Welcome to our guide to the black velvet alocasia reginula. It grows in the wild in Malaysia, and makes great house plants as long as you meet it’s care needs…

Light Needs

Alocasia reginula will grow well from medium to bright indirect sunlight. They do well under grow lights to be honest, with a constant environment. I would put them in an east or west facing window.

How Often to Water An Alocasia Reginula

Water when the top 30% of soil is dry, check it once a week with your finger.

Tip: when it comes to watering keep them moist but not soaking wet, tip out excess water after watering so they don’t get a soggy bottom! You don’t want them to dry out either.


Use a balanced feed once a month in summer to encourage growth. If the plant is young, use a really well diluted feed ad gradually increase the dose each time you feed, this way you can avoid fertilizer bun on the leaves.


A well draining, loose potting mix will be ideal. I use a mix of orchid bark, perlite and normal compost. For more on which soil to buy or how to make your own see our guide: Alocasia Soil.

When To Repot

You can repot them when they become really root bound. Do not stress though as these plants are ok with some crowding, you just don’t want to get them really crowded which can stop water running through the pot and cause root rot.

Alocasia Reginula Humidity

60% humidity. They like to be in a humid environment, so at least consider a pebble tray for these if your home is not at that.

Tip: Keep them humid, at least 60% in the day and they’ll be ok with a bit less at night. You can buy a humidity meter (affiliate link) to keep an eye on maximum and minimum levels.


18-25ºC (64-77ºF). Which is luckily inside the normal household range. Don’t let it get too cold at night, 10ºC (50ºF) is a good minimum temperature.

Alocasia Reginula Propagation

The best and easiest way to propagate it is is to divide them at the base. You’ll need to find a plant which already has started to produce smaller plant (or ‘pups’) at the base.

The stems grow from tubers just under the soil. The roots grow from out of the tubers too. These tubers grow under the soil and spread out as the plant grows, and new smaller plants then grow from them.

To split them off, you need to take your plant out of it’s pot and get rid of as much soil as possible from the roots and tuber. Then you want to get the smaller plant that is growing on the side and remove it from the rest of the plant BUT make sure you take a section of tuber as well as some roots with it. Then you’ll have a brand new plant to pot up.

Pot them both up in separate pots, give them a good watering and you’re done. Easy!

Is It Toxic to Cats?

It is toxic to cats and dogs if ingested, so seek vets advice immediately if you think your pet has eaten any.
