Rainbow Fern vs Windflower Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
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.
Windflower
Anemone spp.
Windflowers, belonging to the genus Anemone, are herbaceous perennials known for their delicate, cup-shaped flowers. They range in height from 6 inches to 2 feet, depending on the species. The flowers come in a variety of colors, including white, pink, red, purple, and blue. Many species have rhizomatous roots, allowing them to spread. They are primarily grown outdoors in gardens and borders for their attractive blooms, which appear in spring, summer, or fall, depending on the species. Attempting to grow them indoors is challenging due to their need for specific temperature fluctuations and dormancy periods.

❓ Frequently Asked Questions — Comparing These Plants
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.
Windflower
What are the light requirements for Windflower?
Windflowers prefer partial shade, particularly during the hottest part of the day. Direct sunlight can scorch their delicate leaves and fade their vibrant blooms. An east-facing window or a spot with filtered sunlight is ideal for indoor Windflowers. If growing outdoors, plant them under the dappled shade of trees or shrubs. Insufficient light can result in leggy growth and reduced flowering. Monitor the leaves for signs of scorching or fading, and adjust the plant’s location accordingly. Rotate potted plants regularly to ensure even light exposure on all sides.
How do I care for Windflower?
Windflowers thrive in well-draining soil and prefer partial shade, especially in warmer climates. Water regularly, keeping the soil consistently moist but not waterlogged. During the active growing season (spring and summer), fertilize every 2-4 weeks with a balanced liquid fertilizer. Deadhead spent flowers to encourage continuous blooming. Protect from strong winds and extreme temperatures. In colder regions, provide winter protection such as mulching or bringing potted plants indoors. Regularly inspect for pests and diseases. Ensure good air circulation to prevent fungal issues. Repotting is best done in the spring when new growth emerges. Provide support if needed for taller varieties.
How do I propagate Windflower?
Windflowers can be propagated through division, stem cuttings, or from seed. Division is best done in the spring or fall. Carefully dig up the plant and separate the roots into smaller clumps. Replant the clumps in well-draining soil. Stem cuttings can be taken in the spring or summer. Take a 4-6 inch cutting and remove the lower leaves. Dip the cutting in rooting hormone and plant it in a well-draining potting mix. Keep the soil consistently moist and provide bright, indirect light. Seeds can be sown indoors or outdoors. Sow seeds in well-draining soil and keep them consistently moist. Germination can take several weeks.
