You bought an Alocasia (a·luh·kay·zhuh) for your home; you have been looking at its foliage and wondering what it looks like.

Then you suddenly remember “Elephant Ears.” That is this plant’s common name.

Alocasia has beautiful foliage, but the flower, or shall I call it inflorescence, is not ‘eye-pleasing’ to look at.

Alocasia flowers consist of a spadix which is surrounded by a bright-colored spathe. The flowers usually bloom around summer and spring.

It must be hard to decide whether or not to let your plant flower and what risks and benefits are included in the process. Without any further ado, let’s jump right in.

Do Alocasia Flower Indoors?

Some plants need to be close to or in their natural habitat to flower, while some can flower even in an indoor setting. Well, you are lucky when it comes to Alocasia.

Although Alocasia has a higher chance of blooming in its natural habitat, it can bloom indoors if the conditions are right.

That means that you will have to emulate the plant’s natural habitat to have any chance to make the plant bloom.

It is rare for the Alocasia plant to produce flowers. You need to keep certain things in mind to make your plant flower. We will discuss that later.

If you witness blooming in Alocasia, it basically means that the plant is happy with the conditions you have provided it with.

Whether to keep or remove the blooms is entirely your decision to make. Some believe that the flowers will hinder the growth of the leaves, which are the center of attraction in Alocasia.

Flowers tend to take up the nutrients directed for the foliage.

Although the exact size is not specified, an Alocasia needs to be at least eight weeks old and must have a considerate size to flower.

Alocasia Flower Overview

Let’s look at the basic overview of the Alocasia flower.

StructureInflorescence with a rod-like spadix and a colorful spathe that surrounds the spadix.
Spadix contains cluster of small flowers.

Alocasia has unisexsual flowers. The male part lies at the top of the spadix, and the female part lies hidden in the floral chamber.

You don’t need to give much attention to the Alocasia flowers. They bloom, flourish and die off on their own after some time.

How to Pollinate the Allocasia Flower?

Pollinization is a process of transferring pollen from another to stigma to induce fertilization.

Alocasia will not self-pollinate due to its imperfect flowers. Female flowers grow on the upper portion of the spadix, while male flowers grow on the lower.

Male flowers normally produce pollen before female flowers bloom and are available for pollination. However, you can pollinate Alocasia flowers manually.

Alocasia can also fertilize by this process. Let’s look at the necessary steps.

  • Get a sterilized knife and a small paintbrush.
  • You can collect pollens a day after when the inflorescence first opens. However, it can depend on the environmental conditions as well.
  • Gently hold the spathe and cut a small portion at the base of the inflorescence to reveal the pistils.

  • Grab a dry brush and rub gently in the moist pistils and dip the brush in the pollen you want to use.
  • We then dab the brush on the exposed pistils to place as much pollen as possible.
  • Remember not to cut the entire spathe away to offer protection to the developing berries.

How to Make the Alocasia Plant Flower?

People with an Alocasia in their home don’t usually think about making the plant flower. Alocasia is one of the plants that is grown for its foliage.

But I get it; you are up for the challenge. You want to figure out the knowwhats of Alocasia flowering.

Look below for the conditions you need to keep in mind to make your plant flower.

  • The foremost and first thing you need to do is to check whether your plant is free of stress or not. Stressed Alocasia does not tend to flower.
  • Check the roots for root rot or root-bound if your plant seems stressed. Do the required preparations, choose a pot one size bigger than the current pot, and repot the plant.

  • Fertilizer with a high amount of phosphorus is suitable for making aroids flower. You can go for a water-soluble Monopotassium Phosphate (MKP) Fertilizer.
  • Water the plant according to its need. Wait for the top few inches of soil to dry out and thoroughly water the plant with distilled water.
  • Being a tropical plant, Alocasias prefer highly humid conditions (50-60%). Keep the humidity in check using a humidifier and a moisture meter.
  • You can also group houseplants to make a humidity-sharing environment.

You must know by now that you should check the plant thoroughly for the signs of pests and diseases. Or, the beautiful Alocasia foliage will be ruined.

  • Provide your Alocasia with a bright but indirect light to let it go in a ‘full bloom’ mood.
  • Soil also plays a significant role in making the plant flower. Mix a part of perlite/sand, a part of the soil, and the same quantity of peat moss.
  • Keep the temperature between 65°F to 85°F to let your Alocasia grow happily and produce flowers.

What Should you do with Alocasia Plant Flowers?

The beautiful leaves and the foliage of Alocasia has you in its charms already. But now you witness its ‘not-so-pretty’ flower.

Although the bloom is a sign that the plant is doing well, you would still want to cut it.

I can give you two reasons why you should discard the flowers altogether.

  • The term ‘flower’ is usually associated with’ beauty.’ But trust me, Alocasia blooms contradict that.
  • Blooms of Alocasia suck up the nutrients intended for the foliage. So, the leaves are usually smaller if a flower blooms.

The first reason alone is enough to make you want to remove the flower of Alocasia.

But wait! You cannot randomly remove the flower from the plant. There is a process and procedures you need to follow.

Look below for the steps to follow for removing the flower.

  • Choose the early morning hours for the cutting process. All night’s rest will help the plant wake up fresh and energetic.
  • Sterilize knives/shears properly and wear proper gardening gloves.
  • Grab the bloom at the base and identify the stalk connecting it to the plant.
  • Gently cut the stalk. You can also deadhead the flower to give your plant a better appearance.
  • Or, you can grab the bloom at the base and pull it out with your bare hands.
  • Follow the above process very carefully and do not hurt the neighboring leaves and stems.
