How to Grow Alocasia — A Complete Care Guide (and the New Varieties Worth Knowing)

Alocasias have a reputation for being divas. They're really not — they're just honest. They tell you exactly when something is off, and once you understand what they're asking for, they're some of the most rewarding plants you can grow. This guide walks you through the whole thing: the exciting new varieties landing in collections right now, and everything you need to keep them thriving.

Why everyone's talking about Alocasia again

Alocasias — the "elephant ears" — have always been admired for their dramatic, sculptural foliage. What's changed is access. Tissue culture has quietly transformed the genus, taking plants that were once nearly impossible to find and making them genuinely collectable. Varieties that sold for silly money a couple of years ago are now within reach, and breeders are crossing the most striking parents to produce new compact hybrids almost every season.

There are over 80 known species in the wild, and the indoor scene now spans everything from giant statement plants to tiny textured jewels that sit happily on a desk. If you've only ever met a supermarket "Polly," there's a whole world waiting.

The newer varieties worth knowing

The jewel Alocasias

This is where a lot of the current excitement sits. Jewel Alocasias stay compact, with thick, textured, almost metallic leaves — more like polished stone than foliage. Black Velvet is the gateway: deep, matte-black leaves with silver-white veins. From there, growers fall hard for the metallic types — glossy purple leaves with pink or red venation and dramatic dark undersides. These were only formally described in the last several years, so they still feel genuinely new, and they reward anyone who can give them a little extra humidity.

The dragon family

Named for their scaled, reptilian leaf texture. Silver Dragon shows a metallic-silver finish that shifts as light moves across it, with inky purple-black veins for depth. Dragon Scale leans greener with the same incredible embossed texture, and Pink Dragon brings rosy stems into the mix. These are some of the most photogenic plants you'll ever own — the texture does all the work.

The new discovery: Jacklyn

One of the most distinctive Alocasias to enter cultivation recently. Jacklyn (botanically Alocasia tandurusa) was only properly introduced to growers a few years ago out of Indonesia, and the name tandurusa comes from local words meaning "deer antlers" — which makes sense the moment you see it. The leaves are deeply lobed and almost antler-shaped, with bold dark veins that branch dramatically across translucent green. It starts compact and desk-friendly, then matures into a real floor-standing statement plant. Not the easiest first Alocasia, but a brilliant next step.

The variegated and hybrid wave

The biggest shift of all. Variegated forms of old favourites — the velvet-leaf green types and the dragon-scale lines splashed with cream — used to be unicorns. Tissue culture is steadily making them more available. Alongside that, breeders are crossing jewel-type parents with dragon-scale parents to produce new compact hybrids with colour and texture you simply couldn't get from a single species. If you like being early to something, this is the corner of the genus to watch.

Getting the basics right

Light

Bright, indirect light is the sweet spot. Alocasias evolved on the shaded floor of tropical forests, so harsh direct sun will scorch and bleach the leaves — keep them off hot, unfiltered windowsills. An east-facing window or a bright spot a metre or two back from a brighter window is ideal. They'll survive in dimmer rooms, but growth slows and the plant slowly declines, so don't tuck them into a dark corner and expect magic.

Water — and the trap that kills most of them

Overwatering is the number one Alocasia killer, full stop. The goal is lightly moist, never soggy. Let the top few centimetres of mix dry out, then water thoroughly and let it drain completely. Never leave the pot sitting in a saucer of water. If you're unsure, wait a day — these plants recover from being a touch too dry far more easily than from sitting wet.

Humidity

This is where Alocasias quietly ask for more than the average houseplant. Aim for 60% or higher, and the jewel types appreciate even more. Grouping plants together, a pebble tray, or a small humidifier all help. Higher humidity also keeps the leaf edges from going crispy and makes the whole plant noticeably more robust.

Temperature

They love warmth — roughly 18–27°C is the comfort zone. Once things drop below about 15°C they start to sulk, and a cold snap can trigger an early dormancy (more on that below). Through a Hunter Valley winter, keep them away from cold draughts and unheated rooms, and they'll coast through fine.

The mix — a well-draining blend

If you take one thing from this guide, make it this: Alocasias hate a dense, water-holding mix. Their roots want air. A standard potting soil packed around the roots is a fast track to rot. Instead, build a well-draining aroid mix — think a base potting medium loosened generously with perlite, bark, coco and a little pumice, aiming for a slightly acidic, free-draining blend. You want water to flow through and air to reach the roots between drinks.

Feeding

Alocasias are reasonably hungry during the warmer growing months. A balanced fertiliser at a gentle, diluted rate through spring and summer keeps the new leaves coming. Ease right off as things cool down and the plant slows — feeding a dormant plant just builds up salts in the mix that do more harm than good.

Dormancy — the part that scares everyone

Here's the thing nobody warns new growers about: your Alocasia might drop every single leaf over autumn or winter, and that's often completely normal. It's not dead. Alocasias grow from a corm (a little underground storage bulb), and in cooler, darker months they can go dormant and pull all their energy back into it.

If this happens, do not throw the pot out. Gently check that the corm is still firm. Reduce watering to a bare trickle so it doesn't rot, keep it somewhere warm, and wait. When spring returns and warmth and light come back, it'll push out fresh leaves like nothing happened. More Alocasias are killed by panic in winter than by anything else.

Quick troubleshooting

• Yellowing leaves: usually overwatering. Check the mix isn't staying wet, and that the pot drains freely.
• Drooping: often thirst or a humidity drop — but check it's not actually waterlogged first, since both look similar.
• Crispy brown edges: air's too dry. Lift the humidity.
• Fine webbing or stippled, faded leaves: spider mites, which love dry indoor air. Inspect the undersides, treat early, and raise humidity to discourage them.
• Mushy base or rotten smell: root rot from staying wet. Unpot, cut away the damage, and repot into fresh well-draining mix — or move it to semi-hydro to reset.

One safety note: like most aroids, Alocasias contain calcium oxalate and are toxic to pets and kids if chewed. Keep them up and out of reach.

Making more of them

Alocasias multiply through their corms and offsets rather than from cuttings. As a plant matures it produces little corms around the base; you can pot these up into a moist, airy mix, or root them in a humid container with a touch of water until they sprout. Spring and summer are the time to do it, when the plant is actively growing and most willing to bounce back. It's slow, but there's nothing quite like growing a whole new jewel Alocasia from a corm the size of a pea.

Where to start

If this is your first one, begin with a velvet type and learn the watering rhythm. If you've kept Alocasias alive before, this is a brilliant moment to step up — the jewels, the dragons, Jacklyn and the new variegated hybrids are more available than they've ever been.

And if you need anything to get growing — a well-draining aroid mix, semi-hydro mediums, the right nutrients, or a humidity setup — head to the shop, where you'll find all you need.
