Anthurium–commonly called the Flamingo flower–gets its name from the graceful, arching protrusions of brightly colored bracts. It adds tropical flair to any bright, sunny spot indoors. The bracts or blooms can be bright red, orange, pink, even salmon.
Anthurium is an upright many-stemmed plant that can grow 20 to 36 inches (50-91cm) tall. The lacquered-looking, puckered blooms of flamingo flowers make this plant look artificial. Each flower can last for 2 to 3 months.
Anthurium is an erect, leafy plant with pencil-shaped stalks and heart-shaped or tapering leaves up to 18 inches (45cm) long.

- Anthurium does not appreciate cold temperatures or hard water. Keep the temperature at least 60°F (16°C).
- Remove yellowing and spent blooms.
Growing Anthurium as a Houseplant
- Anthurium must have limited light, average to warm temperatures, and high humidity.
- If the humidity is too low, Anthurium will not flower.
- The potting mix should be kept evenly moist.
- Mature plants can be fed regularly in spring and summer.
- If aerial roots develop, cover them with moist sphagnum peat moss.
Anthurium Pests and Diseases

Anthurium Frequently Asked Question
Q: How can I get my Anthurium to bloom?
A: Anthuriums are tropical and demand high humidity and heat while in active growth and then cooler conditions while in flower. The flowering season stretches from spring to late summer. Anthurium needs a minimum air temperature of 60°F in winter. The pot must be well drained and sphagnum, peat moss, fibrous loam, and sand are the best potting medium. The crown must be above the soil, and the stem base and aerial roots should be wrapped with moss. Mist Anthurium frequently. If you succeed in flowering it, you are a true artist.
Q: If Anthuriums are difficult to grow, can you recommend where to start?
A: The most popular Anthurium variety is Anthurium scherzerianum. It is the most tolerant of ordinary room conditions. This is the one to choose. It grows about 1 foot high and is brilliant red, but there is a white variety (album).
Q: How can I grow Anthurium successfully?
A: Keep Anthurium warm, not cooler than 60°F but 10 degrees warmer is best. Make sure the soil is well drained. Give a little water every few days to keep the compost moist at all times. Mist the leaves frequently. Repot the plant in spring every two years and divide the plant at repotting time.
