Anthuriums are stunning houseplants known for their vibrant, heart-shaped blooms and lush green foliage. These tropical plants are native to warmer regions, which may lead one to ask, can anthuriums survive winter? The answer, to an extent, lies in the proper care and attention given to the plant during these colder months.

The minimum temperature that anthurium plants can tolerate is 60 degrees Fahrenheit (15.5 degrees Celsius). Anything below this level can cause the anthurium to wilt and possibly suffer damage. In areas experiencing freezing temperatures, it is advised not to grow anthuriums outdoors year-round. However, it is possible to relocate them to a warmer spot like your garden, patio, or balcony during the summer.

While anthuriums can cope with cold temperatures if provided proper care, maintaining consistent warmth, humidity, and indirect sunlight remains crucial to ensuring your anthurium thrives through the winter months. A little extra attention will help your plant stay strong and beautiful, even when the weather outside turns chilly.

Anthurium Plant Overview


Anthurium plants are known for their beautiful, heart-shaped leaves and bright, long-lasting flowers. They come in various colors, such as red, pink, and white. A popular tropical indoor plant, Anthuriums provide a touch of elegance and beauty to any home.

These plants are also air purifiers, and they help to remove harmful pollutants from the air. They are relatively low-maintenance, making them ideal for both beginner and experienced gardeners. It is crucial to be aware of their specific needs to ensure they grow healthy and vibrant.

Temperature Requirements

Anthuriums thrive in temperatures between 60 and 90 degrees Fahrenheit. They prefer a warm environment and do not tolerate cold or freezing temperatures well. In fact, even a light frost could cause significant damage to these delicate plants. If you live in an area where winters can get harsh, it’s essential to consider the specific conditions under which Anthuriums can grow.

During colder months, ensure that your Anthurium is protected from cold drafts and fluctuating temperatures. Providing a stable environment with consistent temperatures will help your plant to stay healthy and robust throughout the winter. Position your Anthurium in a well-lit area with bright, indirect light, as insufficient light may prevent them from producing flowers during their growing season.

In summary, though Anthuriums can survive winter, they require appropriate care and attention to maintain their health and beauty. Keeping an eye on temperature requirements and providing your plant with proper light and humidity levels will ensure that your Anthurium thrives indoors all year round, bringing a vibrant touch of the tropics to your space.

Winter Care for Anthurium

Ideal Indoor Conditions

To help anthuriums survive winter, it’s essential to provide them with optimal indoor conditions. The ideal temperature range for anthuriums is between 60°F and 90°F (16°C to 32°C). Anthuriums prefer humidity levels of at least 80%, so consider using a humidifier or placing the plant in a bathroom, where there’s more moisture in the air. Be wary of exposing your anthurium to wind, drafts, and heaters, as these can negatively affect its environment and cause damage.

During the winter months, anthuriums will benefit from a six-week rest period. Ensure to lower temperatures, reduce light exposure, and let the soil dry out a bit to help the plant produce more flowers in the spring and summer (Bloomscape).

Outdoor Protection Methods

If you live in a region with mild winters, you might be able to grow your anthurium outdoors with some protection. Cover your anthuriums with frost cloths or move them to a sheltered area to avoid temperature fluctuations. Keep in mind, however, that temperatures below 50°F (10°C) can potentially damage the leaves and stems of your anthurium, causing them to become brown and droopy (Plantophiles).

During the winter, it’s essential to monitor your anthurium’s watering schedule as well. Overwatering is a common concern, so be vigilant and adjust the watering intervals as needed to maintain optimal moisture levels for your anthurium plant.

Signs of Winter Damage


During winter, anthurium plants may show signs of damage due to cold temperatures or low humidity. Some common symptoms include:

  • Drooping foliage and flowers: The plant’s leaves and blooms might start to wilt, indicating a struggle to adapt to winter conditions.
  • Brown spots or browning edges: Cold damage can cause leaves and stems to turn brown, especially when exposed to temperatures below 50°F (10°C) [^1^].
  • Stunted growth: The plant’s growth rate can significantly slow down due to lower temperatures and humidity levels.

Recovery Measures

If you notice any of the above signs of winter damage on your anthurium plant, it’s crucial to take prompt action to help it recover. Here are some steps to follow:

  1. Adjust humidity levels: For optimal health, anthurium plants require humidity levels of 80% or higher [^2^]. During winter, aim for a minimum of 50-60% humidity. You can use a humidifier or place the plant in a bathroom where there’s more moisture in the air.
  2. Maintain ideal temperatures: Anthuriums thrive in temperatures between 77-92°F (25-32°C) [^3^]. Make sure to keep your plant away from drafty windows or cold spots in your home during winter.
  3. Monitor water levels: Overwatering is a common issue when it comes to anthurium care. During winter, they require less water. Make sure to check the soil’s moisture before watering and adjust your schedule accordingly.
  4. Prune damaged areas: If you see brown or damaged leaves and stems, gently trim them off using clean pruning tools. This will help prevent the spread of disease and encourage new growth.
  5. Check for root rot: If the plant continues to struggle, it might be experiencing root rot. Carefully remove the anthurium from its pot, shake off excess soil, and inspect the roots. If you see any signs of infection, trim the affected roots and replant the anthurium in fresh soil [^4^].

By taking these recovery measures, you can help your anthurium plant survive winter and return to its healthy, vibrant state.

Preventing Winter Issues

Proper Plant Selection

Selecting the right variety of anthurium for your location is crucial in ensuring its survival during winter. Anthuriums can thrive in areas that fall within the USDA Zone 10 or higher, where the temperatures don’t usually drop below 30°F (source).
