Paper Plant vs Rainbow Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Paper Plant
Tetrapanax papyrifer
Tetrapanax papyrifer, the Paper Plant, is a large, fast-growing shrub or small tree typically grown outdoors. It features enormous, deeply lobed palmate leaves that can reach up to 3 feet across, giving it a bold, tropical appearance. The plant produces clusters of small, creamy-white flowers in late autumn or early winter, followed by dark berries. It is primarily cultivated for its striking foliage and architectural form. While sometimes grown indoors, it requires very bright light and ample space to thrive, making it challenging for most indoor environments. The pith of the stems was historically used to make rice paper.
Rainbow Fern
Selaginella uncinata
Selaginella uncinata, commonly known as Rainbow Fern, is a creeping, mat-forming plant prized for its iridescent blue-green foliage. The shimmering effect is caused by the reflection of light off the leaf surfaces. It is not a true fern, but a spikemoss. While it can be grown indoors, it requires very high humidity and consistent moisture, making it a challenging houseplant. People grow it for its unique coloration and texture, adding a touch of the exotic to terrariums or humid environments.

💧 Watering Needs
Paper Plant
Water thoroughly when the top inch of soil is dry during the growing season. Reduce watering in winter. Overwatering can lead to root rot, especially indoors. Underwatering will cause leaves to droop and brown.
Rainbow Fern
Keep the soil consistently moist but not soggy. Water when the top of the soil feels slightly dry to the touch. Overwatering can lead to root rot, while underwatering will cause the fronds to dry out and turn brown. Use distilled or rainwater to avoid mineral buildup.

❓ Frequently Asked Questions — Comparing These Plants
Paper Plant
What are the light requirements for Paper Plant?
Paper Plant needs bright, indirect light to thrive. Insufficient light can lead to leggy growth and pale foliage. While it can tolerate some direct morning sun, avoid intense afternoon sun, which can scorch the leaves. A location near an east-facing window is ideal. If using artificial lighting, provide 12-14 hours of light per day with a full-spectrum grow light. Rotate the plant regularly to ensure even light exposure on all sides. If the plant is in a pond, ensure it receives adequate sunlight but is also partially shaded during the hottest part of the day.
How do I care for Paper Plant?
Paper Plant thrives in consistently moist to wet conditions. Ideally, keep the base of the plant submerged in water or in very wet soil. Provide bright, indirect light for optimal growth. Direct sunlight can scorch the leaves. Maintain a water temperature between 65-80°F (18-27°C). Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength, specific for aquatic plants. Prune regularly to remove any dead or yellowing foliage. Repot annually in spring to refresh the growing medium. Monitor for pests like aphids or spider mites, and treat promptly if detected. Ensure good water circulation to prevent algae growth and maintain water clarity.
How do I propagate Paper Plant?
Paper Plant can be easily propagated through division or cuttings.
Rainbow Fern
What are the light requirements for Rainbow Fern?
Rainbow Fern requires bright, indirect light to maintain its vibrant coloration. Direct sunlight can scorch its delicate fronds, so avoid placing it in direct sun exposure. An east-facing window is often ideal, providing gentle morning light. A north-facing window can also work, but supplemental lighting might be necessary if the plant doesn’t receive enough natural light. If placed near a south or west-facing window, use a sheer curtain to filter the light. Insufficient light can cause the colors to fade and the plant to become leggy. Observe the plant’s response to light and adjust its placement accordingly.
How do I care for Rainbow Fern?
Rainbow Fern thrives in bright, indirect light and consistently moist soil. Water thoroughly when the top inch of soil feels slightly dry, using distilled or filtered water to avoid mineral buildup. Maintain high humidity levels, ideally above 70%, through regular misting, a humidifier, or a pebble tray. Plant in a well-draining, acidic potting mix. Fertilize lightly during the growing season (spring and summer) with a diluted liquid fertilizer. Avoid direct sunlight, which can scorch the delicate foliage. Maintain temperatures between 60-75°F (15-24°C). Prune any dead or damaged fronds to encourage new growth. Ensure good air circulation to prevent fungal diseases. Repot only when necessary, usually every 1-2 years, using a slightly larger pot.
How do I propagate Rainbow Fern?
Rainbow Fern can be propagated by division or spores.
