Indian Shot vs Rainbow Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Indian Shot
Canna indica
Canna indica, commonly known as Indian Shot, is a rhizomatous perennial known for its bold foliage and vibrant flowers. It typically grows to a height of 1-2 meters. The plant features large, paddle-shaped leaves and produces asymmetrical flowers in shades of red, orange, yellow, or pink. While it can be grown indoors, it requires very bright light and ample space, making it primarily an outdoor plant. People grow it for its ornamental value, adding a tropical flair to gardens and landscapes. The rhizomes are also edible, providing starch.
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
Indian Shot
Water deeply when the top inch of soil feels dry. Avoid overwatering, which can lead to rhizome rot. During the growing season, water more frequently. Reduce watering in the winter. Signs of underwatering include drooping leaves and dry soil. Overwatering signs include yellowing leaves and soggy soil.
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
Indian Shot Care Tips
Canna indica is primarily an outdoor plant. Growing it indoors is challenging due to its high light requirements and potential for aggressive rhizome spread. It needs very bright light, consistent moisture, and regular fertilization. Overwintering rhizomes indoors is a common practice in colder climates.
- Provide consistent moisture during the growing season.
- Fertilize regularly to promote flowering.
- Protect from strong winds that can damage the large leaves.
- Overwinter rhizomes indoors in cold climates.
- Divide rhizomes every few years to prevent overcrowding.
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.

❓ Frequently Asked Questions — Comparing These Plants
Indian Shot
What are the light requirements for Indian Shot?
Indian Shot plants thrive in bright, sunny locations. Ideally, they need at least 6 hours of direct sunlight each day to produce abundant blooms. While they can tolerate partial shade, insufficient light can result in fewer flowers and leggy growth. The intensity of sunlight influences the flower color; brighter light often leads to more vibrant hues.
How do I care for Indian Shot?
Indian Shot thrives in warm conditions and requires well-draining soil. Plant rhizomes in the spring after the last frost, about 4-6 inches deep and 1-2 feet apart. Choose a location with full sun to partial shade; at least 6 hours of direct sunlight is optimal for flowering. Water deeply and regularly, especially during hot, dry periods, keeping the soil consistently moist but not waterlogged.
How do I propagate Indian Shot?
Indian Shot can be easily propagated through division of the rhizomes. In early spring, before new growth begins, carefully dig up the plant and separate the rhizomes into sections, ensuring each section has at least one growth eye. Plant the divisions in well-draining soil, about 4-6 inches deep, and water thoroughly.
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.
