We hyperlink to distributors that can assist you discover related merchandise. In the event you purchase from one in every of our hyperlinks, we might earn a fee.
What’s somewhat further watering and creating a moist oasis right here within the dry air of my residence when such magnificence and drama are the outcomes?
Described with numerous widespread names together with African masks, large taro, kris plant, and elephant ear, Alocasia species boast massive, stunning leaves that will be at residence within the tropics, which is the place they originated.
And that’s what makes them somewhat more durable to develop and take care of than the typical pot of philodendron or spiderwort. They want situations that mimic the areas the place they’re native.
A couple of of their rising necessities embody humidity of no less than 50 p.c, residence temperatures of 60°F or larger, and loads of vivid, oblique mild.
If creating that setting indoors feels like one thing you’d be keen to do, gained’t you let me introduce you to a few of the dramatic varieties on this genus?
When you’re extra acquainted with what these vegetation have to supply, I’ll additionally share tips about accommodating their particular rising wants.

What Is Alocasia?
Vegetation of the Alocasia genus are native to Southeast Asia, southern China, and japanese components of Australia.
They show their tropical origins with showy leaves in quite a lot of patterns and textures, and a passion for vivid, oblique mild and many humidity, just like what they’d obtain within the understory of the rainforest.
The genus accommodates 97 acknowledged species, although most of these accessible to informal indoor gardeners are sometimes called “jewel” varieties – compact vegetation that develop to a few ft tall in a house setting.
Alocasia is beloved by houseplant fans for its spectacular foliage – vivid or darkish inexperienced leaves that may strategy a foot lengthy, with angular shapes and heavy veins of both inexperienced or white.
Some varieties have silvery foliage with deep inexperienced leaf edges and veins, and others function variegated leaves.
An endearing a part of their development behavior is the way in which the clumps of leaves develop vertically as a substitute of sending out horizontal runners, like many vegetation that originated within the tropics do.
When grown outside, these vegetation bloom within the spring sending up an inflorescence consisting of a central stalk generally known as a spadix surrounded by a spathe, just like that of a peace lily. They hardly ever flower indoors, nevertheless.
Like mates you’ve had for many years, or your loved one canine, alocasia goes by many alternative nicknames, together with African masks, kris plant, and elephant ear.
It shares that final widespread identify with a variety of different ornamentals, together with members of the Colocasia and Xanthosoma genera.
Alocasia, Colocasia, and Xanthosoma belong to the aroid or Araceae household, and have related development habits.
Xanthosoma can be tropical, however it’s native to South and Central America.
Alocasias may be cultivated as out of doors perennials in USDA Hardiness Zones 8b to 11, and so they can attain six to 12 ft when grown in supreme situations in landscapes or gardens, relying on the species.
On this information, we’ll concentrate on rising Alocasia elephant ears indoors, or as potted out of doors specimens that overwinter inside within the chilly months.
This genus gives drama in a potted plant.
Only a few of the probabilities embody A. infernalis aka “black magic,” with shimmery purple-black leaves; A. odorata var. variegata, with heart-shaped leaves flecked with totally different patterns; A. x amazonica, a hybrid with shiny, arrow-shaped leaves and intense veins; and A. sanderiana, aka the kris plant or Sander’s alocasia, that includes darkish inexperienced, shiny leaves with huge white margins and leaf veins.
One which I lengthy so as to add to my assortment is A. macrorrhizos ‘Stingray,’ a large taro cultivar. It has striped or mottled markings on its upright stems and ribbed leaves that function a tail on the ends that’s harking back to a stingray.
It grows three to 5 ft tall – no aquarium required, in contrast to its namesake.
A. zebrina additionally options stems with darkish inexperienced or brown stripes, and arrow-shaped leaves.
Rising any of those varieties might contain a couple of extra cautions and further steps than you’re used to seeing if you search tips on rising houseplants which are easier to take care of.
I do know this firsthand and might solely say – it’s price that further work!
Nurturing this tropical plant in my own residence has required me to arrange an space with extra constant mild, and better humidity than my typical succulents require, for instance.
