Boxwood vs Peacock Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Boxwood
Buxus spp.
Boxwood is a genus of about 70 species in the family Buxaceae. These are evergreen shrubs or small trees, reaching 1-12 meters tall. The leaves are small, opposite, leathery, and ovate. Boxwoods are popular for formal gardens, hedges, topiary, and containers. They are known for their dense, fine-textured foliage and ability to be shaped. While primarily outdoor plants, they are sometimes brought indoors for short periods, especially during the holidays, but long-term indoor cultivation is challenging.
Peacock Fern
Selaginella willdenowii
Selaginella willdenowii, commonly known as Peacock Fern, is a fern ally prized for its iridescent blue-green foliage. This plant is not a true fern but a spikemoss. The shimmering effect is caused by structural coloration, where light reflects off the leaf surface. It thrives in humid, shaded environments, mimicking its native rainforest habitat. While it can be grown indoors, maintaining the necessary humidity is crucial for its survival. People grow it for its unique and captivating foliage, adding a touch of exotic beauty to indoor spaces or terrariums. It is primarily an outdoor plant in tropical climates.

❓ Frequently Asked Questions — Comparing These Plants
Boxwood
What are the light requirements for Boxwood?
Boxwood prefers bright, indirect light when grown indoors. Direct sunlight can scorch the leaves, causing them to turn brown. An east-facing window is often ideal, providing gentle morning light. A north-facing window may also work, but the plant might need supplemental light, especially during winter. If using a south- or west-facing window, place the plant several feet away from the window or use sheer curtains to filter the light. Signs of insufficient light include leggy growth and pale leaves. Rotate the plant regularly to ensure all sides receive adequate light. Consider using a grow light if natural light is limited.
How do I care for Boxwood?
Boxwood thrives indoors with proper care. Provide bright, indirect light; avoid direct sunlight which can scorch the leaves. Water thoroughly when the top inch of soil is dry, ensuring good drainage to prevent root rot. Maintain moderate humidity, ideally between 40-60%. Fertilize sparingly with a balanced, slow-release fertilizer during the growing season (spring and summer). Prune regularly to maintain the desired shape and remove any dead or yellowing foliage. Repot every 2-3 years into a slightly larger pot with well-draining potting mix. Maintain stable temperatures between 60-75°F (15-24°C). Rotate the plant regularly to ensure even growth on all sides. Monitor for pests such as spider mites and treat promptly if detected. Avoid drafts and sudden temperature changes. Use a pot with drainage holes.
How do I propagate Boxwood?
Boxwood can be propagated through stem cuttings or air layering. 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 cutting in a pot filled with well-draining potting mix. Keep the soil moist and cover the pot with a plastic bag to maintain humidity. Roots should develop in 6-8 weeks. For air layering, make a shallow cut on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Once roots have formed, cut the stem below the roots and plant it in a pot.
Peacock Fern
What are the light requirements for Peacock Fern?
Peacock Fern requires bright, indirect light to maintain its vibrant color. Direct sunlight can burn its delicate fronds, causing them to turn brown and crispy. An east-facing window is ideal, providing gentle morning light. If placing it near a south- or west-facing window, use a sheer curtain to filter the light.
How do I care for Peacock Fern?
Peacock Fern thrives in bright, indirect light. Direct sunlight can scorch its delicate fronds. Maintain consistently moist soil, but avoid waterlogging. Water when the top inch of soil feels slightly dry. High humidity is crucial; aim for 60-80%. Use a humidifier, pebble tray, or group plants together to increase humidity.
How do I propagate Peacock Fern?
Peacock Fern can be propagated through division or by spores. Division is the easier method. In spring, gently remove the plant from its pot and carefully separate the root ball into smaller sections, ensuring each section has healthy fronds and roots. Plant each section in its own pot with well-draining soil. Keep the soil consistently moist and provide high humidity.
