Anthurium clarinervium is a plant with a striking look that catches the eye. Its leaves are large and heart-shaped, showcasing vibrant green colors with interesting white veins that stand out.

The plant has a lush and velvety texture which you can feel when you touch the leaves. Flowers of the Anthurium clarinervium are less noticeable than the leaves but are still pretty, typically appearing as a small spike with a protective leaf-like part.

The stem is sturdy and supports the weight of the large leaves. When fully grown, the plant can be quite impressive in size, making it a statement piece in any space.

Leaf Size

The Anthurium clarinervium has large leaves. They grow big, about 15 to 25 centimeters long (6 to 10 inches). When you look at the plant, the leaves are often the first thing you notice.

They’re like big, green hearts. As the plant gets older, the leaves can get even bigger. Each new leaf might be a bit larger than the last.

A fully grown leaf will usually stay within the size range, but the exact size can vary. It depends on how much care and space the plant has.

Leaf Shape

The Anthurium clarinervium has heart-shaped leaves. Picture a heart you would draw or see on a Valentine card; that’s the kind of shape its leaves show.

Each leaf has deep and smooth curves that dip down from the top, resembling a heart. When the leaves first grow, they appear more circular.

As they mature, they develop their distinct heart shape. The leaf tips are pointy, giving them an elegant look. If you touch them, you’ll feel they are thick and soft, like velvet.

These heart-shaped leaves make the Anthurium clarinervium a beautiful plant that catches the eye.

Leaf Color

Leaf color is an important feature of the Anthurium clarinervium. The leaves of this plant have a deep green color that can catch your eye.

Each leaf displays striking white veins that stand out against the green background. These veins help to highlight the intricate patterns on the leaves, creating a contrast that is both beautiful and unique.

This colorful display makes the Anthurium clarinervium a popular choice for adding a touch of nature’s artistry to home décor.

The leaf color also plays a role in photosynthesis, the process by which plants turn light into energy. Therefore, the vivid green not only looks great but also helps the plant stay healthy.


The Anthurium clarinervium produces flowers that are not like typical garden blooms. Instead, its flowers take shape on a part called a spadix, which looks like a small, pencil-like spike.

The spadix is often a pale yellow or greenish color. Surrounding the spadix is a leaf-like part known as a spathe; it’s a heart-shaped bract that can range from pale green to white.

The actual flowers are tiny and line the spadix, blending in with its surface. They might be hard to spot, as they don’t look like the petals we normally see on flowers.

These blooms can add a subtle touch of elegance to the plant, creating an interesting visual effect even without bright colors.

Stem Characteristics

The stem of the Anthurium clarinervium is the plant’s backbone, supporting the leaves and flowers. It is usually thick and short, providing a sturdy base for the large, heart-shaped leaves to grow from.

The stem’s color can range from a deep green to a kind of pale or even hidden beneath the foliage. It grows upwards before bending under the weight of the leaves, which creates an arching effect that adds to the plant’s visual appeal.

The stem also contains the nodes from where new growth can shoot, making it essential for propagation.

Mature Size

The mature size of a plant refers to how big it gets when it’s fully grown. For the Anthurium clarinervium, it usually reaches a height of about 2 feet.

Its width can spread out to around the same measurement, creating a balanced, symmetrical look. As it grows, this plant will need enough space to accommodate its size.

Keep this in mind when deciding where to place your Anthurium clarinervium in your home or garden.

Care Requirements

Caring for your Anthurium Clarinervium means giving it what it needs to live and grow. Think of it like taking care of a pet; you need to provide the right amount of food, water, and home environment it likes.

Each type of plant has its own favorite conditions, and for the Anthurium Clarinervium, this includes specific light, water, humidity, temperature, and soil conditions.

You’ll need to meet these preferences to keep your plant healthy and thriving. Just like a pet, if you give your plant the right care, it will be happy!

Light Needs

The Anthurium clarinervium thrives in bright, indirect light. Direct sunlight can burn its leaves. Imagine it in its natural habitat under a forest canopy, receiving dappled sunlight.

Place it near a window with a sheer curtain to mimic this, but keep it out of direct sunbeams. This plant’s love for filtered light is like your skin’s preference for gentle morning sun rather than the harsh midday rays.

