Anthurium Crystallinum (Crystal Anthurium) Plant Care

What is Anthurium Crystallinum?

Anthurium crystallinum is a large-leafed plant that belongs to the Anthurium species and Araceae family.

Anthurium crystallinum is a hybrid plant cross between an anthurium and a tulip. It produces a robust color palette with anthurium-like features, including glossy green leaves and rich red flowers.

The love this plant gets from gardeners is because its velvety leaves and striking white veins make it a stunning plant in every home.

Due to their large size and shaped leaves, some have been described as resembling “a giant green umbrella.”

The Anthurium crystallinum plant is also known as the Crystal Anthurium. It is native to Central and South American rainforests, where it grows as an epiphyte or terrestrial plant on trees or rocks in montane forests.

Where crystallinum grows best depends on the location. In USDA zones 10-11, they flourish as outdoor plants.

This flowering plant is best grown in moist but well-drained soil. The plant thrives when provided with high humidity and shade in the summer, while it likes to be partially shaded in the warmer months.

They can even be grown indoors if set in a bright, sunny location with plenty of water and humidity.

In addition to its attractive foliage, this species has gained popularity for its ability to grow into very tall specimens that reach heights of up to 3 feet (1 meter) tall.


In this blog post, you will learn how to care for your crystal anthurium, such as watering it and feeding it. You can also learn more about the different types of anthuriums that you can grow in your garden.

How to care for Anthurium Crystallinum

Temperature and Humidity

Anthurium crystallinum is a large-leafed plant that belongs to the Anthurium species and Araceae family.

The love this plant gets from gardeners is because its velvety leaves and striking white veins make it a stunning plant in every home.

Naturally, you can find Anthurium growing in Central and South America, but what makes this plant unique is that it can adapt anywhere when shown care.

Where crystallinum grows best depends on the location. In USDA zones 10–11, they flourish as outdoor plants.

However, in other regions, indoor plants suit them. Although this tropical plant is a slower grower, the result of caring for Anthurium will satisfy you.

You will have a healthy plant that will grow as tall as 3 feet (90 cm) with beautiful foliage.

More so, Anthurium crystallinum care requires you to place this plant in humid air since dry air can lead to the development of brown leaves.

If it’s dry, mist the air when it’s dry, or use a pebble tray to humidify Anthurium Crystallinum.



For Anthurium crystallinum care, you must know that this plant loves light. Seize advantage of the summer and expose it to bright, indirect light.

Providing shade is also great because no matter how much the Anthurium crystallinum plant enjoys light, it does not tolerate direct sunlight.

The plant can burn or develop yellow leaves when exposed to intense sunlight.

You can provide shade for the crystal Anthurium by keeping it under a tree outdoors or near a window with blinds or curtains.


The recommendation is to water the Anthurium crystallinum plant regularly during the summer and less in the winter to help it thrive.

Overwatering this plant can cause root rot, so water with caution.

The best method to consider when watering this plant is the soak and dry technique since it has proven effective.

Do the soak and dry style by watering it thoroughly and ensuring that the soil is dry before going again.

While the motive is to avoid excessive watering, many plant owners have become overzealous about it, thus starving Anthurium crystallinum of water.

It is wrong to let your plant get too dry, as it can cause it to wilt away. Always keep the soil moist.


Fertilizing is not necessary to grow Anthurium crystallinum. However, using a little in the growing season to encourage flower growth is not a bad idea.

To feed your garden plants, use a diluted amount of organic fertilizer rich in nitrogen and phosphorous.

In either situation, try to avoid applying chemical fertilizers as they could lead to the salinization of your plant.

Alternatively, you can use a slow-release fertilizer. They are easy to use because you stick them in, and that’s it—no fussing about overfertilizing. We highly suggest this slow-release fertilizer.

Soil and Repotting


The kind of soil you grow Anthurium crystallinum on can be any soil, but make sure it doesn’t hinder its growth.

This plant does not tolerate excessively moist soil because it causes root rot and infection.

Hence, Anthurium crystallinum requires slightly acidic soil with suitable drainage holes.

To achieve this, use a potting mix of sphagnum moss, orchid bark, pine bark, or coconut coir mixed with peat moss.

You can repot Anthurium crystallinum every two years.

This plant will not be hurt while being root-bound; Unless it is growing off the pot and not absorbing water properly, there is no need to repot the entire plant.

We always use this houseplant potting soil for our plants. It’s nothing special, but it seems like all our plants are happy with it.

There are two easy ways to propagate Anthurium crystallinum. They include; root division and stem cuttings.

For stem cutting propagation, use a sterilized object to cut off the stems from the mother plant.

When the cuttings have healed, root them in clean water and expose them to bright, indirect light.

In a few days, this plant should start developing.

Propagation by root division involves a similar process, except that you only have to look for the offshoots and separate them this time around.

Common Pests and Diseases

These tropical plants are susceptible to lots of attacks from pests and diseases.

However, there is proof that most of the infestations are because of overwatering.

These pests and diseases are mealybugs, bacterial blight, Pythium fungal infection, etc.

To eradicate this infection, you need to stop overwatering your plant.

Also, another recommendation is to be observant because most of these infections are not immediately noticeable.

When they become visible, your plant is already in danger, and there is nothing you can do except cut the infested part off or use Neem oil.

If you are looking for a Neem oil spray, we suggest this Neem oil spray. We know it’s effective because we’ve used it on our pest infestations; it simply works.

Anthurium crystallinum plants are a type of aroid with a stocky, green leaf that can grow to be up to 3 feet in height.

Since this plant is native to the tropical rainforests, they will thrive if you plant them in partial shade and provide regular watering.
