Fig Tree vs Rainbow Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Fig Tree
Ficus carica
Ficus carica, the common fig, is a deciduous tree or large shrub known for its edible fruit. Typically growing to 3-10 meters tall, it features a spreading habit and distinctive lobed leaves. While primarily an outdoor plant, it can be grown indoors with significant effort. People cultivate fig trees for their sweet, nutritious fruits, which can be eaten fresh, dried, or processed into jams and preserves. Indoor cultivation is challenging due to the plant's high light requirements and dormancy needs.
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.

🔬 Botanical Information — Comparing These Plants
Fig Tree
| Scientific Name | Ficus carica |
|---|---|
| Family | Moraceae |
| Native To | Western Asia and the Middle East |
| Also Known As | Common Fig, Edible Fig |
| Leaves | The leaves are large, deeply lobed, and rough in texture. They are typically a vibrant green color. Leaf size can vary depending on the variety and growing conditions, but generally range from 10-20 cm in length. |
| Flowers | Fig trees rarely flower indoors. The flowers are inside the fruit (syconium) and are not visible. |
Rainbow Fern
| Scientific Name | Selaginella uncinata |
|---|---|
| Family | Selaginellaceae |
| Native To | China |
| Also Known As | Rainbow Fern, Peacock Fern, Blue Fern, Spikemoss |
| Leaves | Small, scale-like leaves arranged in overlapping rows along the stems. The leaves are typically a vibrant blue-green color with an iridescent sheen. They are delicate and finely textured. |
| Flowers | Selaginella uncinata does not produce flowers in the typical sense. It reproduces via spores, which are produced in strobili (cone-like structures) at the tips of the stems. These are rarely seen indoors. |

💧 Watering Needs
Fig Tree
Water thoroughly when the top inch of soil is dry. Allow excess water to drain away. Overwatering can lead to root rot, indicated by yellowing leaves and a musty smell. 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.

❓ Frequently Asked Questions — Comparing These Plants
Fig Tree
What are the light requirements for Fig Tree?
Fig trees need bright, indirect light to thrive. Direct sunlight can scorch their leaves, especially during the hottest part of the day. An east-facing window is often ideal, providing gentle morning light. A south- or west-facing window can also work, but be sure to filter the light with a sheer curtain.
How do I care for Fig Tree?
Fig trees thrive in bright, indirect light. Water thoroughly when the top inch of soil feels dry to the touch, but avoid overwatering, which can lead to root rot. Ensure the pot has good drainage. Maintain a consistent temperature between 65-75°F (18-24°C). Fig trees prefer moderate to high humidity. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.
How do I propagate Fig Tree?
Fig trees can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. 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. Roots should develop in a few weeks.
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.