Too little light will slow its growth and dull its leaf colors. Therefore, finding a balance is key to keeping your Anthurium clarinervium healthy and vibrant.

Watering Frequency

Watering frequency is how often you should give water to your Anthurium Clarinervium. This plant likes its soil to be moist but not too wet. It’s best to water it when the top inch of the soil feels dry to the touch.

Be careful not to overwater, as it can cause the roots to rot. Usually, watering once a week is enough, but you might need to do it more often if the air in your home is very dry.

Always check the soil before watering to make sure it needs it.

Humidity Preferences

The Anthurium Clarinervium plant likes air that is moist. This kind of plant is happiest in an environment that has humidity levels similar to its native tropical forests, which is usually around 60% humidity or higher.

To keep your plant happy, you can mist the leaves with water, put a water tray near the plant, or use a room humidifier. High humidity helps the leaves stay fresh and supports the plant’s overall health.

If the air is too dry, the leaves may turn brown at the tips, which is a sign the plant needs more moisture in the air.

Temperature Range

The Anthurium Clarinervium thrives in warm climates. It prefers temperatures between 65 and 80 degrees Fahrenheit. If the temperature drops below 55 degrees, the plant may stop growing and even suffer damage.

It does not like sudden changes in temperature, so keep it away from drafts and air conditioners. In its natural habitat, the Anthurium Clarinervium is used to a stable, warm environment all year round.

Therefore, maintaining a consistent temperature within its preferred range is crucial for its health.

Soil Type & pH Preferences

The Anthurium clarinervium thrives in soil that lets air reach its roots and drains water quickly. This means its ideal soil is fluffy and light.

It enjoys a mix that includes materials like peat, pine bark, and perlite. The soil’s pH level, which tells how acidic or basic it is, should stay slightly acidic to neutral for this plant.

This is a range around 6.0 to 7.0 on the pH scale. If the soil meets these conditions, your Anthurium clarinervium has a good home to grow healthy roots.

Growth & Propagation

Growth is how the Anthurium clarinervium gets larger and develops over time. Propagation is the process of creating new plants from the parent.

This plant grows at a modest pace and you can make more plants using a few different methods. For example, you can cut pieces of the stem that have at least one leaf and root them in soil or water.

The active growth phase is when the plant is making new leaves and is best for propagation. You should repot the plant when it outgrows its current pot, which can help it keep growing healthily.

Growth Rate

The growth rate of a plant tells us how fast it gets bigger and taller. The Anthurium clarinervium usually grows slowly.

This means you won’t see it shooting up overnight like some other plants might.

Keeping it in ideal conditions helps it grow at its best speed. But even then, it’s more of a steady, gradual process. You’ll need a bit of patience to notice significant changes in its size.

Propagation Methods

To make more Anthurium Clarinervium plants, you can use different methods. Stem cuttings involve cutting a piece of the stem and planting it.

Another way is to separate offsets, which are little shoots that grow from the main plant. They can be gently removed and potted separately.

Last, you might try air layering, which means you wrap a part of the plant’s stem with moist moss and wait for roots to grow before cutting it from the parent plant and planting it as a new one.

Each method needs care and patience to succeed.

Season of Active Growth

The season of active growth for Anthurium clarinervium is when the plant is most lively and grows the most.

This period usually occurs during the spring and summer months, when the weather is warm and there is more sunlight.

During this time, you should give the plant all it needs, like enough light, water, and humidity, for it to grow well.

Remember, during the cooler months of fall and winter, the plant will slow down and won’t need as much care.

Potting and Repotting Recommendations

Potting and repotting are key to your Anthurium clarinervium’s health. Choose a pot with drainage holes to prevent water from sitting at the bottom. Use a light, airy soil mix that drains well.

Repot your plant every two to three years, or when you see roots growing out of the drainage holes. During repotting, gently remove old soil, trim any dead roots, and put the plant in a slightly larger pot.

This allows your Anthurium to grow without getting too tight in its pot. Remember, the best time to repot is during spring, the season of active growth.

Potential Issues

When caring for an Anthurium Clarinervium, you might face some problems. These can include bugs that want to eat the plant or diseases that can show up if conditions are not right.

Sometimes, the plant can be sensitive to changes or mistakes in care. It’s important to know about these troubles so you can keep your Anthurium healthy and happy.

