Houseplants are a terrific way to add beauty to any indoor room, whether the room is an office, living room, or even a guest bath. Not only are houseplants attractive, but they also add oxygen to the air. Many filter out harmful toxins. Red flowering houseplants are especially attractive during the holidays, or in a room that needs a cheerful splash of color.
Anthuriums are exotic, tropical plants desirable for their highly glossy and colorful bracts. The bracts surround the spadix, which is a tall "tail" covered with tiny flowers. Anthuriums come in shades of pink and white, but the showiest are a rich, bright red. They are usually grown as houseplants because of their warm-temperature requirements, ability to survive periods of drought, and tolerance for low light. These showy flowers will flower continuously if given proper care, according to the University of Florida.
Hippeastrums are flowering bulbs, the most popular of which is the giant amaryllis. These flowers are most commonly grown in containers. The bulb should be placed in an 8-inch container, with half the bulb (neck up) protruding above the surface of the soil. If the soil is kept moist, the flower will bloom about five weeks later. Morning sun exposure is best for these flowers, according to the Missouri Botanical Garden. Hippeastrums come in shades of red, pink and white. The "Red Lion" variety is especially popular around Christmas.
Guzmania is a genus of bromeliads, which make excellent indoor plants, according to the University of Florida. These plants need very little care in order to thrive, and will grow in low-light conditions. Guzmanias have thin, shiny, slender leaves that wrap around to form a rosette. This rosette holds water, allowing the plant to tolerate long periods of drought. Guzmanias bloom with red, yellow or orange flowers clustered on a spike and surrounded by bracts in the same color. G. lingulata, or "Scarlet Star," is a popular red variety.
