Anthurium Clarinervium Matuda Origin 

The anthurium clarinervium matuda is from the genus anthurium and was only discovered in the 1950s.  This is because it is from a small region in Chapas, or southern Mexico.  In the wild, it only grows on karst formations (limestone/dolomite outcroppings) at an elevation of 2500-3800 in tropical forests.  There are reports of some specimens in the Colón Province of Panama 

Some people consider this anthurium plant to be epiphytic.  Anthurium clarinervium matuda does not grow in trees.  It is not an epiphytic but a lithophyte.  It gets its nutrients from leaves and other debris that are in the water it receives from rain.  This Anthurium clarinervium plant has a very strong root system so that it can wedge itself in cracks in the rocks.

How to Care for Anthurium Clarinervium Matuda 

Anthurium clarinervium matuda is a bit temperamental and is not really a plant for novices.   Intermediate and advanced growers should have no trouble, if they are willing to cater to the plant’s needs.

Light and Temperature

Anthurium clarinervium matuda does not grow well in very hot areas or very cold ones.  It needs a temperature of 68-80 F to thrive.  It will die if the temperature falls below 55 F.  When it is above 90F you will see dry, faded leaves.  Anthurium clarinervium matuda grows well in bright, indirect sunlight.  Direct sunlight will burn the leaves. 

Water and Humidity

Anthurium clarinervium matuda needs its soil to be damp but not soggy.  If it is too wet, the crown will rot, or it will get other problems.  Do not get the leaves wet as that increases the chance they will be damaged or diseased.   

The plant also needs a high humidity environment where the humidity is 60% or higher.  To really thrive, it needs around 80% humidity.  For this reason, many people grow anthurium clarinervium matuda in the bathroom where the shower or bath keeps the room high in humidity.  You can also mist the plant frequently to increase the humidity in its area of the house. 

If you have a saucer, you can put pebbles in the saucer and then fill the saucer with water about 3/4s of the way up the pebbles.  Place the pot on the pebbles and as the water evaporates, it will cause a humid microclimate.  Just be sure that you keep the water level up in the saucer. 

If you are really serious about raising many anthurium clarinervium matudas, you can use a humidifier.  This is a more expensive option, and you do have to constantly add water and make sure the humidifier is clean with no mold in it.  Some people have all their plants in one room, which makes a humidifier more practical. 

Fertilization

These plants need to be fertilized every 4-6 weeks during the growing season and every 6-8 weeks when it is dormant.  Using a water-soluble fertilizer makes it easy to fertilize at the same time as you water.  Pick a balanced fertilizer such as a 10-10-10 that is for acid loving plants.  Every three months or so, put your plant under tepid water for several minutes to wash the mineral salts that accumulate in potted Anthurium clarinervium matuda.  Otherwise, they build up and become toxic to the plant.

Flowering

This plant has both male and female flowers, but the males form first so that it can’t pollinate itself.  If the flowers are pollinated, anthurium clarinervium matuda produces green berries that take almost a year to ripen.  When ripened, the berries turn orange and drop off the plant.  You can then save the seed. 

Pruning

Unless you are pruning out dead or diseased leaves, anthurium clarinervium matuda should not need pruning.  It naturally has a pleasing habitat. 

Repotting

The anthurium clarinervium matuda needs to be repotted every 2-3 years.  Since it is found on rocks, it needs a very fast draining growing medium.  Using potting medium intended for orchids works well. 

If you want to mix your own potting medium, you will need Douglas fir bark, sphagnum peat moss, and perlite.  Mix one part Douglas fir bark to five parts sphagnum peat moss and five parts perlite. 

The perlite holds some water while the sphagnum peat moss adds an acidic element, and the Douglas fir bark lets the roots grow through the medium easier.  The plant likes the pH to be between 5.5-6.5. 

Anthurium clarinervium matudas can grow up to three feet high and spread out four feet if they get optimal care.  The leaves of the anthurium clarinervium matuda can get 8-10 inches long.  

The plants will last about five years, but you can begin dividing them or vegetatively propagating them when they reach about two years, so they never really die even though the parent plant is no longer alive.  

Pests  

The major pests of anthurium clarinervium matuda  are spider mites, mealybugs, scale, thrips, aphids, and whitefly.  These are primarily sucking insects as piercing insects can’t do much with the thick, leathery leaves. 

It is a good idea to inspect your plants regularly for pests and take action as soon as you find any.  Remember to look on the back of leaves, the crown where new growth begins, and the crotches of the leaf stalks.  If you find pests, you can treat the plant with neem oil to kill them.  This is an organic oil that smothers the pests. 

