What’s Unique About Alocasia Polly?

Ironically, although two of the common names for the Alocasia Polly plant are Amazonian Elephant’s Ear and African Mask Plant, its roots are in another continent altogether.

The parents of Alocasia Polly plants are native to China, Southeast Asia, and the Philippines, and this cultivar was developed by a Florida breeder in the 1950s.

The large leaves with their unique pattern are the main attraction of this tropical houseplant. 

At the same time, its small size means that even in homes with limited space, you can find room for growing Alocasia Polly.

It can also help clear your air of harmful chemicals such as formaldehyde.

Alocasia Polly Care

Alocasia Polly’s family of plants originates in the rainforests of Southeast Asia. 

Because of this, good Alocasia Polly plant care entails supplying this tropical plant with growing conditions as close to the rainforest as is practical.

Alocasia amazonica care essentially involves bright, indirect light, consistently moist soil, and a warm, humid environment.


In the rainforest, Alocasias grow on the forest floor under the tree canopy. While the tropical sun is hot and bright, the trees filter it for the understory plants.

In your home, Alocasia Polly light requirements are for bright but indirect light, or between 10,000 to 20,000 lux.

Alocasia amazonica light needs can be met by placing it directly in an east or north window where it will receive the less intense morning light.

If all you have is a south or west exposure, find a spot in the room out of the full sun, which can burn the leaves or bleach out their color.


In the rainforest, Alocasias thrive in damp soil which is never saturated. Your Alocasia Polly watering routine needs to maintain the same consistent moistness.

Water Alocasia amazonica whenever the top inch of the soil is dry. This will be at least once a week during the growing season. Just gently moisten the top layer. 

Never let your Alocasia Polly sit in water. The roots need air, and saturated soil will not let it get to them.

Alocasia Polly watering needs are less in its winter dormant phase. You can let the soil dry out to about halfway down before watering.


The best Alocasia Polly temperature range is 64 to 77ºF (18 to 25ºC). 

Luckily, most modern heated homes are kept at an appropriate temperature for Alocasia amazonica.

Alocasia Polly has limited temperature tolerance below that range. If temperatures fall below 64ºF (18ºC), it will go into dormancy and growth will stop.

Even being in a draft or too close to an air conditioning vent can have an adverse effect on your Alocasia Polly. Also, keep it away from windows when it’s really cold outside. 

Finally, Alocasia Polly has no frost hardiness. Even a brief exposure to 32ºF (0ºC) can cause irreparable damage.


Alocasia Polly humidity requirements are high, because that is what it’s like in the rainforests where Alocasias grow wild.

The ideal humidity for Alocasia amazonica is between 60 and 75%. That humidity level is of course not advisable for your home, but there are ways to create a humid microclimate for your Alocasia Polly.

Probably the best way to raise the humidity in the air surrounding your Alocasia Polly is to use a small humidifier. 

Grouping all of your tropical plants together will allow all of them to benefit at once from the extra moisture.

You could also regularly mist your Alocasia Polly’s leaves, or place its pot atop a pebble tray filled with water.


Alocasia Polly soil has to both hold enough water to stay consistently moist, while at the same time drain excess water and let the roots breathe.

The pH level for Alocasia amazonica is 5.5 to 6.5, or mildly acidic.

You can buy a commercial aroid mix to use as the soil for Alocasia amazonica. African violet soil will also meet all of Alocasia Polly’s needs.

However, you can also make your own soil mix.

Standard indoor potting soil can be mixed with equal parts of perlite and peat moss for a well-draining soil that will retain sufficient moisture. 


You should use a fertilizer for Alocasia amazonica to encourage strong, healthy growth of its large leaves. 

Alocasia Polly fertilizer should have a fertilizer ratio of 10-10-10. 

Liquid houseplant fertilizers are the easiest way to feed your Alocasia Polly. Dilute it to half the recommended strength to avoid burning the roots.

Apply the liquid fertilizer evenly around the soil surface. You should do this right after you’ve watered the plant to ensure that the liquid is absorbed into the moist soil.

