So, let’s dive in and learn all about this captivating houseplant.

Light Requirements

Stromanthe sanguinea thrives in bright, indirect sunlight. It does best when placed near an east or north-facing window, where it can receive mild morning or dappled light. However, it is important to avoid direct sunlight, as it can lead to leaf scorching and discoloration. To ensure even growth and vibrant foliage, it is recommended to rotate the plant weekly, allowing all sides of the plant to receive adequate light.

Soil Preferences

When it comes to soil, Stromanthe sanguinea prefers a light, well-draining mix. A perlite-based potting soil or peat-based potting soil is ideal for this plant. These types of soil allow excess water to drain effectively, preventing waterlogging and root rot. Additionally, the pH level of the soil should be between 6.0 and 8.0, slightly acidic to neutral.

Watering Needs

Keeping the soil consistently moist, but not waterlogged, is key to maintaining the health of Stromanthe sanguinea. It is important to water the plant when the top inch of soil has dried out. This can be determined by gently inserting your finger into the soil to check for moisture. When watering, make sure to thoroughly saturate the soil and allow excess water to drain away. Avoid letting the plant sit in standing water, as this can lead to root rot. During the dormant season, typically in winter, water sparingly, allowing the soil to dry out slightly between waterings.

Temperature and Humidity Considerations

Stromanthe sanguinea thrives in temperatures between 65°F and 80°F (18°C – 27°C). It is important to keep the plant away from cold drafts and avoid exposure to temperatures below 60°F (15°C). The plant enjoys high humidity levels, ideally between 50% to 70%. To create a humid environment, mist the leaves regularly, especially during dry winter months. Placing the plant near a humidifier or using a humidity tray filled with water can also help increase humidity levels.


During the growing season, from spring to summer, Stromanthe sanguinea benefits from regular fertilization. Use a balanced, liquid fertilizer diluted to half strength every 2-3 weeks. This will provide the necessary nutrients for healthy growth. However, it is important to avoid fertilizing during the winter season when the plant is dormant.

Growth Habits

Stromanthe sanguinea is a slow-growing plant that can reach a height of 2 to 3 feet (0.6 – 0.9 meters) with foliage spanning up to 2 feet (0.6 meters) in width. While it can produce flowers, it is rare for Stromanthe sanguinea to do so when kept indoors. The plant experiences a dormancy period in winter, during which it may enter a state of rest and requires less frequent watering.


Choosing the right pot for Stromanthe sanguinea is crucial for its growth and overall health. Select a pot with drainage holes to allow excess water to escape. The pot should be large enough for the plant’s roots to spread comfortably. When repotting, it is best to do so during the spring to summer months when the plant is actively growing. Repotting annually is usually not necessary, as Stromanthe sanguinea prefers to be slightly rootbound.


Pruning is an essential part of Stromanthe sanguinea’s care routine. Regularly inspect the plant for damaged or discolored leaves and remove them at the base using clean kitchen knives or garden shears. It is important not to remove more than 30% of the foliage at a time to avoid excessive stress on the plant. Pruning also helps maintain the plant’s shape and allows new growth to flourish.

Propagation Methods

Stromanthe sanguinea can be propagated through the division of its rhizomes. To propagate, carefully separate the rhizomes before new growth starts in the spring. Each division should have two to three leaves attached. Plant the divisions in separate pots filled with a well-draining potting mix, and keep them in a warm and humid environment. With proper care, the divisions will develop their roots and grow into new plants.

Common Problems

Like any other houseplant, Stromanthe sanguinea may experience a few common issues. Fungal diseases, root rot, mealybugs, spider mites, and aphids are among the potential problems. Regularly inspect your plant for any signs of pests or diseases. If detected, treat them promptly with appropriate insecticides or natural remedies. Ensure the plant’s environment remains clean, avoid overwatering, and provide proper air circulation to prevent issues such as root rot or fungal diseases.


Stromanthe sanguinea, with its vibrant foliage and unique coloration, is a fantastic addition to any indoor plant collection. By understanding its light requirements, soil preferences, watering needs, temperature and humidity considerations, fertilization, growth habits, potting, pruning, propagation methods, and common problems, you can provide the optimal care for this stunning plant. Remember to place it in bright, indirect light, maintain a moist but well-draining soil, water when the top inch of soil has dried, provide sufficient humidity, fertilize during the growing season, and address any potential issues promptly. With these care tips in mind, your Stromanthe sanguinea will thrive and bring beauty to your home or office space.
