Alocasia 'Metalhead'

Alocasia 'Metalhead'

Alocasia 'Metalhead' is a cultivated Alocasia with dark glossy leaves and deep purple undersides. The plant grows upright on firm petioles, so the colour contrast is visible as leaves tilt above the pot.

The dark upper surface and coloured reverse become clearer as new leaves harden. Fresh growth can look softer at first, then firms into a thicker Alocasia blade with a smoother sheen.

Dark foliage traits of Alocasia 'Metalhead'

• Growth habit: Upright cultivated Alocasia with firm petioles.
• Leaf colour: Dark green glossy upper surfaces.
• Leaf underside: Purple reverse that shows when leaves tilt or rise above the pot.
• Texture: Smooth, substantial Alocasia blades as leaves mature.
• Container behaviour: Needs enough space for upright stems and enough drainage for fleshy roots.
• Plant type: Cultivated Alocasia with dark foliage and coloured leaf reverses.

Purple reverses and upright petioles

Alocasia 'Metalhead' grows from a fleshy Alocasia base and produces leaves on separate petioles. Its dark leaf surface can show dust quickly, and cleaning the leaves also makes pest checks easier.

The root system needs air as much as moisture. A loose, mineral-rich aroid mix keeps the root zone open while still holding enough water for the leaves.

Care routine for Alocasia 'Metalhead'

• Light: Bright indirect light keeps the plant upright and compact. Avoid harsh direct sun on the dark glossy blades.
• Watering: Water thoroughly, then let the top layer begin to dry before watering again.
• Substrate: Use a chunky mix with bark, pumice, perlite or similar mineral structure so roots do not sit in stagnant moisture.
• Temperature: Keep warm and stable. Cold wet substrate can damage Alocasia roots quickly.
• Humidity: Higher humidity helps new leaves open without sticking, especially on larger leaves.
• Leaf checks: Inspect the purple undersides often, as pests are easier to miss there.
• Feeding: Use a diluted fertiliser while the plant is actively producing leaves.
• Potting: Repot when the root ball fills the container or the plant becomes top-heavy.

Alocasia 'Metalhead' problem cues

• Spider mites: Fine webbing or pale speckling on the underside is an early warning sign.
• Yellow leaves: Usually linked to wet roots, cool conditions or natural shedding of an older leaf.
• Brown margins: Irregular watering, dry air or damaged roots can mark the edges.
• Weak petioles: Low light can stretch stems and make the plant lean.
• Leaf marks: Cold damage or rough handling can leave dark patches on glossy foliage.

Safety for Alocasia 'Metalhead'

Alocasia 'Metalhead' is toxic if chewed. It contains irritating calcium oxalate crystals, so keep it away from pets and children and avoid contact with sap from cut or damaged tissue.

Raised on firm petioles, Alocasia 'Metalhead' shows dark glossy upper surfaces and purple leaf reverses as the foliage matures.
