Alocasia sp. Sulawesi ‘Sabrina Narrow’

Background of Alocasia ‘Sabrina Narrow’

‘Sabrina’ is an Alocasia species from Sulawesi, Indonesia, and ‘Narrow’ is the name for this particularly slender form. Its exact natural habitat on Sulawesi is unknown. Indoors, give it bright indirect light, warmth and moderate to high humidity. Keep an open mix lightly moist and let excess water drain.

Everyday care for Alocasia sp. Sulawesi ‘Sabrina Narrow’

• Light: Grow the plant in bright, indirect light and filter strong midday sun. Turn the container periodically to encourage even development across its narrow, spreading foliage.
• Watering: Water when the substrate surface is just beginning to dry. Wet the mixture fully, empty the runoff and maintain light, consistent moisture around the rhizome and roots.
• Temperature: Keep the plant around 22–26°C during active growth. Protect the developing foliage from cold draughts and rapid temperature changes.
• Humidity: Aim for 60–80% relative humidity. A consistent level supports the opening of new leaves and reduces dry margins.
• Airflow: Provide gentle air movement where humidity remains high. Soft circulation around the foliage is preferable to forceful air from fans, heaters or cooling systems.
• Substrate: Select an airy mixture of peat-free compost or coir, fine bark and pumice or perlite. The fine-grade components distribute moisture evenly through the root zone.
• Feeding: Use a weak, complete liquid fertiliser during active growth. Reduce applications when leaf production pauses and resume once a new shoot becomes visible.
• Repotting: Move the plant into the next pot size once the rhizome and roots have filled the container. Choose a close-fitting pot, retain the original planting depth and repot during active growth when possible.
• Propagation: Divide rooted offsets from the parent plant or collect cormels during repotting. Start cormels at 25–30°C in lightly moist, airy substrate and pot them on once roots and a shoot are established.

Narrow leaves and signs of damage

• Narrow, wavy leaves: Narrow blades with gently undulating margins are part of this plant’s usual appearance. Leave firm, evenly coloured leaves in place.
• Twisted, silvered growth: Folded or twisted new leaves marked by silvered scratches and black specks may be damaged by thrips. Focus the inspection on leaves that are still opening, then isolate the plant and apply a product labelled for thrips. Repeat as directed on the label.
• Dry, curling margins: Dry, curling margins often reflect low humidity or uneven moisture. Raise humidity steadily and water once the upper layer has partly dried.
• Drooping in damp substrate: Yellowing, drooping foliage in a damp mix can signal root damage. Let excess moisture drain, examine the root system and transfer the plant to an airy mix after cutting away soft, dark tissue.

Alocasia sp. Sulawesi ‘Sabrina Narrow’ is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• Its leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, throat, skin and eyes.
• Chewing may cause burning pain, drooling, swelling, vomiting or difficulty swallowing. Contact a veterinarian or medical professional after exposure, especially if swelling or breathing problems occur.

Why Alocasia sp. Sulawesi has no species citation

Alocasia combines the Greek prefix a-, meaning “without” or “lacking”, with Colocasia, the name of a related aroid genus.

The formal botanical citation is Alocasia (Schott) G.Don. George Don established the genus at that rank in 1839 in Hortus Britannicus, edition 3, page 631.

The abbreviation sp. indicates an unidentified or not yet formally described species. ‘Sulawesi’ is a provisional locality label, not a published species epithet. Because no species name has been established, there is no species author, year or publication to cite.
