Englerarum montanum albo-variegata

Where Alocasia ‘Gageana Variegata’ comes from

Alocasia ‘Gageana Variegata’ belongs to Alocasia odora ‘California’, a compact form of Alocasia odora from Myanmar. Its precise origin in Myanmar is unknown. Give it bright indirect light in a warm room. During active growth, water regularly and use a loose mix that lets excess water drain.

Keeping Alocasia gageana ‘Variegata’ healthy

• Light: Give it very bright indirect light, with gentle early sun after acclimation. A sheer curtain can soften intense rays before they reach the cream areas.
• Water: Soak the pot when the upper layer feels partly dry. The vigorous roots prefer regular moisture and complete drainage, with a longer pause during slower winter growth.
• Humidity and temperature: Average to moderately high humidity suits this plant in a warm room. Air moving between the many stems helps the centre dry after watering; keep the pot away from cold floors and draughts.
• Potting mix: Use chunky bark or coco chips with coir and pumice. A sturdy pot only slightly larger than the roots supports the broad plant and limits excess wet mix.
• Feeding: Feed at low to moderate strength while fresh leaves are appearing. If a mineral crust forms, water generously once to wash it through the pot.
• Division: Wait until a basal shoot has roots of its own before separating it. Its future leaves may arrange the cream, mint and green areas differently from the parent plant.

Common problems with Alocasia gageana ‘Variegata’

• Pale areas develop dry edges: Move the plant away from strong sun or hot airflow, keep watering steady and rinse the mix if salts have collected. Trim the edge after it dries completely.
• New leaves become smaller: Look first at seasonal light, root space, room temperature and feeding. Repot once the roots have filled the container.
• Several leaves yellow around a soft base: Inspect the rhizome and roots, cut away decay and replant the healthy part in fresh, loose aroid mix. Choose a pot that fits the roots left after trimming.
• Silver streaks and black specks appear: Thrips often gather inside rolled leaves and among the crowded shoots. Check every shoot, move the pot away from other plants and treat every shoot and leaf. Keep watching the rolled leaves and repeat treatment if fresh marks appear.
• Fine webbing or pale speckles appear: Rinse both sides of every leaf to remove spider mites, treat the whole plant and inspect neighbouring plants. Check again and repeat treatment if webbing or pale speckles return.

Englerarum montanum albo-variegata 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 is it called Englerarum montanum?

Englerarum commemorates botanist Adolf Engler. Montanum means “of the mountains” or “mountain-growing”.

Lars Nauheimer and Peter Charles Boyce established the genus Englerarum in 2013 in Plant Systematics and Evolution, volume 300, page 713.

William Roxburgh first described it as Arum montanum in 1832 in Flora Indica, 1832 edition, volume 3, page 497. Peter Charles Boyce, Khant Zaw Hein, and Alistair Hay later placed it in Englerarum as Englerarum montanum in 2022 in Aroideana, volume 45, issue 3, page 145.
