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.
Muhly Grass
Muhlenbergia capillaris
Pink Muhly Grass is a warm-season perennial grass prized for its airy, pinkish-red flower plumes that appear in the fall. It forms an upright, rounded clump of fine-textured, green foliage. Typically grown outdoors in gardens and landscapes for its ornamental value, it provides beautiful texture and color. It is not naturally an indoor plant and will likely struggle to thrive indoors due to insufficient light and humidity. People grow it for its stunning fall display and low-maintenance nature.

❓ 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.
Muhly Grass
What are the light requirements for Muhly Grass?
Muhly Grass demands ample sunlight to flourish and produce its signature blooms. Aim for at least six hours of direct sunlight each day. A location with full sun exposure will ensure vibrant flower production and prevent the plant from becoming leggy. If grown in partial shade, the grass may still survive, but the flowering will be significantly reduced, and the plant will be weaker overall.
How do I care for Muhly Grass?
Muhly Grass thrives in full sun, needing at least 6 hours of direct sunlight daily. Water deeply but infrequently, allowing the soil to dry out between waterings. Avoid overwatering, which can lead to root rot. Plant in well-draining soil, preferably sandy or loamy. Fertilize sparingly, using a balanced fertilizer in early spring to encourage growth and blooming. Prune back to a few inches above the ground in late winter or early spring before new growth appears.
How do I propagate Muhly Grass?
Muhly Grass is most easily propagated by division. In early spring, carefully dig up the clump and divide it into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-draining soil and water thoroughly. Keep the soil consistently moist until new growth appears.
