Anthurium

Scientific name: Anthurium x (various)
Synonyms: Flamingo Flower

Also called the Flaming Flower, the Anthurium is a popular indoor plant due to its ease of care. These houseplants produce beautiful, long-lasting flowers throughout the year. The waxy heart-shaped ‘flowers’ are actually modified leaves. Anthurium ‘flowers’ come in red, pink, pale yellow, white and salmon. As the flowers die or fade, remove them from the plant immediately. 

Native to tropical rainforests throughout central and South America, many Anthuriums are climbers in their natural settings. They love warmth and humidity. Keep the leaves clean and glossy by wiping them with a damp cloth to keep them dust free.

NOTE: These plants are considered poisonous and should be kept away from pets and children.

Common Symptoms

  • Few flowers, thin straggling leaves: are a result of too little light. You may also notice that the leaves are becoming thin as the ‘stretch’ towards the light. Place your plant in an area that gets brighter or longer light hours.
  • Yellow leaf tips/Brown leaf tips: Yellow leaf tips are caused by over-watering the Anthurium, while brown leaf tips are caused by under-watering. Examine your watering schedule, light and warmth conditions and adjust accordingly.  Overwatering will also cause root rot.
  • Diseases: Fungal and bacterial plant diseases are a problem for these houseplants due to the high humidity and warmth that they love. Try to keep water off the leaves and provide the plant with good air circulation.
  • Pests: The Anthurium is susceptible to a number of pests such as the Mealy bug, Scale, Aphids and Thrip. The new tender growth is especially vulnerable. Identify the pest and treat specifically, accordingly.

Care Instructions

  • Origin: Central and South America
  • Height: up to 4 - 5m. Tall flowers may need staking to keep them upright. 
  • Light: Anthuriums like as much bright indirect light as they can get. They will tolerate almost all levels of indirect light, however, the plant will grow slower and produce fewer flowers in low light. Always keep out of direct sun. 
  • Water: Water the Anthurium well and then allow the top 2-6cm of soil to dry out before watering again. 
  • Humidity: The higher the humidity, the happier the Anthurium!  
  • Temperature: Anthurium plants prefer indoor temperatures to be warm at 22-28 °C and about 10 degrees cooler at night. 
  • Soil: Use a rich potting soil that contains some mulch and sphagnum moss. The soil needs to be fast-draining.
  • Fertilizer: Use a balanced fertilizer diluted by 1/3-1/4 and feed the plant monthly during the spring and summer when the plant is actively growing.
  • Resting period: Give your plant a 6-week resting period during the winter. During this time let your plant sit in lower temperatures, less light and drier soil to encourage your plant to produce more flowers in the spring and summer months. 
  • Repotting: Repot annually as needed. The Anthurium plant doesn’t mind being a little root bound, so only repot if necessary. Repot in spring and choose a pot that is one size or about 5cm bigger. Set the plant high so the crown of the plant sits above the soil line.
  • Pruning: Prune faded or dead flowers as soon as they appear.  
  • Propagation: Division: Divide crowded clumps when re-potting the plant. New plants should bloom in about a year.
