Lace Fern vs Mallow Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
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.
Mallow
Malva sylvestris
Malva sylvestris, or Common Mallow, is a herbaceous annual, biennial, or perennial plant known for its attractive, often purple-veined, pink to mauve flowers. It typically grows to a height of 2-4 feet. While primarily an outdoor plant, it is sometimes grown indoors, though it requires very bright light and ample space. People grow it for its ornamental value, edible leaves and flowers, and medicinal properties. It's a common sight in gardens, roadsides, and disturbed areas.

💡 Pro Tips For Comparing These Plants
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.
Mallow Care Tips
Common Mallow is primarily an outdoor plant and requires very bright light to thrive indoors. It needs well-draining soil and regular watering. Indoor cultivation is challenging due to its high light requirements and potential for pest infestations. Consistent monitoring is essential.
- Provide at least 6 hours of direct sunlight daily for optimal growth and flowering.
- Ensure well-draining soil to prevent root rot.
- Water deeply but infrequently, allowing the soil to dry slightly between waterings.
- Fertilize monthly during the growing season with a balanced liquid fertilizer.
- Protect from frost in winter by mulching around the base of the plant.

❓ Frequently Asked Questions — Comparing These Plants
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.
Mallow
What are the light requirements for Mallow?
Mallow plants thrive in full sun, requiring at least 6 hours of direct sunlight each day to promote abundant blooming. Insufficient light can lead to leggy growth and reduced flower production. An east-facing or south-facing window is ideal for indoor Mallows. If natural light is limited, supplement with a grow light. Rotate the plant regularly to ensure even light exposure on all sides. Avoid placing Mallows in excessively shady locations, as this can weaken the plant and make it more susceptible to pests and diseases. When transitioning Mallows from indoors to outdoors, gradually acclimate them to the increased sunlight to prevent leaf burn.
How do I care for Mallow?
Mallow plants require well-draining soil and should be watered when the top inch of soil feels dry. Provide them with at least 6 hours of sunlight daily for optimal blooming. Fertilize regularly during the growing season with a balanced fertilizer, switching to a bloom-boosting formula as flowering begins. Deadhead spent flowers to encourage continuous blooming. Mallows prefer moderate humidity levels; increase humidity if needed by using a humidifier or placing the plant on a pebble tray. Prune regularly to maintain shape and remove any dead or diseased growth. Protect from frost in colder climates, either by moving potted plants indoors or providing adequate insulation. Monitor for pests and diseases and treat promptly. Repot when the plant becomes root-bound.
How do I propagate Mallow?
Mallow can be propagated through division, stem cuttings, and seed.
