Helichrysum vs Lace Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Helichrysum
Helichrysum petiolare
Helichrysum petiolare, commonly known as the Licorice Plant, is a tender perennial often grown as an annual. It features soft, rounded, silvery-gray leaves that are slightly fuzzy to the touch. The plant has a trailing or mounding growth habit, making it suitable for hanging baskets, containers, and as a ground cover in warmer climates. While it can be grown indoors, it thrives outdoors in full sun. People grow it for its attractive foliage, which adds a textural element to gardens and containers. It is not typically grown for its flowers, which are small and insignificant.
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
Helichrysum Care Tips
Helichrysum petiolare is primarily an outdoor plant and requires very bright light to thrive indoors. It needs well-draining soil and careful watering to prevent root rot. Indoor cultivation can be challenging due to the high light requirements and susceptibility to pests.
- Provide at least 6 hours of direct sunlight daily for optimal growth.
- Allow the soil to dry out slightly between waterings to prevent root rot.
- Prune regularly to maintain shape and prevent legginess.
- Fertilize sparingly during the growing season.
- Monitor for pests such as spider mites and aphids and treat promptly.
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
Helichrysum
What are the light requirements for Helichrysum?
Helichrysum requires at least 6-8 hours of direct sunlight per day to thrive. Insufficient light can result in leggy growth, reduced flowering, and pale foliage. When grown indoors, place Helichrysum near a south-facing window where it can receive ample sunlight. If natural light is limited, supplement with grow lights to ensure adequate illumination.
How do I care for Helichrysum?
Helichrysum thrives in well-draining soil and requires full sun exposure for optimal growth and blooming. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain away. Avoid overwatering, which can lead to root rot. Fertilize monthly during the growing season (spring and summer) with a balanced fertilizer to promote healthy growth and abundant blooms.
How do I propagate Helichrysum?
Helichrysum can be easily propagated through stem cuttings. Take 4-6 inch cuttings from healthy stems, removing the lower leaves. Dip the cut end in rooting hormone and plant in well-draining potting mix. Keep the soil consistently moist and provide bright, indirect light. Roots should develop within 2-4 weeks.
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.
