Alocasia Flowers: 5 Common Questions Answered (with photos)

Some of the links in this post may be affiliate links.

Have you been curious to learn more about Alocasia flowers, and what it means when you see them? Technically, they would be considered an Alocasia inflorescence, and I’ll explain later in this concise, informative post. Keep reading to learn all about Alocasia flowers and see the answers to the most common questions that people typically have concerning blooming Alocasias.

ALL ABOUT THE ALOCASIA FLOWER

1. WHAT DOES AN ALOCASIA FLOWER LOOK LIKE?

Technically, it is actually an inflorescence that you see on your Alocasia. Like all plants in the aroid (Araceae) plant family, Alocasias have a distinct inflorescence and they will all look pretty similar to each other.

In the illustrated photo below, the central, narrow structure in the middle is called the spadix, and the wider, green structure behind it is the spathe, which is technically a modified leaf. Below these two is an enlarged growth called the floral chamber.

In Alocasias, the female flowers are tiny and are hidden in the floral chamber, while the male flowers are on the upper part of the spadix. So while the majority of people call the spadix+spathe structure a flower, it is technically called an inflorescence.

The color, size and shape of the inflorescence will all vary a bit depending on the species of Alocasia, but they will all look fairly similar.

It is important to understand the floral structure if you want to experiment with pollinating Alocasia.

2. IS IT RARE FOR ALOCASIA TO FLOWER INDOORS?

Contrary to what you may have read in many posts online, it is NOT rare that they flower indoors.

The word rare has been used very loosely when it comes to plants, and it is simply not true that they rarely flower indoors.

Although many plants ARE shy bloomers indoors, Alocasia really isn’t one of them.

I have witnessed many Alocasia plants bloom indoors, as well have received many messages from my excited readers when they have sent me photos of their Alocasia inflorescences, asking what they are.

Alocasias will bloom when they are happy, and also when they are stressed (and you should know by looking at your plant if it is stressed or not!). If your plant is blooming, it is not necessarily an indication that your plant is in tip top shape.

3. WHAT TO DO WHEN ALOCASIA FLOWERS?

You can do one of two things:

  1. Leave it and enjoy it (although they’re really not that interesting and we grow Alocasias for their foliage and not the flowers.
  2. Cut off the entire inflorescence.

4. SHOULD I LET MY ALOCASIA FLOWER?

I would recommend always cutting off your Alocasia inflorescences as soon as you spot them.

The reason is that your plant will expend energy sustaining that growth, and most of us would rather redirect the plant’s energy into foliage growth instead. It’s really that simple.

5. WHERE TO CUT ALOCASIA FLOWER?

Like I’m showing you in the photo below, take a pair of sharp, sterilized pruners and cut as low as you can on the inflorescence stalk.

Take a look at all the ones I cut off below all from the same plant and in different stages of development.

At a bare minimum, to practice good hygiene, cut off the inflorescences after they are spent and don’t let them accumulate on your plant. It is best if you can cut them off as soon as you notice them though.

My Alocasia Regal Shield is flowering. I was excited until you said it flowers when stressed. I have had it about 3 years. The bottom leaves are browning and dying but the plant still looks healthy. Although I have seen a few mealybugs on her leaves. I have been fighting them to no avail. How do I get rid of those darn pests for good without tossing the plant?

Healthy plants will flower too. I would not worry about that! I have a post on mealybugs. Check it out and follow the process. You really have to stick with it and be consistent. Here it is, and good luck! https://www.ohiotropics.com/2023/11/14/how-to-treat-mealy-bugs-on-plants/

My Alocasia amazonica has flowered for the first time. I left it and now it seems to be forming a seed pod. I have read your advice and other people's feedback which I've found very helpful. Do you have any advice for what would happen if I left it to form the seed pod? I'm just curious. Any chance it will develop true seeds which could be germinated? The leaves still seem happy and aren't suffering as a result of leaving the flower to develop.

Hi Naomi! I've never grown these from seed, but if you want to experiment with that, you certainly can try. If you don't intend on attempting to grow the seeds, I would recommend cutting the seed pod off so the plant can focus its energy on growing more leaves instead.

At first I thought there was a new leaf comming, but it got round and looked different. I though it might be a flower and just found that out. The plant only has 3 leaves and 2 strange sort of stems coming from the bottom of the plant. People told me they were new plants and now I get a flower as well. This plant surprises and spoiles me !! I will leave the flower when it comes out and when it will wear off I will cut it. So I enjoy this rare moment. There was also a little bulb at the bottom with a tiny green tip, but I think that one did not made it.

They are definitely fun plants to watch and care for. Enjoy! :-)

Actually you don’t want to cut the flowers off. You are disrupting the flower cycle and it only takes energy from the plant. Pro botanists say leave them.

Thanks for the comment. I've never personally seen any negative repercussions though from doing this for years.

My Alocasias have only put out one single infloresence in 29 years, though they get huge, beautiful and healthy. From the article, I should consider that fortunate? They have the habit of pulling themselves out of the ground over time, requiring them to be planted deeper again. But since they die off over the winter, it is not much work to do.

Hi Larry! It sounds like your plants are big and healthy and you're happy with them, so that's all that matters :-)
