Introduction
Button fern, also known as round-leafed fern or cliff brake, is scientifically named Hemionitis rotundifolia (formerly Pellaea rotundifolia). It is a small, evergreen fern with rounded, leathery leaves that thrive in indoor environments. This compact and low-maintenance plant is well-suited for homes, adding a touch of greenery with its delicate, arching fronds. Its resilience and unique appearance make it a popular choice for houseplant enthusiasts.
Exploring 4 Varieties of Button Fern Plants
Button fern plants, particularly the species Hemionitis rotundifolia (formerly Pellaea rotundifolia), are known for their small, rounded leaves. While the classic button fern is the most common variety, here are some other varieties and related species that are often grouped under the “button fern” category due to their similar appearance and characteristics:
Pellaea rotundifolia (classic button fern): Known for its small, dark green, rounded leaflets and compact growth habit.
Pellaea falcata (Sickle fern): While not a true button fern, this variety has sickle-shaped fronds with a similar care routine.
Pellaea atropurpurea (Purple-stemmed cliff brake): Features dark purple stems and delicate, rounded leaflets, adding a unique contrast to the typical green fronds.
Pellaea viridis: Has a slightly larger and more elongated leaf structure compared to the classic button fern, but still retains a compact and delicate appearance.
These varieties share common traits like low-maintenance care, tolerance for lower light conditions, and preference for well-drained soils. They are all popular choices for adding a lush, fern-like texture to indoor gardens.
How to Grow and Care for Button Fern Plant
Growing and caring for a Button Fern (Hemionitis rotundifolia) is relatively easy. Here’s a guide to help your plant thrive:
1. Light Requirements
- Bright, indirect light: Button ferns prefer bright but indirect light. Too much direct sunlight can scorch the leaves, while too little light may stunt growth. A spot near a north or east-facing window is ideal.
- Tolerates lower light: It can survive in low-light conditions but may grow more slowly.
2. Soil
- Well-draining soil: Use a peat-based potting mix with good drainage. A mixture of potting soil, perlite, and some sand works well.
- Slightly acidic: These plants prefer slightly acidic to neutral pH levels in the soil.
3. Watering
- Consistent moisture: Keep the soil consistently moist but not soggy. Water when the top inch of soil feels dry. Avoid letting the soil dry out completely.
- Humidity: Button ferns love humidity, so mist the leaves regularly, especially in dry climates or during the winter months.
4. Temperature
- Moderate temperatures: Ideal temperatures range between 60–75°F (16–24°C). Avoid exposing the plant to cold drafts or temperatures below 50°F (10°C).
5. Fertilizer
- Light feeding: Fertilize with a balanced, diluted liquid fertilizer once a month during the growing season (spring and summer). Avoid over-fertilizing, as ferns are sensitive to excess nutrients.
6. Pruning
- Trim dead fronds: Remove any dead or yellowing fronds to keep the plant healthy and promote new growth.
7. Repotting
- Repot when root-bound: Button ferns don’t need frequent repotting, but when the roots start to outgrow the pot, move the plant to a slightly larger container. Repot every 1-2 years if needed.
8. Pests and Diseases
- Watch for pests: Button ferns are generally pest-resistant but can occasionally attract aphids or spider mites. Use insecticidal soap or neem oil to treat infestations.
- Avoid overwatering: Too much water can lead to root rot or fungal issues.
9. Propagation
- Division method: Button ferns are best propagated by division. In spring, gently divide the root ball into smaller sections and replant them in separate pots.
By providing the right balance of light, moisture, and humidity, your Button Fern will remain lush and healthy, making a charming addition to any indoor space.
10 Steps for Propagating Button Fern Plant
Propagating a Button Fern (Hemionitis rotundifolia) is best done through division. Here are the steps for successfully propagating this plant:
1. Choose the Right Time
- The best time to propagate a Button Fern is in the spring when the plant is actively growing. This ensures better recovery and growth after division.
