Why is Monstera Thai Constellation So Expensive?

So, what makes the Thai constellation so pricey? One reason is, of course, consumer demand and popularity. It is a newer plant that everyone wants. This has the potential to raise prices and sometimes resellers do that themselves as well.

Another significant reason is that this stunning yellow-to-white variegated Monstera Deliciosa was created in a lab. It was specifically created in a tissue culture laboratory in Thailand. This is the reason why it has ‘Thai’ in its name.

Unlike most plant origins, which can be traced back to multiple locations, this plant can only be traced to one location on the planet. As a result, the Thai Constellation is extremely rare and can be difficult to obtain.

And thanks to its origins, the Thai constellation also cannot be grown by seeds. This further reduces the plants’ capacity for mass production, making them potentially harder to find which drives up the price even more.

Thai Constellation Monstera Care

A popular plant among lovers of indoor plants is the Thai Constellation Monstera, also known as the Variegated Monstera or Monstera Deliciosa Thai Constellation.

This magnificent plant stands out in any indoor garden thanks to its distinctive variegation, which includes bright white or cream splotches and splashes on its dark green leaves. A rare cultivar of monstera called the Thai Constellation Monstera was first found in Thailand in the late 1990s.

It is a cross between the well-known aroid plants Monstera Deliciosa and Epipremnum Pinnatum. The genetic mutation that caused the variegation makes it much harder to reproduce, which raises its rarity and value.

Proper care is essential for the health and vitality of your Thai Constellation Monstera. By providing the right conditions, you can ensure that this tropical beauty thrives in your home. Let’s dive into the key aspects of care:


Thai Constellation Monstera plants prefer bright, indirect light. Place them near a north or east-facing window, where they can receive ample sunlight without being exposed to harsh rays. Avoid placing them in direct sunlight, as this can scorch their delicate leaves.

If you notice your plant leaning towards the light source, simply rotate it every few weeks to encourage even growth.

Monstera Deliciosa, its parent plant, is native to the tropics, where it receives lots of bright light filtered through the canopies. The Thai Constellation Monstera therefore needs the same amount of bright indirect lighting, if not more. Low light conditions should be avoided at all costs.

If your Thai Constellation is not receiving enough light, you will observe discolored leaves, slower growth, and leaves that do not split properly.

By mimicking this natural lighting condition in your home, you are creating an environment that closely resembles its native habitat, allowing your plant to thrive and display its stunning variegation.

Drainage should be the top priority when choosing a soil for your Thai Constellation Monstera. Make sure that the soil is moist but never soggy or mushy.

A good option is a mix of high-quality soil, sphagnum moss, and perlite. This combination provides the right balance of nutrients and aeration.

In their natural habitat, these plants grow in the moist forest floor, where the soil is rich in organic matter. This type of soil composition allows for proper drainage while retaining enough moisture for the plant’s roots to absorb.

When choosing a potting mix, it’s important to select one that mimics these natural conditions. The peat moss provides moisture retention, while perlite ensures good drainage. The well-balanced potting soil supplies the necessary nutrients for the plant’s growth and overall health.

By using the right soil mix, you are recreating the ideal growing conditions for your Thai Constellation Monstera, giving it a solid foundation for optimal growth.


When it comes to watering your Thai Constellation Monstera, it’s important to find the right balance. Overwatering can lead to root rot, while underwatering can cause its leaves to curl and turn brown.

Ensure the top inch of soil is dry before watering and then thoroughly drench the soil until water drains out of the bottom of the pot. Repeat this process when the top inch of soil feels dry to the touch.

The plants are more prone to root rot than the parent Monstera Deliciosa. So proper watering is critical. Before watering again, make sure the top several inches of soil are dry, or use a moisture meter.

In their natural habitat, these plants receive regular rainfall, followed by periods of dryness. This natural cycle allows the roots to absorb water and then dry out slightly before the next watering. By replicating this watering pattern, you are providing your Thai Constellation Monstera with the ideal conditions for healthy growth.

Plus, using filtered water or allowing tap water to sit for 24 hours before watering your plant can help remove any chlorine or chemicals that can be harmful. This extra step ensures that your plant receives clean and safe water, just like it would in its native environment.

Temperature and Humidity

The Thai Constellation Monstera thrives in warm and humid conditions, mimicking its natural tropical habitat. Maintaining a temperature range between 65°F and 85°F (18°C and 29°C) is ideal.