However my reward has been a dramatic kris plant to take pleasure in indoors. And it’s a stunner, with boisterous, outsized leaves and a tropical vibe you simply can’t get from a tiny pot containing a extra modest specimen.
If caring for this type of houseplant feels like a little bit of a stretch for you, welcome to the membership. Learn on for ideas that may make the method of rising and caring for elephant ears extra manageable.
A Observe of Warning:
The insoluble calcium oxalate alocasia accommodates makes the leaves and stems poisonous to people, canines, cats, and horses.
As well as, it could actually trigger pores and skin irritation, so it’s advisable to put on gloves when dealing with these vegetation.
To be secure, solely develop alocasia the place curious pets and youngsters can’t attain it.
Propagation
As a result of the leaves sprout from a central rhizome, you gained’t have the ability to propagate Alocasia by rooting stem or leaf cuttings.
It’s doable to propagate the tiny corms that develop on the base of the rhizome, however I wouldn’t advocate this technique.
It’s unreliable and tedious, taking many months and never essentially yielding any new vegetation.
From Divisions
Fortunately, there are solely a few steps concerned in propagating alocasia from divisions.
In case you have a good friend with a kris plant or an elephant ear of your personal that’s spreading by way of rhizomes, rising new specimens from divisions is the way in which to go.
This chore is greatest accomplished when the plant is popping out of its winter dormancy.
However when you can see roots rising from the drainage holes within the plant’s container, you possibly can go forward and repot, and seize any offshoots which have two or extra leaves on the identical time.
To separate offshoots, ease all the plant from the pot with one hand, holding it over a tabletop coated with newspaper or an empty, clear sink.
Utilizing your free hand, tease out any offshoots which are already separate from the mother or father or that may be disentangled readily. You should definitely maintain the rhizome and roots intact with every clump.
For clumps which are entangled with the roots of the mother or father plant, use a pointy, clear paring knife to chop them away from the principle rhizome. Be certain to maintain the roots of every clump linked to the crown.
Plan to pot the severed or separated offshoots immediately. Learn on for extra particular instructions.
Transplanting
Earlier than you buy a plant from a neighborhood nursery or retailer, make sure that to choose up one which has a wholesome shade.
Keep away from any which have discolored leaves, which might point out a pest downside or that it’s been rising in substandard situations.
Whereas it’s a pure a part of getting older for Alocasia to drop a couple of leaves annually, a number of dry, predominantly brown stems or foliage are certain indicators of a plant that’s on its means out.
Additionally, test the drainage holes on the backside of the pot to verify the roots don’t have an off odor. In the event that they’re slimy and brown or odor a bit like a full diaper, go on that one. It might have already got a case of root rot, which is deadly.
In the event you’ve bought an alocasia on-line, be sure you schedule the supply for a time if you’re at residence so you possibly can instantly unpack the specimen and get it into a perfect setting.
Most on-line suppliers will embody instructions for caring for the plant upon arrival, together with whether or not it ought to instantly be repotted or given water or not.
This course of will fluctuate a bit relying on how the grower packs the alocasia and the way lengthy it takes to succeed in you.
A wholesome specimen can normally keep in its grower’s pot for a couple of months. Alocasia is content material in comfortable quarters.
In the event you discover loads of offshoots or the soil is drying out rapidly, it could be time to put the bought plant in a brand new pot.
Whether or not you’re potting up offshoots you’ve separated your self or transplanting or repotting a bought specimen, the tactic is basically the identical.
You should definitely select a fast-draining soilless combine formulated for indoor vegetation.
One sensible choice is Miracle-Gro Indoor Potting Combine, which is accessible from Dwelling Depot in 16-quart luggage.

You’ll additionally want a pot with drainage holes and a saucer to catch extra water because it drains out. The container ought to be about two inches wider on all sides than the transplant.

When it’s time, you could word that roots are rising out of the drainage holes or that the soil now not absorbs water as readily.
You should definitely solely transfer to a pot that’s a dimension bigger than the earlier one, about an inch or two wider on all sides.
And be sure you gently knock free the previous potting combine from the roots in the course of the transition. Alocasia appreciates a soil refresh each two to 3 years.
