Anthurium (available in multiple colors)
Popular in tropical flower arrangements, Anthurium bouquets are often used in weddings on Hawaii and other Pacific islands. Anthurium flowers are long-lasting, and newer cultivars will bloom almost year-round. The glossy colored, heart-shaped flowers are actually spathes that last for several weeks, each with a white spadix covered densely with its tiny, true flowers. Long, dark-green leathery leaves grow up to 8-in (20 cm) long, held on upright stems.
Anthurium leaves are poisonous. They contain calcium oxalate crystals that cause severe burning in the mouth. Keep the plant away from pets who may play with or chew on its foliage. It's also a good idea to wear gloves when handling this plant to avoid skin irritation. It is a perennial that will live for several years with good care.
Height: Up to 18 in (45 cm); compact cultivars reach only 12 in (30 cm). Tall flower stems may need staking.
Light: Bright light will make these beauties bloom. Give your plant as much bright light as you can year-round (at least 4 hours of bright light each day), but keep it out of direct sun. A curtain-filtered sunny window is ideal.
Water: Keep soil evenly moist spring through fall, slightly drier in winter. Yellow leaves are often caused by overwatering. Water thoroughly, but don't allow soil to get soggy.
Humidity: This South American rain forest native craves high humidity year-round. Try to maintain 50% relative humidity or higher.
Temperature: (65-80°F/18-27°C) Anthurium plant prefers steady warm temps, just like we do. Protect it from cold blasts from doorways, windows and A/C vents.
Soil: Peat moss based potting mix with added perlite for good drainage; African violet potting mix is ideal.
Fertilizer: Feed every 2 weeks in spring and summer with a high-phosphorus water-soluble fertilizer.
Propagation: Divide crowded clumps when repotting. When a plant grows a new crown near the main plant, gently pull it away and plant it separately in a small container, keeping the crown of the plant above the soil line. New plants should bloom in about a year.
