Magnolia vs Rainbow Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Magnolia
Magnolia spp.
Magnolias are a diverse genus of flowering trees and shrubs known for their large, showy flowers, which can be white, pink, purple, or yellow. They range in size from small shrubs to large trees, with deciduous and evergreen species. Magnolias are primarily outdoor plants, valued for their ornamental beauty and fragrant blooms. Their leaves are typically large, oval, and leathery. While some smaller varieties might be temporarily kept indoors, they generally require outdoor conditions to thrive.
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
Magnolia
Water deeply and regularly, especially during the first few years after planting. Established trees are relatively drought-tolerant but benefit from supplemental watering during dry periods. Overwatering can lead to root rot, indicated by yellowing leaves and stunted growth. Underwatering results in wilting and leaf drop.
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.

💡 Pro Tips For Comparing These Plants
Magnolia Care Tips
Magnolias are primarily outdoor trees and shrubs that require full sun, well-drained soil, and regular watering. They are not suitable for long-term indoor cultivation due to their size, light requirements, and dormancy needs. Indoor attempts will likely result in a weakened, non-flowering plant.
- Choose a magnolia variety that is well-suited to your climate.
- Plant in well-draining soil amended with organic matter.
- Water deeply and regularly, especially during the first few years.
- Fertilize in early spring with a balanced slow-release fertilizer.
- Protect young trees from frost in winter.
Rainbow Fern Care Tips
Rainbow Ferns are challenging houseplants due to their high humidity and moisture requirements. They thrive in terrariums or enclosed environments where humidity can be maintained. Consistent watering and bright, indirect light are crucial for their survival indoors. It is primarily an outdoor plant in tropical climates.
- Use distilled or rainwater to avoid mineral buildup on the fronds.
- Maintain high humidity by misting regularly or using a humidifier.
- Provide bright, indirect light to enhance the iridescent coloration.

❓ Frequently Asked Questions — Comparing These Plants
Magnolia
What are the light requirements for Magnolia?
Indoor Magnolias thrive in bright, indirect light. An east-facing window is often ideal, providing gentle morning sun. A south-facing window can also work, but be sure to filter the light with a sheer curtain to prevent leaf scorch. A west-facing window can provide intense afternoon light, which might be too strong, so monitor the plant carefully. Insufficient light can lead to leggy growth, reduced flowering, and overall weakened health. Rotate the plant regularly to ensure all sides receive adequate light. If natural light is limited, consider using a grow light to supplement. Position the grow light 12-18 inches above the plant and provide 12-14 hours of light per day.
How do I care for Magnolia?
Indoor Magnolia trees need bright, indirect light. Direct sunlight can scorch the leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Use a well-draining potting mix formulated for acid-loving plants. Maintain humidity levels around 50-60% by misting regularly or using a humidifier. Fertilize during the growing season (spring and summer) with a balanced, slow-release fertilizer formulated for acid-loving plants. Prune lightly in late winter or early spring to remove dead or crossing branches and to maintain shape. Repot every 2-3 years, or when the plant becomes root-bound, into a slightly larger pot. Protect from drafts and sudden temperature changes. Monitor for pests such as spider mites or aphids and treat promptly. Rotate the plant regularly to ensure even growth. Provide stable conditions and avoid moving the plant frequently, as Magnolias dislike being disturbed.
How do I propagate Magnolia?
Magnolias can be propagated through stem cuttings or air layering. For stem cuttings, take 4-6 inch semi-hardwood cuttings in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist and humid. Rooting can take several weeks. For air layering, make a small incision on a branch and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Keep the moss moist. Roots should form within a few months. Once roots are visible, cut the branch below the rooted area and plant it in a pot. Ensure stable conditions.
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.
