An Alocasia plant is a genus of flowering plants in the arum family, Araceae. They are native to Asia and northeastern Australia. This means they thrive in tropical and subtropical climate. Alocasia plants are commonly known as elephant ears because of their large, glossy, heart-shaped leaves.

What are Alocasia plants?

Some species are popular ornamental plants in cultivation, grown for their striking foliage. They enjoy a humid environment, well-drained soil and bright, indirect light. They are sensitive to cold temperatures and do not tolerate frost or even cold air coming in from an open window. Looking at the stem, you will find that this plant species is propagated by division or by rooting stem cuttings.

In accordance with their native areas, these great indoor plants prefer warm, humid conditions and bright, indirect light to thrive indoors. They should be kept in a room with temperatures between 15-32°C (60-90°F) and away from drafts or cold windows.

How often should I water my plant?

Since the species prefers high humidity, misting the leaves or placing a humidifier nearby can help. They also like to be kept consistently moist, but not waterlogged, so it’s important to not let the soil dry out completely, whilst also making sure to not over-water. The soil should be well-draining, as alocasias are sensitive to root rot. They also benefit from regular fertilization during the growing season, with a balanced liquid fertilizer. As with most indoor plants, I do not recommend using fertilizer outside of the growing season, as this may disturb the plant’s natural growth cycle.

Is an Alocasia toxic?

It is generally recommended to keep Alocasia plants away from children and pets, as many species of this genus contain calcium oxalate crystals, which can be toxic to cats and dogs if ingested. The symptoms of poisoning include drooling, difficulty swallowing, oral irritation, vomiting and in severe cases difficulty breathing and tremors.

It’s worth noting that not all Alocasia species contain calcium oxalate crystals.

So, if you have pets in your home, it is best to keep your plant in a location that is out of reach of your pets. Or, if possible, consider growing a different type of houseplant that does not pose a risk to your pets. Personally, I keep my Alocasia in my bedroom, where my two cats aren’t allowed to go. It’s worth noting that not all species contain calcium oxalate crystals, so it’s best to check with the specific plant species you have.

Can you touch Alocasia plants?

Alocasia plants are generally safe to touch, but some individuals may experience skin irritation or an allergic reaction to the plant. As I mentioned, sap of some Alocasia species contains calcium oxalate crystals, which can cause skin irritation, itching, or a rash. Additionally, some people may be allergic to the plant and can experience symptoms such as itching, redness or rash.

I recommend washing your hands after handling the plant, just to be sure. In case you notice any symptoms of skin irritation or an allergic reaction, stop handling the plant and seek medical attention if necessary.

Different types of Alocasia

There are many types of Alocasia plants. Each of them has its own unique characteristics. Some of the most popular varieties include:

  • Alocasia Amazonica, also known as the Amazon Elephant’s Ear, which has large, green leaves with a wavy edge.
  • Alocasia Polly, also known as the African Mask, which has glossy, dark green leaves shaped like an arrowhead.
  • Alocasia Odora, which has large, fragrant leaves that are green with a white underside.
  • Alocasia Zebrina, which has large, green leaves with white or yellow stripes.

These are only a few examples of the many types of Alocasia plants that are available. Each one has its own unique look and care requirements, so it’s important to research and choose the right one for your specific needs and growing conditions.
