By the Plantshop.com Editorial Team · Updated · How we research · Report an error

Anthuriums carry glossy, heart-shaped 'flowers' (really colored spathes) in red, pink or white for months at a time, which makes them one of the longest-blooming houseplants you can buy.

Light

Bright indirect light. Rotate the pot every few weeks so growth stays even.

Water

When the top 1-2 in of soil is dry. Always use a pot with drainage holes and empty the saucer after watering. Plants use far less water in winter.

Humidity and temperature

Humidity: medium to high. Most houseplants prefer 60-80°F (16-27°C) and dislike cold drafts and heating vents.

Soil and feeding

Use a well-draining potting mix with bark or perlite for air. Feed lightly in spring and summer with a balanced houseplant fertilizer at half strength; skip feeding in winter.

Our tip

More light means more blooms. A bright spot out of harsh midday sun keeps it flowering year-round.

Common problems

Pets

Toxic to cats and dogs (ASPCA), according to the ASPCA plant list. If a pet chews it and shows symptoms, call your vet or the ASPCA Animal Poison Control Center. Check any plant in our Pet-Safe Plant Checker.
