Endemic to Chiapas, Mexico, this plant grows well in high humidity. They are known for their thick, velvet leaves that resemble a heart. This Anthurium is slower growing than its cousin Anthurium crystallinum, which may be the reason clarinerviums tend to be a bit harder to find and more expensive.
Humidity - 60-80% with good air flow. One of the few Anthuriums that can tolerate lower humidity as well.
