Where it comes from
Unlike the philodendron hybrids here, this one has a described species behind it and a range on record. Kew accepts Alocasia micholitziana Sander, published in The Gardeners’ Chronicle in 1912, and gives its native range as the Philippines, on Luzon — one island, which is a good deal more precise than the “Southeast Asia” the hobby tends to repeat. Kew lists no synonymssynonymA botanical name that is no longer the accepted one for a plant, usually because the same species was described twice. Old books and plant labels are full of them.Glossary.1 It grows in montanemontaneOf the cool, humid forest belt on a mountainside, above the lowland tropics.

Naming and description
micholitziana honours Wilhelm Micholitz, the collector who worked for the Sander nursery that published the species — which is why the species name and the publisher’s name go together.4 The fuller account, came a year later in Curtis’s Botanical Magazine.4
The plain plant is worth describing first: deep matt green, so dark it reads as black in poor light, with a texture closer to velvet than to leaf and bright white main veins running out to each lobe. It is smaller and more upright than its reputation suggests — about half a metre, carrying four to seven leaves at a time.1

Fun facts
- The velvet is structure, not pigment. The upper skin of a velvet leaf is made of domed, lens-shaped cells that focus incoming light down into the leaf instead of bouncing it back, which is what makes the surface look matt and deep and the veins look lit. That was measured in rainforest shade plants including a velvet-leaf anthurium, and it only reads as velvet when the leaf is dark to begin with.67 Water left sitting on the leaf tends to leave marks; why is not something I could find a source for.

An alocasia already runs a demanding plant on a handful of leaves at a time, and cream tissue photosynthesises little.

Either way, the plant that looks dead in November is usually fine underground — see the Alocasia care defaults and the general plant care page for what to do and, mostly, what not to.
- It is toxic and can hurt. All parts carry calcium oxalatecalcium oxalateNeedle-shaped crystals carried through the tissue of most aroids. They are the whole of the toxicity to cats, dogs and children: painful rather than poisonous.Glossary crystals: painful if eaten, and an irritant to skin and eyes.312
Care
Plant care- Light
- Bright indirect, and more of it than most people give them. They will not tolerate direct midday sun, but too little light produces weak petioles that cannot hold the leaves up.
- Water
- Water once the top few centimetres have dried through the growing season, and cut back sharply in dormancy — overwatering a resting plant is the main route to rot. Never waterlogged, never bone dry.
- Humidity
- Medium to high. Dry air browns the leaves and, more reliably than anything else, brings spider mites.
- Temperature
- 64-84 °F (18-29 °C) in growth, and not below about 61 °F (16 °C) while growing. Winter floor 50 °F (10 °C): below that, or in cooler and drier conditions generally, they drop leaves and rest, which is normal rather than fatal.
- Substrate
- Airy but moisture-retentive — bark and perlite with enough coir or sphagnum that it does not dry out in a day.
- Fertilizer
- A balanced feed at half strength every third watering through spring and summer. Nothing at all once growth stops.
- Propagation
- Offsets and the small tubers that form on the rhizome, separated at repotting. They root in damp sphagnum in a closed container.
- Dormancy
- Expected in a cool, dark winter — though a plant kept warm and bright may stay evergreen. It drops leaves and rests on the rhizome. Keep the mix barely damp, stop feeding, and do not repot; most losses happen when a resting plant is treated as a sick one.
- Common problems
-
- Sudden leaf loss in autumn is usually dormancy, not death — check the rhizome before discarding anything
- Spider mites are the defining pest of this genus; inspect leaf undersides weekly in dry air
- Drooping petioles that do not recover after watering usually mean rot below the soil
- Guttation — water beading at the leaf edge — is normal and not a symptom
- Every part carries calcium oxalate crystals: painful if eaten, and an irritant to skin and eyes