Let’s explore the common pests, diseases, and other sensitivities that might affect your plant. By keeping an eye out, you can quickly handle these issues and help your Anthurium thrive.

Common Pests

Common pests are insects or bugs that can harm your Anthurium Clarinervium plant. These pests often feed on the leaves and roots, causing damage. The most usual ones include:

  • Aphids: Tiny bugs that suck plant juices and can cause leaves to curl or turn yellow.
  • Mealybugs: Small, white, cottony pests that cluster in leaf joints and stem nodes.
  • Spider mites: Almost invisible spiders that weave webs under leaves and can cause yellow speckling.
  • Thrips: Tiny insects that scrape at leaves, leaving silvery trails or spots.

To keep your plant healthy, check regularly for these pests and treat them quickly if you find any.

Common Diseases

Anthurium clarinervium can get sick, just like people. These plants might face issues like root rot when they’re overwatered, showing yellow leaves and a weakened state.

Another disease is called blight, where parts of the plant suddenly turn brown or black and die. Fungal infections can also happen if the leaves stay wet for too long, leading to spots or decay.

It’s important to watch your plant and act quickly if you see any signs of these problems.

Other Sensitivities

The term “Other Sensitivities” refers to the Anthurium Clarinervium’s reaction to certain conditions besides pests and diseases.

For example, this plant can be sensitive to too much direct sunlight, which may harm its leaves. It also might not do well with over-fertilization, as this can lead to a buildup of salts in the soil.

Moreover, if the water has too many chemicals like chlorine, it could affect the Anthurium’s health.

Therefore, it’s crucial to monitor these factors to keep the plant thriving.

Being easy to care for, this plant is great for beginners who want to brighten up a space. Whether it’s in a living room, office, or even a bathroom with enough light, the Anthurium Clarinervium can be a stunning addition.

Just remember to keep it away from pets because it’s toxic if eaten.


Toxicity refers to how poisonous a plant is if ingested or touched. The Anthurium clarinervium is somewhat toxic, especially to pets and children.

It contains calcium oxalate crystals that can cause irritation and discomfort. If someone eats the leaves, they might experience a burning feeling, swelling in their mouth, and difficulty swallowing.

To stay safe, keep this plant out of reach of pets who like to chew on plants and small children. Always wash your hands after handling the plant to avoid skin irritation.

If someone accidentally ingests part of the plant, contact a doctor or poison control center right away.

Additional Tips & Tricks

For example, knowing when to move your plant to a spot with more light can prevent stretching. Or discovering the perfect amount of water can mean the difference between lush leaves and a wilting plant.

These hints can lead to a healthier, happier Anthurium clarinervium.

Fertilization Recommendations

For an Anthurium clarinervium to grow well, it needs the right nutrients. Use a balanced, water-soluble fertilizer, but only during the growing season, which is spring through summer.

Give your plant this fertilizer every six to eight weeks. Always follow the instructions on the fertilizer package to avoid giving your plant too much. Too much fertilizer can harm the roots and leaves of your Anthurium clarinervium.

Remember, during fall and winter, the plant rests and does not need extra food, so you should stop fertilizing until spring arrives again.

Pruning & Maintenance

Pruning and maintenance are like giving your Anthurium Clarinervium a haircut to keep it healthy and looking good. Remove yellow or damaged leaves with clean scissors or shears.

This helps the plant focus its energy on new growth. Pruning also lets more light reach the inner leaves. Do this carefully and don’t cut too many leaves at once.

Regularly wiping the dust off the leaves with a damp cloth keeps them shiny and able to breathe better. Checking the plant during pruning helps you spot any problems early, like pests or diseases.

Remember, a little care goes a long way in keeping your Anthurium Clarinervium happy and thriving.

Support Structures

Support structures are items that help your Anthurium Clarinervium stand upright and grow properly. Just like a ladder helps you reach high places, these supports assist the plant as it gets taller and heavier.

The stems of the Anthurium Clarinervium can become long and might bend or break due to their weight. To prevent this, you can use stakes, trellises, or moss poles that the plant can cling to for support.

By using these structures, you ensure your beautiful plant stays healthy and displays its leaves proudly, rather than drooping or getting damaged.

It’s a simple way to keep your Anthurium looking its best.
