Australian Tree Fern vs Coral Bells Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Australian Tree Fern
Cyathea cooperi
The Australian Tree Fern (Cyathea cooperi) is a fast-growing tree fern characterized by its elegant, arching fronds and distinctive trunk covered in brown scales. It's primarily an outdoor plant, thriving in humid, subtropical environments. Its large size and specific environmental needs make it challenging to grow indoors long-term. People grow it for its tropical appearance and architectural interest in gardens and landscapes. It can reach impressive heights in its natural habitat. The plant's beauty lies in its delicate-looking but resilient fronds.
Coral Bells
Heuchera spp.
Coral Bells (Heuchera spp.) are herbaceous perennials prized for their colorful and textured foliage. They form neat mounds of scalloped or ruffled leaves in a wide array of colors, including shades of green, purple, red, bronze, and silver. While they do produce small, bell-shaped flowers on slender stalks, the foliage is the main attraction. Primarily outdoor plants, they are popular in gardens for adding color and texture to borders, rock gardens, and woodland settings. They are grown for their ornamental foliage and relatively low-maintenance nature.

💧 Watering Needs
Australian Tree Fern
Water frequently to keep the soil consistently moist but not waterlogged. Allow the top inch of soil to slightly dry out before watering again. Overwatering can lead to root rot, while underwatering will cause the fronds to dry and brown. Ensure good drainage.
Coral Bells
Water thoroughly when the top inch of soil feels dry. Avoid overwatering, as this can lead to root rot. Ensure good drainage. Signs of overwatering include yellowing leaves and a mushy base. Underwatering results in wilting and dry, crispy leaves.

💡 Pro Tips For Comparing These Plants
Australian Tree Fern Care Tips
Australian Tree Ferns are challenging to grow indoors due to their high humidity and light requirements. They need consistent moisture and are prone to drying out in typical indoor environments. Maintaining adequate humidity is crucial for their survival. They are best suited for outdoor environments or greenhouses.
- Mist the fronds regularly to increase humidity.
- Use rainwater or distilled water to avoid mineral buildup on the fronds.
- Provide good air circulation to prevent fungal diseases.
- Protect from strong winds, which can damage the fronds.
- Fertilize regularly during the growing season with a balanced liquid fertilizer.
Coral Bells Care Tips
Coral Bells are primarily outdoor plants and can be challenging to grow indoors. They require specific light and humidity conditions that are difficult to replicate indoors. Indoor plants often suffer from poor air circulation and inconsistent watering, leading to fungal diseases. Requires very bright light and good air circulation indoors.
- Choose a cultivar that is well-suited to your local climate.
- Plant in well-draining soil to prevent root rot.
- Provide shade during the hottest part of the day to prevent leaf scorch.
- Mulch around the base of the plant to help retain moisture and suppress weeds.

❓ Frequently Asked Questions — Comparing These Plants
Australian Tree Fern
What are the light requirements for Australian Tree Fern?
Australian Tree Ferns require bright, indirect light to thrive. Direct sunlight can scorch their delicate fronds, causing them to turn brown and crispy. An east-facing window is often ideal, providing gentle morning light. A north-facing window can also work, especially if supplemented with artificial light. If you place your fern near a south or west-facing window, use a sheer curtain to filter the light.
How do I care for Australian Tree Fern?
The Australian Tree Fern thrives in consistently moist conditions and high humidity. Water thoroughly when the top inch of the soil feels slightly dry. Avoid letting the soil dry out completely, as this can lead to browning fronds. Provide bright, indirect light; direct sunlight can scorch the fronds. Maintain humidity levels above 60% by misting regularly, using a humidifier, or placing the pot on a pebble tray filled with water.
How do I propagate Australian Tree Fern?
Australian Tree Ferns can be propagated by division or spores, though spore propagation is more challenging. For division, carefully separate the trunk into sections, ensuring each section has roots. Plant each section in its own pot with well-draining soil. Keep the soil consistently moist and provide high humidity.
Coral Bells
What are the light requirements for Coral Bells?
Coral Bells thrive in partial shade, where they receive morning sun and afternoon shade. In hotter climates, full shade is preferable to prevent leaf scorch. The intensity of the leaf color can be affected by light exposure; darker-leaved varieties tend to tolerate more sun, while lighter-leaved varieties need more shade.
How do I care for Coral Bells?
Coral Bells prefer partial shade to full sun, with morning sun and afternoon shade being ideal. They thrive in well-draining soil rich in organic matter. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, which can lead to root rot. Fertilize lightly in spring with a balanced fertilizer.
How do I propagate Coral Bells?
Coral Bells can be propagated through division, stem cuttings, or keiki (small plantlets that form on the flower stalks).
