Alocasia 'Maharani'

Where the parent species of Alocasia ‘Maharani’ grow naturally

One parent of Alocasia ‘Maharani’ is Alocasia melo, which grows beside fast streams in Sabah rainforest with its roots in thin soil over mineral-rich rock. The natural habitat of its other parent, Alocasia reginula, is unknown.

Alocasia ‘Maharani’: care essentials

• Light: Give ‘Maharani’ bright, filtered light. Strong direct sun can leave scorched or faded areas on its textured leaves.
• Temperature: Aim for 23–28°C.
• Humidity: Maintain approximately 65–80%.
• Watering: Wait until roughly the upper third to half of the substrate has dried, then wet the root ball evenly and allow drainage to finish fully.
• Substrate: Use a very open mix containing bark, perlite or pumice and a moisture-retaining organic component.
• Repotting: Choose a small, close-fitting container. Repot when the roots have filled most of the available space.
• Feeding: Use a light fertiliser dose during active growth.
• Propagation: Separate offsets or small corms after they have developed enough stored energy to establish independently.
• Handling safety: Before repotting or unpotting, disturbing the root ball, cutting, pruning, division or propagation, wear gloves and keep Alocasia sap away from skin and eyes. After handling, wash hands and clean tools.

What to check on Alocasia ‘Maharani’

• Rough quilted foliage or new blisters appear: The thick textured surface is normal. New translucent underside blisters that become corky support oedema; empty standing water, confirm drainage, reduce prolonged saturation and improve gentle airflow. Existing corking remains, so judge later growth.
• Leaf undersides shift from green towards red: Firm, even colour change as a leaf matures is healthy. If an area becomes soft or water-soaked, isolate the plant, keep foliage dry, stop splashes and mark the edge. If one severely affected leaf must be removed, wear gloves and keep sap away from skin and eyes before cutting it with a disinfected tool, then wash hands and clean the tool. Continued spread, recurrence or entry into a petiole or crown needs professional diagnosis before further cutting or chemical treatment.
• Brown margins develop: Check actual root moisture, direct light or heat, mineral crust, feeding history and cold. Water and drain only when genuinely dry; flush salts only with firm roots and free drainage, and move exposed foliage into bright filtered light.
• Yellowing continues in wet mix: Stop watering and empty standing water. If decline persists, wear gloves and keep sap away from skin and eyes before unpotting; after handling, wash hands and clean tools. Retain firm roots and base tissue, remove only directly confirmed dark, mushy, hollow, slimy or collapsing tissue with disinfected tools, and repot into fresh airy medium in a clean draining pot sized to the surviving roots. Seek professional diagnosis before cutting an unclear or soft crown.

Alocasia ‘Maharani’: toxic if chewed

• Pets: This Alocasia is toxic to cats and dogs. Keep the plant and any cut pieces where pets cannot chew them.
• Children and handling: Keep it out of reach of children. Sap from damaged tissue can irritate skin and eyes, so wash your hands after pruning and avoid touching your face.
• Why it irritates: Alocasia tissue contains insoluble calcium oxalate crystals. Chewing or contact with sensitive tissue can cause immediate local irritation.
• Possible symptoms: Mouth exposure can cause burning pain, drooling, swelling, nausea or vomiting, and difficulty swallowing.
• After exposure: For a pet, contact a veterinarian. For a person, remove any plant material from the mouth and rinse with water; seek medical or poison-control advice if symptoms are significant. Breathing difficulty or rapidly increasing swelling needs urgent medical attention.

Why the hybrid is called ‘Maharani’

Maharani is Hindi for “queen”. The name echoes one parent, Alocasia reginula, whose epithet means “little queen”.

Peter Boyce created the Alocasia reginula × Alocasia melo hybrid at Malesiana Tropicals around 2009.
