern China to western and central Malesia, where it grows in wet tropical habitats.
