Anthurium

Anthurium clarinervium

Velvet Cardboard

Family: Araceae

Genus: Anthurium

Species: Clarinervium

Cultivars: None

Common names: Velvet Cardboard, Velvet Leaf

Difficulty: Medium to high

Description: This plant lives up to its common name! It is hard as cardboard and has a velvet sheen atop its spade shaped leaves that grow in a bushing format. The leaves are dark green with an almost minty hue in the veins. New growth starts out orange and fades to the deep green over time. It is a great introduction to this difficult, but beautiful genus. 

Mature size: This plant is a smaller member of the notoriously large-leafed genus of Anthurium. It will get up to 30 inches tall and wide, with leaves getting about 4 inches across. 

Light: Bright indirect light. Under a grow light or a West or South facing window. Avoid direct sunlight as the plant can be burnt.  

Water: This plant wants a deep watering when 50% dry. It is better air on the size of being too dry. 

Temperature: Ideal between 60-95 degrees Fahrenheit. Avoid temperatures below 55 degrees.

Humidity: This tropical plant will require additional humidity than most people’s homes will provide. Use a humidifier, greenhouse cabinet (our preferred method). 

Soil: A rich airy mix is needed for Anthurium. We use 2-parts coco coir, 2-parts perlite, 1-part charcoal, 1 part bark, ½-part worm casting.

Nutrition: The Anthuriums need regular feeding during the growing season. Fertilize monthly at half strength May through September or year-round if grown under grow lights. 

Repotting: This plant will only require repotting when the roots are escaping the bottom or top of the planter. Even then you may want to wait. They thrive being root bound. This plant will require drainage holes in the planter. 

Toxicity: Non-toxic to humans, dogs, and cats. Mildly poisonous to humans, dogs, and cats, causing gum bleeding, nausea, vomiting, diarrhea, and stomach upset. While it is not considered fatal, please contact your doctor or vet if consumed. They may not be familiar with the species; however, they should be familiar with the genus and family of the plant. 

Native to: Mexico

Companion Animals: This plant is not recommended in animal habitats as it is expensive and meant for collectors.
