Azalea vs Lace Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Azalea
Rhododendron spp. (including Azalea cultivars)
Azaleas are flowering shrubs known for their vibrant and abundant blooms in spring. They are typically multi-stemmed with a rounded or spreading habit. While some species are deciduous, many popular cultivars are evergreen. Azaleas are primarily outdoor plants, prized for their showy flowers that come in a wide range of colors, including pink, red, white, purple, and orange. They are often used in landscaping for foundation plantings, borders, and woodland gardens. Their relatively shallow root systems make them suitable for planting near buildings, but they require acidic soil and specific care to thrive.
Lace Fern
Nephrolepis exaltata 'Bostoniensis'
The Lace Fern, a cultivar of the Boston Fern, is prized for its delicate, finely divided fronds that create a lacy appearance. It's an evergreen perennial fern, typically grown indoors as a houseplant, although it thrives outdoors in warm, humid climates. Its arching fronds bring a lush, tropical feel to any space. People grow it for its air-purifying qualities and its ability to add texture and visual interest to indoor environments. It is not naturally an indoor plant, but adapts well with proper care.

💡 Pro Tips For Comparing These Plants
Azalea Care Tips
Azaleas are primarily outdoor plants and are challenging to grow indoors long-term. They require specific conditions like acidic soil, high humidity, and cool temperatures to thrive. Indoor azaleas often suffer from poor air circulation, inadequate light, and improper watering, leading to leaf drop and failure to rebloom.
- Test your soil pH regularly and amend as needed to maintain acidity.
- Water deeply and consistently, especially during dry periods.
- Protect from intense afternoon sun to prevent leaf scorch.
- Fertilize with an acid-forming fertilizer in early spring and after flowering.
- Prune after flowering to maintain shape and remove dead or diseased branches.
Lace Fern Care Tips
Lace Ferns require consistent moisture, high humidity, and bright, indirect light. Maintaining adequate humidity is crucial for preventing brown, crispy fronds. They are not particularly difficult, but require more attention than some other houseplants.
- Mist the fronds regularly to increase humidity.
- Use a humidifier if the air is dry.
- Water thoroughly when the top inch of soil feels dry.
- Avoid placing the plant in direct sunlight.
- Fertilize regularly during the growing season.

❓ Frequently Asked Questions — Comparing These Plants
Azalea
What are the light requirements for Azalea?
Azaleas thrive in bright, indirect light. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch their delicate leaves and fade their blooms. An east-facing window is ideal, providing gentle morning sun. A north-facing window can also work, but the light may be less intense. If you’re growing azaleas indoors, supplement with artificial light if necessary, especially during the winter months. Insufficient light can lead to leggy growth and reduced blooming. When placing azaleas outdoors, choose a location with dappled shade, such as under a tree canopy. Monitor the plant’s foliage for signs of sunburn, such as brown spots or bleached leaves, and adjust its position accordingly.
How do I care for Azalea?
Azaleas thrive in acidic, well-draining soil. Use a potting mix specifically formulated for azaleas or rhododendrons. Water thoroughly when the top inch of soil feels dry, but avoid overwatering. Ensure good drainage to prevent root rot. Azaleas prefer bright, indirect light. Avoid direct sunlight, which can scorch their leaves. Fertilize in early spring with an acid-loving fertilizer. Prune after flowering to maintain shape and remove dead or diseased branches. Maintain humidity by misting regularly or placing the plant on a pebble tray filled with water. Protect from frost and extreme temperatures. Repot every 2-3 years as needed, using a slightly larger pot. Watch for pests such as aphids and spider mites, and treat accordingly.
How do I propagate Azalea?
Azaleas can be propagated through stem cuttings, layering, or division. For stem cuttings, take 4-6 inch cuttings from new growth in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a moist mixture of peat moss and perlite. Cover with a plastic bag to maintain humidity and place in a warm, bright location. Roots should develop in 6-8 weeks. For layering, bend a low-lying branch to the ground and bury a portion of it in soil. Once roots develop, sever the branch from the parent plant. Division can be done in early spring or fall. Carefully dig up the plant and separate the root ball into smaller sections. Replant each section in a separate pot. Water well.
Lace Fern
What are the light requirements for Lace Fern?
Lace Ferns require bright, indirect light to thrive. Direct sunlight can burn their delicate fronds, causing them to turn brown and crispy. An east-facing window is often ideal, providing gentle morning sun. A north-facing window can also work, but be sure the fern receives sufficient ambient light. If your Lace Fern is placed in a location with less natural light, consider supplementing with a grow light. Avoid placing the fern near south- or west-facing windows without a sheer curtain to filter the harsh sunlight. Rotate the plant regularly to ensure even light exposure and prevent it from leaning towards the light source. Observe the fronds for signs of insufficient light, such as pale green color or leggy growth.
How do I care for Lace Fern?
Lace Ferns thrive in bright, indirect light. Avoid direct sunlight, which can scorch their delicate fronds. Water regularly, keeping the soil consistently moist but not waterlogged. Use well-draining potting mix to prevent root rot. Maintain high humidity levels by misting regularly, using a humidifier, or placing the fern on a pebble tray filled with water. Fertilize monthly during the growing season (spring and summer) with a diluted liquid fertilizer formulated for ferns. Repot annually in the spring to refresh the soil and provide room for growth. Prune away any dead or yellowing fronds to encourage new growth and maintain a tidy appearance. Protect from drafts and sudden temperature changes. Monitor for pests such as spider mites and scale, and treat promptly if detected.
How do I propagate Lace Fern?
Lace Ferns can be propagated by division or spores. For division, carefully separate the rhizomes during repotting, ensuring each division has healthy roots and fronds. Plant each division in its own pot with well-draining potting mix. For spore propagation, collect spores from mature fronds and sow them on a sterile potting mix. Cover with a plastic dome to maintain high humidity. Keep the mix consistently moist and provide bright, indirect light. Spores can take several weeks to germinate, and it will be several months before you have a plant large enough to pot up. Division is the much easier and faster method.
