Botanical name: Anthurium Clarinervium
Commonly known as: Velvet Heart Anthurium
If there were an award for the most elegant foliage plant, Anthurium Clarinervium would be right at the top of the list.
Native to the limestone cliffs of southern Mexico, this remarkable aroid has evolved thick, leathery leaves that feel almost like suede. Each perfectly heart-shaped leaf is a deep emerald green with brilliant white veins that stand proudly above the surface, creating a pattern that almost looks hand-painted.
Unlike many Anthuriums that are grown for their flowers, Clarinervium is all about the foliage. Every new leaf emerges larger, darker and more dramatic than the last, making this one of the most rewarding collector plants you can grow.
Despite its luxurious appearance, Anthurium Clarinervium isn’t difficult once you understand what it enjoys. It naturally grows as a lithophyte, anchoring itself into rocky limestone outcrops where water drains away quickly and fresh air constantly moves around the roots. Because of this, it appreciates a loose, airy growing medium far more than heavy potting soil.
Given warmth, bright filtered light and consistent care, this plant will reward you with stunning leaves that continue increasing in size year after year. Mature specimens become true centrepieces and are often the highlight of even the most impressive aroid collections.
If you’re looking for a plant that makes visitors stop and ask, “What on earth is that?”, Anthurium Clarinervium rarely disappoints.
Anthurium Clarinervium Care Guide
Watering – How often should I water it?
Allow the top few centimetres of the growing medium to dry slightly before watering again.
Clarinervium enjoys consistent moisture but absolutely dislikes sitting in wet soil. Good drainage is far more important than frequent watering.
Reduce watering during winter when growth naturally slows.
Light – Where should I place my Anthurium Clarinervium?
Bright, indirect light is ideal.
Place it close to a bright window where it receives plenty of filtered light throughout the day. Avoid harsh afternoon sun, which can scorch the velvety leaves.
Humidity – Does it need high humidity?
Yes. While it will tolerate average indoor humidity, Anthurium Clarinervium performs best when humidity remains above 60%.
Higher humidity encourages larger leaves and helps prevent crispy leaf edges.
Soil – What growing medium should I use?
Excellent drainage is essential.
I recommend Milled Bark Growing Medium as the primary growing medium. It provides outstanding airflow around the roots while retaining just enough moisture for healthy growth.
If you prefer an even more open mix, you can incorporate Perlite.
Feeding – How should I fertilise it?
Â
Feed every 4–6 weeks during spring and summer using Grobest Organic Fertiliser.
To encourage larger leaves and vigorous growth, feed regularly with Novatec Soluble Fertiliser throughout the growing season.
Repotting – When should I repot?
Â
Repot every 18–24 months or once the roots begin filling the pot.
Refresh the growing medium using Milled Bark Growing Medium and incorporate TerraPlus Natura N together with Controlled Release Fertiliser.
Only increase one pot size at a time.
Pests – What should I look out for?
Inspect regularly for spider mites, thrips and mealybugs, particularly underneath the leaves and around new growth.
Good airflow and healthy growing conditions greatly reduce pest problems.
Temperature – What’s the ideal temperature?
Anthurium Clarinervium grows best between 18°C and 28°C.
Avoid temperatures below 15°C and protect the plant from cold drafts.
FAQ’s
Why are the leaves so thick?
The thick leathery leaves help the plant conserve moisture in its natural habitat, where it grows on rocky limestone slopes with excellent drainage.
Is Anthurium Clarinervium difficult to grow?
Not at all. Most problems come from overwatering or using dense potting soil. Give it warmth, bright filtered light and an airy growing medium, and it becomes surprisingly easy to care for.
Will the leaves get bigger?
Yes. As the plant matures, each new leaf usually grows larger than the previous one, provided it receives enough light, warmth and nutrition.
Does it flower?
Yes, although the flowers are small and fairly insignificant. Almost everyone grows Clarinervium for its spectacular foliage.
Is it pet safe?
No. Like other Anthuriums, it contains calcium oxalate crystals and should be kept away from pets and young children if ingested.
