Anthurium Clarinervium: 1 Secret to Growing Them

Some of the links in this post may be affiliate links.

Anthurium clarinervium is a stunning foliage houseplant in the Aroid family and is sure to stop you in your tracks with its dark green, deeply lobed heart shaped leaves and contrasting white veins.

I’ll tell you how I care for mine and also discuss Anthurium care in general. It’s a fascinating genus and one that is growing in popularity among houseplant collectors (if you can find one, that is!)

Anthurium clarinervium is native to Mexico and grows as an epiphyte. Since it is an epiphyte, it has special potting soil needs which I’ll discuss soon!

They do flower, and will look similar to many aroid family flowers in that they have both a spadix and a spathe, but they are insignificant on Anthurium clarinervium.

These plants clearly are grown for their striking, leathery, thick foliage.

Many species in the Anthurium genus can get prohibitively large inside the home. The clarinervium is a smaller growing species that is perfect to grow in the home! Indoors, the leaves will grow to about 6″ or a little larger.


These plants enjoy mostly bright indirect light or filtered sunlight. Keep these plants away from too much direct sun. A little bit is fine.

An exception is in the winter time if you live in areas with much shorter and cloudier days like I do. During those months, some direct sun will greatly benefit these plants.

My own plant sits in an Eastern facing window so it get some morning sun. In the summer, I place the plant outside in complete shade.


Anthuriums love and thrive in warm temperatures. Aim to keep them at 70-90F (21-32C) if you can. I keep mine in my sunroom and it does get into the 60s (F) in the winter but I wouldn’t go much lower than that.

Anthuriums love high humidity and are really best grown in a greenhouse, but you can grow them successfully indoors with some attention.

If your indoor winter air is dry as a result of forced air heat inside your home, I would highly recommend getting a humidifier. I experimented with different humidifiers and found one that I LOVE.

I run it from about October (or whenever we turn our heat on in the house) until April or May so (when we normally shut off the heat).

Do you need a good humidifier? I’m thrilled with mine, so if you need one, read my blog post where I talk about humidity and houseplants, and my absolute favorite humidifier.

I’ve tested tons of humidifiers and I talk about the best one I’ve come across. I use it on-stop during the winter!


Anthuriums, like many orchids, are epiphytes so they grow on trees and tree branches. They are often drenched in nature from frequent rains, but they will dry out quickly because their roots are much more exposed because of the way they grow.

This is what you must reproduce in the home in order to be successful.

Don’t let these plants sit in water or it will spell death and they will rot. After you water thoroughly, make sure you discard excess water. Let it ALL drain away. Don’t let any sit in the saucer underneath.

Don’t water again until the top inch or two of the potting mix is dry. Just use your finger to determine that.

You’ll want to try to keep most of the potting mix lightly moist, with the top couple inches being dry and the rest of it being barely moist. If it is still wet underneath, don’t water. Wait longer and check your plants regularly!

You can’t just have good watering techniques though. Epiphytes like Anthurium demand an appropriate potting soil as well in order to thrive.


Since these plants are epiphytes, they require fantastic drainage. To accomplish this, I like to add orchid bark to my potting mix. This is the “secret” to growing these plants.

You can start with 1 part of orchid bark to 2-3 parts of whatever all-purpose peat-based houseplant potting soil that you like to use. This will provide the amazing amazing drainage that they need to thrive.

You can also throw a handful of perlite in the mix for good measure.


Fertilize throughout active growth in the Spring and Summer time. I like to fertilize dilutely with every watering (or almost every watering).

My favorite houseplant fertilizer is Dyna-Gro Grow and I purchase on Amazon. I add 1/4″ teaspoon per gallon of water and use it on all my leafy tropicals.

It is an amazing, COMPLETE fertilizer and is urea-free so it won’t burn your plants. I highly recommend this fertilizer and I’ve had great results from using it.


Since these are epiphytes, they love air circulation. Think about it. In nature they’re growing on the side of cliffs, rocks, and on trees, so they’re exposed to a good amount of air circulation.

Air circulation will benefit all plants, but especially epiphytes like Anthuriums. I’m not talking about cold drafts though 🙂 You’ll want to avoid those.

I like to gently circulate the air in my sunroom with my ceiling fan. I’ll turn it on low and it will provide circulation for my Anthuriums, orchids, and all the other plants.

If it is warm outside, open a window for air circulation. Or better yet, let it sit outside for the summer in the shade to get the benefit of rainwater, natural air circulation, and higher humidity levels.


Propagation is best done by division when you repot, if your Anthurium has more than one stem. Gently loosen the roots and tease apart any new section of growth.

Make sure each division has roots and at least 1 or 2 leaves of its own and pot it up separately.

Where to Buy Anthurium Clarinervium

This is the real challenge! This is a very hot plant that is both expensive and difficult to find. Most websites that you find will have the dreaded “out of stock” phrase next to Anthurium clarinervium.

Regardless, here are some sources to keep your eye on and you can even get on the waiting list for some of them. They are both fantastic companies and I’ve had great experiences with both of them.

NSE Tropicals in Florida has an amazing array of tropical plants and I highly recommend them.

PA Orchid Exchange is where I purchased mine, but it is not a regularly stocked item (but then again, it probably isn’t a regularly stocked item anywhere!). Mine was beautifully packed when I received it.

If you’d like to know how I grow the “common” Anthurium that you see everywhere, check out my Anthurium Care: Growing Flamingo Flower blog post. I’ve had this plant below for over 15 years and is one of my oldest and most prized plants.