Diseases 

Anthurium clarinervium matuda suffer from leaf-spot disease, rust, botrytis & root rot.  The root rot is caused by over watering.  Sooty mold forms on the leaves in the honeydew, or excrement, from the pests.  While not fatal in and of itself, enough can make it hard for the chlorophyll to photosynthesize energy for the plant.  It also looks bad. 

The best way to keep diseases and pests from getting on your plants is to keep new plants that came from outside your home in quarantine for a week to ten days.  That way, if they do have pests or diseases, you can keep them from spreading to the rest of your plants.  It is better to discard buggy or sick plants than let diseases or pests spread throughout your house and plant collection. 

How to Propagate Anthurium Clarinervium Matuda 

The anthurium clarinervium matuda can be propagated by division, cuttings, and seeds.  Division is the preferred method. 

Propagate by Division

When you repot your plant, divide it into pieces that each have a leaf stalk, tuber, and roots. You can find a node and break the tuber there by flexing the tuber downward.  You can also use a sharp, clean knife to cut them apart. 

Be sure to wash the blade in 1-part bleach and 9 parts water between every plant so you do not transfer diseases to them.  After you separate the plants, plant them normally in separate pots.   

Propagate from Stem Cuttings

To propagate anthurium clarinervium matuda from stem cuttings, use clean shears or scissors to cut a piece of new growth that is about four inches long and is just above a leaf node. 

Cut off the lower leaves. Put the cutting in a jar with water in it.  Place the cutting in bright indirect sunlight. 

When the roots are two inches long, remove the stem from the water and let it drain on paper towels for 12-24 hours, so it is completely dry before planting. 

Plant it in moist soil.  Put a clear plastic bag over the plant to keep the humidity high.  Return the plant to the bright indirect light. 

The plastic can be removed when new stems start to grow.  The best time to do this is in early spring. 

Propagate from Seeds

To propagate from seeds, you will either need two plants which can fertilize each other or to buy seed.  The berries can take up to a year to ripen.  Each berry has one seed in it. 

Let the berries dry on the stalk.  Take the dried berries and wash them several times to get the sticky pulp off of the seeds.  Dry the seeds by placing them on a paper towel for several hours. 

Plant them in a finer potting medium than the adult plants like.  Give them similar light and water as the adults.  They germinate in 5-8 days. 

When they have two true leaves, they are ready to be planted in a regular pot with the normal potting medium.  Be careful, as they are fragile. 

Anthurium clarinervium matuda do not grow very fast from seeds, so it will be a while before the seedlings look like their parents.

Frequently Asked Questions 

If you still have some questions about the anthurium clarinervium matuda, you are not alone.  Here are the answers to the most common questions. 

Anthurium clarinervium matuda are considered slow to moderate growers.  If their needs are met, they can grow faster.  However, it is picky.  If the light, water, temperature and humidity are not just right, it will grow very slowly.  That is its way of telling you it is unhappy. 

If your anthurium clarinervium matuda is leggy, you can cut it back.  It will take a while to come back, but it will be much fuller when it does.  If the plant is leggy, it means it is not getting enough light. 

Anthurium clarinervium matuda makes a very nice houseplant.  For those who do not live in a tropical rainforest at high altitude, it is the only way to raise anthurium clarinervium matuda.  They are only hardy to USDA zone 9a-11. 

Coffee grounds can be substituted for peat moss in the growing medium.  They acidify the medium in the same way as the sphagnum peat moss, but don’t go overboard with them as the soil can get too acidic.  Using coffee grounds is better than cutting sphagnum peat moss from the bogs as far as the environment is concerned. 

Misting is a great way to increase the humidity in the air.  Anthurium clarinervium matuda appreciates the higher humidity it creates.  It also makes the leaves glisten. 

Your plant is getting too much water.  You want the soil to be moist, but not soggy.  Reduce the amount of water you are giving your plant.

The humidly is too low.  Tropical plants cannot function with a low humidity.  It must be at least 60% and ideally 80% humidity. 

This happens when the plant is not getting enough light.  The growth will also be stunted because the plant does not have enough light to photosynthesize the food it needs for its leaves.  Be careful not to turn around and give it too much light, as that will burn the leaves.

Yes, it is toxic to humans and pets.  They contain insoluble calcium oxalates that can cause ulcers in the esophagus and stomach if ingested.  In humans, oral irritation, swelling, and chest discomfort have been reported.  Keep this plant where children and pets cannot get to it.
