About

Anthurium clarinervium is a species of flowering plant in the family Araceae native to Chiapas, Mexico. The Anthurium genus is known to contain approximately 1,000 species, resulting in one of the most diverse Central American tropical plant genera.

How to grow it

Although it grows naturally in tropical climates, many people find it to have attractive qualities, resulting in a high demand as a house plant. This plant exists in both a horticultural environment and in a tropical, natural environment. People enjoy the look of this species because it can bloom for several months and because of its unique foliage. Anthuriums can be challenging as houseplants because it is not easy to match the conditions of their natural environment in houses. But because an Anthurium is an epiphyte, they can survive many different habitats that are not similar to their normal humid rainforest environment.

Bright, indirect sunlight is required for this plant. It prefers temperatures from low 70 °F (21 °C) to low 80 °F (27 °C), and humidity at 50% or higher, optimally 75-85%. The plant do not do well in small amounts of light, and veins can then lose saturation. It also does not do well in direct sunlight, which may cause burns on foliage. Modest fertilization is necessary for this plant to flourish.

Safety

Anthurium clarinervium is poisonous to both humans and common pets upon ingestion. Toxic harm results from the presence of calcium oxalate crystals in the leaves which can cause improper mineral absorption and inflammation of the lining of the digestive tract. Ingesting this plant can cause drooling, nausea, trouble swallowing or breathing, diarrhea, and pain in the mouth and throat. Remedies include removing all parts of the plant, and rinsing out mouth with either milk or water. The calcium in the crystals and milk will bind together and reduce pain.

Where it grows

Anthurium clarinervium tends to grow in wet disturbed forests or elevated cloudy environments. It is found naturally in Mexico. Anthurium clarinervium is an aroid perennial that flourishes in shaded regions of Mexico’s limestone ledges.
