Anthuriums (Anthurium andraeanum) are tropical perennials popularly grown as houseplants. Native to tropical America, they are also often called "Flamingo plants." Desirable for their large, heart-shaped spathes (modified leaves), these foliage plants come in shades of white, pink and red, according to information published by the University of Florida. Red varieties include "Red Hot" and "Red Angel." The care of these spectacular crimson beauties does not differ from other anthurium cultivars.
Plant your red anthurium in rich, organic soil that drains well. The soil should be loamy with some sand and organic matter added, according to the University of Florida.
Set your anthurium red plant in a location where it will receive bright, but not direct sunlight. Direct sunlight scorches the leaves of the plant and fades the bright red color of the spathes, according to information published by the University of Florida. Instead, place your plant near a window with light filtered by a curtain or where it is exposed to gentler morning sun followed by afternoon shade.
Water only when the first few inches of soil become dry. These flowers prefer to be on the dry side and can even tolerate short periods of drought. Overly wet or soggy soil quickly leads to root rot, a fungal disease of the roots.
Put the plant in a warm place. These flowers bloom much better if kept in relatively warm temperatures, according to information published by the University of Florida. Nighttime temperatures in the high 60's and low 70's Fahrenheit, with daytime temperatures 10 to 15 degrees higher, are perfect for anthuriums.
Keep the air humid. Place your red anthurium on a shallow tray filled with pebbles that are just barely covered with a layer of water. The water evaporates, adding important humidity to the air. Without at least 50 percent humidity in the air, the plant loosees its shine and may even drop some leaves, according to the University of Florida.