In their native habitat, these plants grow in warm and humid regions, where temperatures remain consistently high throughout the year. The warm temperatures provide the necessary energy for growth, while the high humidity levels keep the leaves lush and vibrant.

To increase humidity levels, you can place a tray filled with pebbles and water beneath the plant or use a humidifier. Grouping plants together can also create a microclimate that helps retain moisture. These methods mimic the humid conditions of the rainforest, ensuring that your Thai Constellation Monstera feels right at home.

By maintaining the appropriate temperature and humidity levels, you are creating an environment that closely resembles its natural habitat, allowing your plant to thrive and showcase its stunning foliage.


Regular feeding is essential for the vigorous growth of your Thai Constellation Monstera. During the growing season (spring and summer), use a balanced liquid fertilizer diluted to half strength every four weeks. This will provide the necessary nutrients for healthy foliage and vibrant variegation.

In their natural habitat, these plants receive a constant supply of nutrients from decaying organic matter on the forest floor. To replicate this in a home setting, regular fertilization is necessary. The balanced liquid fertilizer provides a wide range of essential nutrients that support the plant’s overall health and promote lush growth.

During the dormant season (fall and winter), reduce the frequency of fertilization to once every two months or cease fertilizing altogether. This allows the plant to rest and conserve energy during its natural growth cycle.

By providing the right nutrients at the right time, you are ensuring that your Thai Constellation Monstera receives the essential elements it needs to thrive and display its stunning variegation.

Thai Constellation Monstera Variegations and Fenestrations

One of the most captivating features of the Thai Constellation Monstera is its stunning variegated leaves. The cream-colored patterns on the lush green foliage create a mesmerizing effect, making it a true statement plant.

In addition to the variegations, this Monstera variety also develops fenestrations, which are Swiss cheese-like holes in the leaves. These fenestrations give the plant its unique charm and add another layer of visual interest.

Thai Constellation Monstera Fenestrations

To encourage the growth of fenestrated leaves, provide your Thai Constellation Monstera with bright, indirect light and maintain proper humidity levels.

When it comes to variegated plants, the Thai Constellation Monstera is truly a standout. Its leaves are adorned with stunning cream-colored patterns that contrast beautifully against the deep green background.

These variegations can vary in intensity, with some leaves displaying bold, contrasting patterns, while others have more subtle markings. Regardless of the variation, the variegations give the plant a striking appearance that is sure to catch the eye of any plant enthusiast.

But the visual appeal of the Thai Constellation Monstera doesn’t stop at its variegated leaves. This plant also develops fenestrations, which are a unique characteristic among Monstera varieties.

These fenestrations, often referred to as “Swiss cheese holes,” create a fascinating and intricate pattern on the leaves. They not only add visual interest but also serve a purpose in the plant’s natural habitat.

These fenestrations are believed to have evolved as a way for the plant to adapt to its environment. In their native tropical rainforests, where light is often limited, the fenestrations allow sunlight to penetrate through the leaves and reach the lower parts of the plant.

This adaptation ensures that the Thai Constellation Monstera receives sufficient light for photosynthesis, even in the dense forest understory.

If you want to encourage the growth of fenestrated leaves on your Thai Constellation Monstera, it is important to provide it with the right conditions. Bright, indirect light is essential for the development of these unique features. Placing your plant near a window where it can receive filtered sunlight or using artificial grow lights can help create the ideal lighting conditions.

As your Thai Constellation Monstera matures and grows, you may notice that the variegations and fenestrations become more pronounced. This is a natural part of the plant’s growth process, and with proper care, you can enjoy the ever-increasing beauty of its leaves.

How to Propagate Thai Constellation Monstera

Propagating the Thai Constellation Monstera is an exciting way to expand your plant collection or share this beauty with friends. Thankfully, this plant is relatively easy to propagate through stem cuttings.