You should feed your Alocasia Polly once a month during spring and summer, but not during its dormant period in the fall and winter.

Potting & Repotting 

While Alocasia Polly does not mind being a little root-bound, Alocasia Polly repotting should be done every 2 or 3 years.

Repotting Alocasia amazonica gives you an opportunity to divide the roots to propagate more plants. 

You should also refresh the potting soil at the same time.

Only move up one pot size, or at most 2 inches across, when selecting a new pot for your Alocasia Polly.

It’s a good idea to use a glazed clay or plastic pot, as a pot with porous materials will lead to the soil drying out too quickly. Just make sure it’s got good drainage holes.


Alocasia Polly pruning is rarely necessary.

You cannot limit the height of your Alocasia Polly by pruning at the top, as new leaves are borne on stems that grow from the base. 

It’s not advisable to remove healthy stems and leaves.

The only time you should be cutting Alocasia amazonica is to remove dead or damaged leaves.

Not only will these leaves mar the appearance of your Alocasia Polly, but they can also harbor pests and disease.

Don’t just cut off the leaf; take out the entire stem down to the soil level. 

To trim your Alocasia Polly, always use sharp, sterilized knives or scissors. 


Alocasia Polly propagation is usually done by root division. Stem cuttings will not produce new plants.

However, it’s really very easy to propagate Alocasia amazonica when you are repotting your plant every 2 years or so.

Start by pulling the root ball out of the pot, and shake off as much of the soil as you can.

You should see a tangle of individual corms twisted together. Gently tug them apart, cutting only when necessary. 

Each plantlet that has both roots and leaves can be potted up separately, either to expand your own tropical garden or to share with others.

Common Problems of Alocasia Polly

Alocasia Polly can be a little fussy to grow, but most Alocasia Polly problems can be avoided by providing it with the proper growing conditions.

If problems with Alocasia amazonica do develop, most of them can easily be resolved.

The leaves of your Alocasia Polly act as a good early warning system for any potential issues.


There are very few Alocasia Polly pests. In fact, the only bugs that you are likely to find on your Alocasia amazonica are spider mites.

Spider mites suck the sap out of the leaves of Alocasia Polly, leaving a series of small white or yellow dots that will eventually turn brown. 

It’s hard to actually detect spider mites, as they are very small, but you may also find their sticky webs in more advanced infestations.

Take your Alocasia Polly into the shower and spray down all surfaces. This should remove the bugs.

Keep them away for good by wiping down the leaves once a month with a neem oil solution.


Most Alocasia Polly diseases are encouraged by the moist soil and high humidity that this plant needs to thrive.

Since you can’t keep Alocasia amazonica without the moisture, you need to keep an eye out for any signs of disease.

Root rot is the most common disease affecting Alocasia Polly. If the leaves start drooping and turning yellow, and the stems become soft, pull the root ball out of its pot.

Cut away any roots that are turning black, as well as the affected leaves and stems. Repot in fresh soil.

Rust is a fungal disease that causes orange to brown spots on the leaves. It’s caused by wet conditions on the foliage. Cut out all affected leaves, and do not mist the leaves in future.

Growing Problems 

Other growing problems aren’t caused by pests or disease, but rather by poor growing conditions resulting in a sick plant. 

Just giving it a more nurturing environment can restore it to health.

If the edges of your Alocasia Polly’s leaves are turning brown and crisp, and the plant is drooping, it needs more water. Increase your watering frequency.

If the leaves are curling up, it needs higher humidity and/or less bright light.

If your Alocasia Polly’s leaves are dying off, there’s a good chance that it’s not in a warm enough spot and is going dormant. Move it to a warmer spot out of drafts.

Toxicity of Alocasia Polly

Alocasia amazonica is toxic to humans and animals, so care should be taken when growing this tropical plant.

Its toxicity is caused by calcium oxalate, which is found in all parts of the plant.

Calcium oxalate has tiny sharp crystals that can pierce sensitive tissues and cause potentially life-threatening reactions, especially in children and pets.

For Humans 

Alocasia Polly is toxic to humans.

