Anthurium crassinervium plants require frequent, but light, watering. During the growing season (from March to October), water your anthurium twice a week in order to keep the soil lightly moist. During the winter (from November to February), water the plant once every 10 days. It's important not to overwater your anthurium, as the plant is susceptible to fungal and root rot. When watering, allow the water to run through completely, and then wait a few days before watering again. Additionally, make sure to use well-draining soil for your anthurium, as this will help prevent overwatering.


Anthurium crassinervium, also known as the painted tongue or black velvet anthurium, is a species of flowering plant that requires full to partial sunlight for optimal growth. For optimal health and flowering potential, they should receive 3-4 hours of direct sunlight per day, spread out throughout the day. The morning and late afternoon are best for providing the bloom with the full light intensity without increasing the heat. If your anthurium is getting too much sunlight, its leaves may scorch. Too little sunlight, and the plant will become weak and not thrive. Therefore, it is important to find the right balance of sunlight for your plant.


Pruning an Anthurium crassinervium should be done once or twice a year during its growth season– Spring or Summer. Pruning should be done cautiously, removing no more than 1/3 of the plant’s foliage. Doing so will help the plant attain better shape and increase yield. Additionally, any stems that are brown, yellow, or broken should be snipped off to encourage healthy growth.

Is it challenging to grow anthuriums from seeds?

Yes, it can be challenging to grow anthuriums from seeds. The seeds are very small and recovering them is not an easy task, as they often need to be extracted from existing blooms. Additionally, anthuriums need the proper care and environmental conditions to thrive, and maintaining these can be difficult. As a result, propagating anthuriums from seeds is often much more difficult than propagating them from cuttings.

Are anthuriums easy to propagate?

Anthuriums are relatively easy to propagate, especially as cuttings. All you need to do is select a healthy stem and cut it about 3 cm below the node. The node contains the hormones needed to create roots. Place the cutting in a pot filled with well-draining soil, keep the soil moist and in a warm place, and it should develop roots within a month. There are also other ways to propagate Anthuriums, such as division. This involves splitting large clumps of the plant and replanting evenly.

Should anthuriums be grown indoors or outdoors?

The answer to this question depends on the climate of your area. Generally speaking, anthuriums prefer warm and humid weather, so if you live in a warm climate, then outdoors is usually the best option for growing this plant. If you live in a colder climate, then indoors is usually the best option. An anthurium's ideal temperature range should be between 60 and 90 degrees Fahrenheit. Planting them in a pot, rather than outdoors in a garden, is preferable as they do not take well to colder temperatures, and they can be moved indoors during cold snaps. Indoors they should be given bright, indirect light, along with consistent moisture, in order to thrive.

Could anthuriums be grown in a terrarium?

Yes, anthuriums can be grown in a terrarium. This is a great way to create a miniature, tropical-inspired environment to showcase the plant’s exotic foliage. They won’t require as much maintenance as a typical houseplant terrarium and they will thrive in a terrarium as long as it is kept relatively moist. When growing anthuriums in a terrarium, it is important to ensure it is not kept too wet, as anthuriums don’t tolerate soggy soil. Furthermore, it is best to position the terrarium close to a window to provide adequate light while still protecting the plant from direct, harsh sunlight. An adjustable LED lamp may also be used. Additionally, when using a potting mix, make sure it is aired and free of debris.

Do anthuriums require high humidity?

Yes, anthuriums require high humidity to thrive. They are tropical plants, native to areas of South and Central America that are full of jungle-like humidity. In order to best replicate this in your home, you can move your anthurium to a humid location like the kitchen or bathroom, or you can increase the humidity of its environment with regular misting or use of a humidifier. Additionally, grouping together several plants can increase the humidity around them.

Is it possible to grow anthuriums in a hydroponic system?

Yes, it is possible to grow anthuriums in a hydroponic system. When grown hydroponically, anthuriums can more easily absorb water, nutrients, and oxygen, allowing for stronger, healthier plants. To properly grow them in a hydroponic system, the roots should be suspended in a solution of a nutrient-rich water, and the temperature should be kept between 65 and 85 degrees Fahrenheit. Additionally, anthuriums should be grown under filtered light and require regular pruning and monitoring. With careful attention and tailored growing techniques, anthuriums can be successfully grown in a hydroponic system.

Could anthuriums be grown as hedge plants?

Yes, anthuriums can be grown as hedge plants. They are full of lush foliage, which makes them aesthetically pleasing. They require little maintenance and rarely need trimming or pruning. They’re also extremely hardy and make for a great low-maintenance option for creating a living barrier around the home. Even better, anthuriums are extremely attractive and come in a range of colors, from white and pink to red and dark green. They can really liven up an outdoor space and add some vibrancy to any garden.

Is it necessary to repot anthuriums annually?

No, it is not necessary to repot anthuriums annually. While it is beneficial from time to time to repot anthuriums in order to give the plant access to fresh potting soil and more space to grow, anthuriums do not need to be repotted every year. An anthurium’s growth rate and root system is slow-growing and thus, can go a couple of years between repotting. If an anthurium's roots are crowded and spongy, then it can indicate that it is too root-bound and should instead be repotted.
