The boat lily (Tradescantia spathacea) is an attractive and easy-to-grow indoor houseplant. It is native to Central and South America. It has sword-like, pointed leaves, and its petioles hold up each supple, waxy blade. The leaves are pinkish-purple or silvery-green, depending on the light in your home. It has tiny white flowers on delicate, off-white spathes that sit atop long, thick flower stalks. The plant produces rhizomes, which can easily be separated and propagated to produce more boat lilies. It's a marvelously exotic addition to any home, and it tolerates low light and occasionally neglect.

Care Instructions:
Tradescantia spathacea, commonly known as Boat Lily or Moses-in-the-Cradle, is a popular tropical plant known for its striking foliage and unique, boat-shaped bracts that cradle small, white flowers. The leaves are green on top with a rich purple underside, making this plant a visually appealing addition to any indoor or outdoor space. Boat Lily is easy to care for and can thrive in various environments, making it a favorite among both beginner and experienced gardeners.
Light
Boat Lily thrives in bright, indirect light but can also tolerate partial shade. For the best color and growth, place it near a window where it can receive plenty of filtered sunlight, such as an east or west-facing window. While it can handle lower light conditions, the plant’s vibrant leaf colors may fade. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the leaves.
Water
Water your Boat Lily regularly, keeping the soil consistently moist but not waterlogged. During the growing season (spring and summer), water more frequently, allowing the top inch of soil to dry out between waterings. In the fall and winter, reduce watering slightly, letting the soil dry out a bit more between waterings. Be careful not to overwater, as this can lead to root rot.
Soil
Boat Lily prefers a well-draining potting mix. A standard indoor potting soil mixed with perlite or sand for drainage works well. If planting in a container, ensure it has drainage holes to prevent water from accumulating at the bottom, which can lead to root rot. The soil should be light and airy, providing enough drainage to keep the roots healthy.
Temperature
The optimal temperature range for Boat Lily is between 60°F and 85°F (16°C to 29°C). It prefers warm, stable temperatures and should be protected from cold drafts and temperatures below 50°F (10°C). While it can tolerate short periods of cooler temperatures, prolonged exposure to cold can damage the plant.
Humidity
Boat Lily enjoys moderate to high humidity levels, ideally around 50-70%. It thrives in humid environments, so if the air in your home is dry, especially during winter, consider using a humidifier, misting the plant regularly, or placing it on a humidity tray. Adequate humidity helps prevent the leaf tips from browning and keeps the foliage looking lush.
Fertilizer
Feed your Boat Lily with a balanced, water-soluble fertilizer diluted to half strength every 4-6 weeks during the growing season (spring through early fall). Regular feeding encourages healthy growth and vibrant foliage. Reduce feeding in the fall and winter when the plant’s growth naturally slows down. Over-fertilizing can lead to salt buildup in the soil, so it’s important to stick to a regular feeding schedule without overdoing it.
Best Placement Ideas
- Living Rooms: Boat Lily is ideal for living rooms, where its bold foliage can be a focal point. Place it in a bright spot with indirect light to maintain its vibrant colors and healthy growth.
- Bathrooms: Due to its preference for high humidity, Boat Lily thrives in bathrooms with natural light. The moisture from showers will help maintain the ideal humidity levels.
- Office Desks: This plant is well-suited for office environments, where it can add a touch of greenery and color to your workspace. Its low-maintenance nature makes it ideal for busy workplaces.
Common Issues
Pests: Boat Lily is generally resistant to pests but can occasionally attract spider mites, aphids, or mealybugs. Regularly inspect the leaves for any signs of pests, such as sticky residue, webbing, or small insects. Treat infestations promptly with insecticidal soap or neem oil to prevent them from spreading.
Diseases: Overwatering or poor air circulation can lead to fungal diseases, such as root rot or leaf spot. Ensure the soil is well-draining and avoid letting the plant sit in water. If you notice yellowing leaves, mushy roots, or dark spots, it may indicate a fungal issue. Improve air circulation and avoid overhead watering to help prevent these problems.
Things to Watch Out For
Watch for signs of stress, such as yellowing or browning leaves, which may indicate improper watering, low humidity, or inadequate light. If the plant’s growth slows or the leaves start to lose their vibrant color, consider adjusting its care routine to better meet its needs. Additionally, Boat Lily can become leggy if it doesn’t receive enough light, so regular pruning may be necessary to keep it looking full and healthy.
Propagation Tips
Propagation Method: Boat Lily is easily propagated through division or stem cuttings. To propagate by division, carefully separate the plant into smaller sections, each with its own root system, and replant them in fresh soil. For stem cuttings, take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and place the cutting in water or directly into moist soil. Roots should develop within a few weeks, and the new plant can then be transplanted into its own pot.
Best Time to Propagate: The best time to propagate Boat Lily is in the spring or early summer when the plant is actively growing. This timing allows the new plants to establish roots and grow during the most favorable conditions.
Maintenance Tips
Pruning: Pruning your Boat Lily involves trimming back any leggy or unruly stems to maintain its appearance and encourage bushier growth. Regular pruning helps control the plant’s size and shape and can also stimulate more vigorous growth. Use clean, sharp scissors or pruning shears to avoid damaging the plant.
Repotting: Boat Lily should be repotted every 1-2 years or when it outgrows its current container. Choose a slightly larger pot with fresh, well-draining soil. Repotting is best done in early spring before the growing season begins to give the plant time to adjust.
