Moroccan Mound vs Rainbow Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Moroccan Mound
Globularia punctata
Globularia punctata, commonly known as Moroccan Mound Globularia, is a low-growing, evergreen perennial forming a dense, cushion-like mound. It typically reaches a height of 10-15 cm and spreads to about 30-45 cm. The plant features small, rounded, dark green leaves and produces spherical flower heads of pale blue or lavender in late spring to early summer. It is primarily an outdoor plant, valued for its drought tolerance and ability to thrive in rocky or sandy soils. It's grown for ground cover, rock gardens, and adding textural interest to landscapes. While technically possible to grow indoors, it requires very specific conditions and is not generally recommended.
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.

❓ Frequently Asked Questions — Comparing These Plants
Moroccan Mound
What are the light requirements for Moroccan Mound?
Moroccan Mound requires bright, indirect sunlight for optimal growth and coloration. Insufficient light can lead to etiolation, where the plant stretches and becomes leggy. An east or west-facing window is often ideal. If grown indoors, supplement with a grow light if natural light is limited, especially during winter months. Avoid placing it in direct sunlight for extended periods, as this can cause sunburn. Rotate the plant regularly to ensure even light exposure on all sides. Observe the plant’s leaves for signs of light stress, such as fading color or scorching, and adjust its placement accordingly.
How do I care for Moroccan Mound?
Moroccan Mound thrives on neglect, making it an easy-care succulent. Provide bright, indirect sunlight, avoiding harsh direct sun which can scorch leaves. Water sparingly, only when the soil is completely dry to the touch. Use a well-draining succulent mix to prevent root rot. Fertilize lightly during the growing season (spring/summer) with a balanced succulent fertilizer. Ensure good air circulation to avoid fungal issues. Repot only when necessary, when the plant becomes root-bound. Protect from frost, as it is not cold-hardy. Prune any dead or damaged leaves to maintain its appearance. Regularly check for pests, such as mealybugs or aphids, and treat promptly. This succulent prefers warm temperatures and low humidity.
How do I propagate Moroccan Mound?
Moroccan Mound can be easily propagated through leaf cuttings, offsets, or stem 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.