2. Prepare the Tools
- You’ll need a clean, sharp knife or scissors, fresh potting mix, and new pots for planting the divided sections.
3. Water the Plant
- Water the Button Fern thoroughly a day before propagation. This softens the roots and makes it easier to divide the plant.
4. Remove the Plant from the Pot
- Gently remove the plant from its pot by tipping it upside down while supporting the base of the fronds. If the roots are stuck, gently loosen them by tapping the sides or squeezing the pot.
5. Divide the Root Ball
- Once the plant is out of the pot, inspect the root ball. Look for natural clumps or sections where the fern can be divided. Using your hands or a sharp knife, carefully separate the plant into 2-3 smaller sections, making sure each section has some healthy roots and fronds.
6. Prepare New Pots
- Fill the new pots with a well-draining, peat-based potting mix. Ensure the soil is slightly moist but not soggy.
7. Plant the Divisions
- Place each divided section into a new pot. Bury the roots in the soil, making sure the base of the fronds sits just above the soil line.
8. Water and Place in Indirect Light
- Water the newly potted divisions thoroughly but allow excess water to drain. Place the pots in a location with bright, indirect light to help them establish.
9. Maintain Humidity
- Keep the humidity levels high by misting the plants regularly or placing a humidity tray under the pots. This helps reduce transplant shock.
10. Monitor Growth
- Over the next few weeks, monitor the plants for new growth, which indicates successful propagation. Keep the soil moist but avoid overwatering.
By following these steps, you’ll be able to propagate and grow new Button Ferns successfully!

Common Problems
Button Ferns (Hemionitis rotundifolia) are relatively easy to care for, but they can encounter some common problems if their growing conditions aren’t ideal. Here are a few common issues and how to address them:
1. Yellowing Leaves
- Cause: Overwatering or poor drainage is the most common cause.
- Solution: Ensure the soil is well-draining and that the plant isn’t sitting in water. Water only when the top inch of soil is dry. Make sure the pot has drainage holes to prevent water from accumulating.
2. Drooping or Wilting
- Cause: Underwatering or low humidity.
- Solution: Check the soil moisture and increase watering if the soil is dry. Also, raise the humidity around the plant by misting it regularly or placing it near a humidifier or a humidity tray.
3. Brown Tips or Edges
- Cause: Dry air or insufficient humidity.
- Solution: Button Ferns thrive in high humidity environments. Increase the humidity by misting the plant, using a pebble tray, or placing it in a bathroom or kitchen where humidity is naturally higher.
4. Slow or Stunted Growth
- Cause: Low light or lack of nutrients.
- Solution: Ensure the plant is receiving bright, indirect light. Feed the plant with a diluted, balanced fertilizer once a month during the growing season (spring and summer). Avoid over-fertilizing, as this can damage the fern.
5. Brown or Black Spots on Leaves
- Cause: Overwatering or fungal infections.
- Solution: Reduce watering and ensure proper air circulation around the plant. Remove affected leaves and treat with a fungicide if necessary. Avoid getting water on the leaves when watering to reduce the chance of fungal infections.
6. Leggy Growth
- Cause: Inadequate light.
- Solution: Move the plant to a brighter location with indirect light. Avoid direct sunlight, as it can scorch the delicate fronds.
7. Root Rot
- Cause: Overwatering or poor drainage.
- Solution: If the plant’s roots are mushy and the soil smells foul, root rot may be the issue. Remove the plant from its pot, trim away the affected roots, and repot it in fresh, well-draining soil. Water only when the top layer of soil dries out.
8. Leaf Drop
- Cause: Sudden environmental changes, such as a shift in temperature, humidity, or light.
- Solution: Keep the plant in a stable environment with consistent light, temperature, and humidity levels. Avoid moving the plant frequently and protect it from drafts or extreme temperature fluctuations.
By monitoring these common issues and adjusting the plant’s care routine, you can keep your Button Fern healthy and thriving.