Thai Constellation Monstera is a stunning variegated plant with unique patterns on its leaves. It is a popular choice among plant enthusiasts due to its striking appearance. If you want to propagate this plant and create more of these beautiful specimens, follow these simple steps:

  1. Select a healthy stem with at least two nodes.
  2. When selecting a stem for propagation, it’s important to choose a healthy one. Look for stems that are free from any signs of disease or damage. The stem should have at least two nodes, which are the points where leaves emerge.Using a clean, sharp knife or shears, make a clean cut just below a node.
  3. Before making the cut, make sure your knife or shears are clean and sharp. A clean cut will promote faster and healthier root development. Cut the stem just below a node, ensuring that you have a clean and straight cut. Remove any leaves from the lower portion of the stem, leaving only a few at the top.
  4. To encourage root growth, it’s essential to remove any leaves from the lower part of the stem. By doing so, you direct the plant’s energy towards root development rather than leaf maintenance. Leave a few leaves at the top to support photosynthesis. Place the cutting in a jar of water or a well-draining potting mix.
  5. There are two popular methods for propagating Thai Constellation Monstera: water propagation and soil propagation. If you choose water propagation, place the cutting in a jar of water, ensuring that the cut end is submerged. If you prefer soil propagation, use a well-draining potting mix to plant the cutting. Ensure the cut end is submerged in water or planted in soil and provide indirect light.
  6. Proper light conditions are crucial for successful propagation. Place the jar of water or potted cutting in an area with indirect light. Direct sunlight can be too harsh for the delicate roots, so it’s best to avoid placing them in direct sunlight. Monitor the moisture levels, keeping the soil damp but not soggy.
  7. It’s important to maintain the right moisture levels during the propagation process. If you’re using water propagation, regularly check the water level and make sure the cut end remains submerged. For soil propagation, keep the soil damp but not overly wet. Overwatering can lead to root rot and hinder the propagation process. After a few weeks, roots will begin to develop, signaling successful propagation.

Patience is key during the propagation process. After a few weeks, you will start to see tiny roots emerging from the cut end of the stem. This is a positive sign that your propagation efforts have been successful. It’s important to continue providing the right care and monitoring the plant’s progress.

Once the roots are established, you can transplant the cutting into its own pot and continue to care for it as you would any mature Thai Constellation Monstera.

Remember to provide the plant with adequate light, water, and nutrients to ensure its healthy growth. With proper care, your propagated Thai Constellation Monstera will thrive and become a beautiful addition to your plant collection.

Potting and Repotting Thai Constellation Monstera

Proper potting and repotting are crucial for the growth and overall well-being of your Thai Constellation Monstera. These steps will guide you through the process, ensuring that your plant thrives in its new home.

First and foremost, it is important to choose a pot that is one size larger than the current one. This allows room for the plant to grow and expand its root system. A pot that is too small can restrict root growth and lead to stunted development.

When selecting a pot, make sure it has drainage holes. These holes are essential for preventing waterlogging, which can cause root rot and other detrimental conditions. Proper drainage ensures that excess water can escape, maintaining a healthy balance of moisture in the soil.

Before potting your Thai Constellation Monstera, fill the bottom of the new pot with fresh, well-draining soil. This will provide a solid foundation for the plant and promote healthy root growth. Well-draining soil allows excess water to flow through, preventing water from pooling around the roots.

Now it’s time to carefully remove the plant from its current pot. Gently tap the sides of the pot to loosen the soil and roots. Be cautious not to damage the delicate roots during this process. If the plant is tightly rooted, you can use a clean, sharp knife or garden shears to carefully loosen the roots without causing harm.

Once the plant is free from its old pot, place it in the new pot. Position it in the center, ensuring that it sits at the same depth as it did in the previous pot. Add additional soil around the sides, gently pressing it down to secure the plant in place. The soil should be firm enough to support the plant but not compacted, allowing for proper aeration and root growth.

After potting, it’s important to give your Thai Constellation Monstera a thorough watering. This will help settle the soil and provide a good start for the newly potted plant. Water until you see water flowing out of the drainage holes, indicating that the soil is adequately moistened.

Remember, repotting should be done every 1-2 years or when the roots become crowded. This gives the plant the necessary space to grow and ensures optimal nutrient absorption. Keep an eye on the root system of your Thai Constellation Monstera and be proactive in providing it with a suitable pot and fresh soil when needed.

Common Pests and Plant Diseases for Thai Constellation Monstera

While the Thai Constellation Monstera is a relatively hardy plant, it is not immune to pests and diseases. Here are a few common issues you may encounter:

  • Spider Mites: These tiny pests can be identified by the fine webbing they create on the leaves. Use a natural insecticidal soap or neem oil spray to control them.
