Alocasia 'Maharani'

Breeding history and wild origins

Alocasia ‘Maharani’ is a hybrid of Alocasia reginula × Alocasia melo, attributed to Peter Boyce at Malesiana Tropicals around 2009.

Alocasia melo grows on ultramafic rock and thin streamside soil in lowland Sabah rainforest. Alocasia reginula is probably Bornean, but its wild setting is unknown. The melo parent connects ‘Maharani’ with warm rainforest, moving water nearby and very shallow mineral ground.

Growing corm-forming aroids indoors

• Light: Keep Alocasia ‘Maharani’ in bright shade or filtered light. Avoid hot direct sun; weak light slows growth and weakens the petioles.
• Watering: Water as the surface begins to dry. Small root balls dry quickly, but corms should never sit in soggy mix or standing water.
• Humidity and airflow: Aim for high humidity. A dry room often requires a humidifier or cabinet; add gentle airflow and dry wet leaves promptly.
• Substrate and repotting: Let a new plant settle in its nursery pot. Later, choose a pot only slightly larger than the root system.
• Feeding: Use a complete fertiliser at a low dose sparingly while growth is active. Feed less often when growth or available light decreases.
• Leaf care: Use a soft brush or barely damp cloth without pressing into the texture. Check recessed veins for pests.

Troubleshooting Alocasia 'Maharani': compact textured leaves and recessed veins

Fine pale dots collect beneath the blade

Angle light beneath the metallic or deeply textured blade and inspect vein recesses with magnification. Tilt the metallic or heavily textured blade under bright light and inspect the lower veins for repeated stippling, cast skins and fine webbing. A removable surface deposit differs from fixed pinprick fading that repeats across the blade and is accompanied by webbing. Keep the textured plant apart, clean only if the surface tolerates it and treat the lower veins and compact crown with a spider-mite product. The spider-mite guide

Several compact textured leaves lose firmness

Loss of one oldest leaf can be ordinary turnover when the corm and newer growth remain firm. When several textured leaves lose firmness, compare pot weight with moisture below the surface and the condition of the roots and corm. Lift the pot and check the lower root zone rather than judging from the textured leaves. Water firm dry roots thoroughly, but inspect softness in damp mix before adding water.

Map where the damage begins, before repeating a treatment

Trace the position of the first mark on Alocasia 'Maharani': exposed face, sheltered surface, margin, growing point or base. Its location across the compact textured leaves and recessed veins helps separate exposure, pest feeding, repeated drying and loss of root function. Use the next healthy leaf or offset to confirm recovery; scars and dead patches on older growth will remain visible. Repeat treatment at the labelled interval only if mites, insects or fresh feeding damage are still present.

Alocasia ‘Maharani’ is toxic to pets

• Alocasia ‘Maharani’ is toxic to cats and dogs.
• Chewing releases insoluble calcium oxalate crystals, which can cause immediate mouth pain, drooling and difficulty swallowing.
• Contact a veterinarian promptly after suspected chewing, especially if swelling or breathing problems occur.

Alocasia: a name altered from Colocasia

Alocasia was coined by altering Colocasia, the name of a related aroid genus.
