Anthurium clarinervium is a fascinating plant. Unlike other anthuriums, it is not cultivated for its flower but for its leaves.
You will learn how to care for your Anthurium clarinervium in this post.
At first glance, Anthurium clarinervium, like many other tropical plants, has an extensive range of occurrences. However, this is not the case.
The velvet cardboard anthurium is found exclusively in Chiapas, a region in eastern Mexico.
In its native habitat, it is an epiphyte, also called a perching plant. That means that it grows on other plants, such as trees.
It belongs to the genus of flamingo flowers (Anthurium) and thus to the family of arum plants (Araceae).
Because of the leaf texture, Anthurium clarinervium is also called a velvet cardboard anthurium.
Appearance and distinguishing features of the velvet cardboard anthurium
The most distinctive feature of Anthurium clarinervium is its heart-shaped leaves. These are thick, dark green, and leathery. The light to-silver leaf veins give a unique contrast.
While young leaves are still small and reddish, an adult leaf can grow up to 30 inches.
The velvet cardboard anthurium has no stem. The leaves spring directly from the rootstock. That leads to a compact growth with a diameter of about 40 inches.
In a year, the exotic grows up to 24 inches. As a perennial plant, it has few delicate roots.
Besides its good looks, it is also said to have air-purifying properties.
Like much other ornamental foliage, Anthurium clarinervium has a rather inconspicuous flower. It consists of a cob which is surrounded by a dark sheathing leaf.
Under suitable conditions, flowering is possible all year round.
The optimal location of Anthurium clarinervium
The location of Anthurium clarinervium should be bright but without direct sunlight.
Optimal temperatures are between 64 °F to 70 °F. Maximum temperature should reach 84 °F. Throughout the year, the temperature should not drop below 54 °F.
There should be no drafts at the location. However, it is very grateful for air circulation.
For the exotic to thrive, humidity is crucial. A humidity of 60 % is sufficient. A humidity of 80% is optimal.
To achieve such humidity constantly and safely, I recommend using a humidifier.
As a slightly poisonous houseplant, the velvet cardboard anthurium should be placed out of reach of children and pets.
Overwintering an Anthurium clarinervium
Over the winter months, the velvet cardboard anthurium can be left in its location. The only thing to watch out for is the heating air. That is not good for it and quickly causes brown leaves.
You may lower the temperature to 61 °F. The critical limit is 54 °F. Fertilizing is not necessary during the winter.
Watering is also reduced. Check with the finger test whether your houseplant needs to be watered again. Only when the top layer of soil has dried out is it time to water again.
Watering the velvet cardboard anthurium
Regular watering helps to keep the substrate of Anthurium clarinervium evenly moist. It is critical to avoid waterlogging, as delicate roots are prone to root rot very quickly.
For watering, I recommend using lime-free water, such as rainwater.
Fertilizing Anthurium clarinervium
Fertilizing can be done at 4 to 6 weeks during the growing season from spring to fall.
For fertilizing, I advise applying a No products found. with the watering in half dose.
Every two to three months, it is advisable to rinse the roots. That is done to remove the salts that have built up through fertilizing.
Rinse for 2 to 3 minutes under running water.
The optimal substrate
Excellent drainage is necessary for delicate roots. It is equally vital that enough air gets to the root ball and only loosely surrounds it. The pH value should be between 5.5 and 6.5.
Orchid soil combines these properties best. Even better is a self-mixed aroid mix.
The best time for repotting is spring. Repotting is done in a rhythm of 2 to 3 years or whenever the pot is thoroughly rooted.
When repotting, it is advisable to renew the substrate to continue to ensure a good supply of nutrients.
When repotting itself, there is not much to consider. Only the sensitive roots need some attention. When repotting the plant, Anthurium clarinervium should be planted only as deep as before.
Pruning the velvet cardboard anthurium
The velvet cardboard anthurium does not need a topiary. However, you should permanently remove dead and dying plant parts.
For pruning, I recommend using a sharp and clean blade. That will prevent bruising and reduce the risk of infection. It is essential to wear gloves when cutting because the sap is also poisonous.
Propagate Anthurium clarinervium
The best way to propagate the exotic is by division. The optimal time for propagation is repotting in spring.
You can start dividing as soon as the houseplant has formed several shoots.
First, remove the velvet cardboard anthurium from its pot and carefully remove the substrate. Then divide the root ball into 2 or 3 parts. Each part must have at least one shoot with leaves and roots.
After that, the parts are planted in individual containers.
It is important not to fertilize this year. Also, Anthurium clarinervium will not produce flowers this year.