While adults are unlikely to try eating this ornamental plant, young children may get curious and try a bite.

If they just ingest a bit, the most likely reaction is some localized pain in their lips and mouth. Clean away the plant material and give them a popsicle to soothe the pain.

However, if they have a swollen tongue, or difficulty breathing, take them to the emergency room immediately.

If you have sensitive skin, you may develop a rash if exposed to the sap. Rinse it off and use an antihistamine cream to soothe symptoms. 

For Pets 

Pets can have a severe and possibly life-threatening reaction to ingesting Alocasia Polly foliage or stems.

If your cat, dog, or rabbit starts drooling excessively, vomiting, or wheezing, or has diarrhea, you should take it to the veterinarian immediately. 

It’s a good idea to prevent a situation like this from arising by finding a spot for your Alocasia Polly that pets and children can’t reach. 

Since a mature Alocasia Polly may only grow to 2 feet tall, it can easily be kept on a shelf several feet above floor level. 

If you keep it in your bathroom because of the higher humidity levels, keeping the door closed will solve the problem, too.

Alocasia Polly Appearance

Between its striking, large leaves and elegant growth habit, the Alocasia Polly appearance will stand out wherever it is used.

Whether it’s a solitary specimen plant, or included in a larger indoor garden, its evergreen good looks will always get a reaction. 

While it may never flower for you, the leaves alone are enough to make it worth growing.


The foliage of Alocasia Polly is its most outstanding characteristic. 

An Alocasia Polly leaf can grow up to a foot long, and is shaped like an arrowhead. The edges are ruffled, and the whole leaf has a rippled appearance.

The dark green, glossy leaves have thick contrasting veins in shades of silvery white. They have a leathery texture.

Alocasia Polly is evergreen, so while some older leaves may die off during its winter dormancy, most foliage remains intact.

Because the leaves last a long time, they should be wiped down once a month to remove any dust that has accumulated.


It is very unlikely that you will see an Alocasia Polly flowering when it is grown indoors in a pot.

Blooming usually only occurs on Alocasia Polly plants grown outdoors in a tropical zone. The bloom time is in summer.

The flowers are small and insignificant, with a green spathe wrapped around a white spadix. 

Many growers choose to cut out flower stalks before they bloom. Flowering and setting seeds uses energy that the Alocasia Polly plant could otherwise direct towards its big, beautiful leaves.

For the most part, trying to get your Alocasia Polly to bloom is not worth the effort.

Size and Growth 

Alocasia Polly was bred to be a compact version of Alocasia × amazonica, so the size of Alocasia Polly will stay on the small side.

It will grow to a full height and spread of 12 to 24 inches. It has a fast growth rate, producing 1 or 2 new leaves each month during spring and summer.

An Alocasia Polly plant has an average lifespan of about 5 years. However, since it can be propagated by divisions you can always have fresh young plants growing.

Alocasia Polly naturally forms a graceful shape, with leaves arching out on its stiff, upright stems.

Alocasia Polly Fragrance

There is no Alocasia Polly fragrance. 

The rare Alocasia amazonica flower has no scent, and the foliage is also unscented.

This can be an advantage if you are growing Alocasia Polly in a small space like a studio apartment and are sensitive to fragrances.

As well, in many public settings such as nursing homes, medical offices, and schools, fragrant plants are not permitted because of some people’s sensitivity. Alocasia Polly is an ideal plant to use in those places.

If you do enjoy scented plants, you can include some such as camellias in your indoor garden to perfume the air while also enjoying the look of Alocasia Polly.

Suggested Uses for Alocasia Polly

If you live in a tropical region, you can grow Alocasia Polly outdoors year-round. Plant it in rich, moist soil in a shady spot, and you may even see flowers develop.

Indoors, the compact size of Alocasia Polly lends itself to a variety of uses. It’s small enough to tuck into a corner of a kitchen counter or on a shelf in a bathroom.

In your bedroom, you can appreciate its beauty by day, and sleep in a less contaminated atmosphere by night as it filters the air.

Even in temperate zones, Alocasia Polly can become a part of your outdoors garden in hot summer months.
