Guzmania Lingulata (Scarlet Star)
Botanical Name: Guzmania lingulata
This gorgeous red tropical is one of the most common house plants from the Bromeliad family. Other popular cultivars have bright yellow or orange bracts.
New varieties of Guzmania lingulata are introduced all the time. Choose what you like -- they're all spectacular. 'Orange Star' has long-lasting orange bracts. 'Luna' is a popular variety with mauve bracts. 'Rana' is a newer hybrid with a slightly larger flower spike than the species, in orange-red.
Its leathery, glossy green leaves grow in a rosette that creates an urn which must be filled with water at all times. This is the only plant I know of that should be watered in its center and will not rot.
After 3 or 4 years, 'Scarlet Star' produces a flower head made of bright red bracts that rise in the plant's center and last about 5 months. Its small, white true flowers are almost hidden by the bracts.
Bromeliads add dazzling color and a tropical feel to any room. Get one for your office, too, and make a bold statement. It grows well under the fluorescent light of offices. Keep it out of direct sunlight to prevent the bract color from fading.
Height: About 12 in (30 cm) high. Its leaves can reach up to 18 in (45 cm) long.
Light: Put this tropical house plant in a bright location out of direct sun. Sun exposure can cause brown spots on leaves. It will thrive in the bright fluorescent light of an office.
Water: Water the center of the rosette and keep 1 in (2.5 cm) of water in its urn (center of the rosette) at all times. Bromes are sensitive to the chlorine and fluoride in tap water. Use distilled water or rainwater and allow it to warm up to room-temperature first. Houseplants hate cold water! Water soil just enough to keep the roots barely moist. Empty old water from the urn every week and promptly replace it with fresh water.
Humidity: Prefers high humidity. Try to maintain at least 50% relative humidity near your Bromeliad; the most efficient way to do this is to set your plant on a humidity tray or use a cool-mist room humidifier.
Temperature: Average to warm (65-80°F/18-27°C). Keep your plant out of cold blasts from windows and doors during the winter. Also shield it from heat/AC vents.
Soil: Bromeliad or orchid potting mix. Or mix equal parts fine-grade fir bark and all-purpose potting mix.
Fertilizer: Feed monthly spring through summer with a balanced water-soluble fertilizer diluted by half in the plant's urn, then empty it after 1 week and fill with water. Or mist the leaves with a weak foliar fertilizer once a month.
Propagation: Cut off the offsets (pups) when they reach 3 in (7.5 cm) tall and plant them in fresh, barely moist potting mix. Maintain high humidity for the pups for the first month.
