Leadwort vs Peacock Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Leadwort
Ceratostigma plumbaginoides
Ceratostigma plumbaginoides, commonly known as Leadwort, is a low-growing, rhizomatous perennial typically grown as a ground cover. It reaches about 10-12 inches in height and spreads via underground stems. The plant is valued for its vibrant blue flowers that appear in late summer and autumn, contrasting beautifully with its foliage, which turns bronze-red in the fall. While primarily an outdoor plant, some gardeners attempt to grow it indoors for its late-season color. However, it requires very bright light and a cool environment to thrive indoors.
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
Leadwort
What are the light requirements for Leadwort?
Leadwort requires at least six hours of direct sunlight per day for optimal blooming. In hotter climates, some afternoon shade can be beneficial to prevent scorching of the leaves. Insufficient light can result in fewer flowers and leggy growth. When grown indoors, place Leadwort near a south-facing window where it can receive ample sunlight. Rotate the plant regularly to ensure even light exposure on all sides. If natural light is insufficient, supplement with grow lights to provide the necessary intensity and duration. A lack of light can also affect the intensity of the blue flower color, resulting in paler blooms.
How do I care for Leadwort?
Leadwort thrives in well-draining soil and prefers full sun to partial shade. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize in spring with a balanced fertilizer to promote healthy growth and abundant blooms. Prune lightly in late winter or early spring to remove any dead or damaged wood and to maintain the desired shape. Deadheading spent flowers can encourage further blooming. Leadwort is generally hardy but may benefit from a layer of mulch in colder climates to protect the roots during winter. Ensure good air circulation to prevent fungal diseases. Monitor for pests such as aphids or spider mites and treat promptly if necessary. Provide support for taller varieties to prevent them from sprawling.
How do I propagate Leadwort?
Leadwort can be propagated through several methods, including division, stem cuttings, and root cuttings. For division, carefully dig up the plant in early spring or late fall and divide the root ball into smaller sections, ensuring each section has healthy roots and shoots. Replant the divisions in well-draining soil. For stem cuttings, take 4-6 inch cuttings from new growth in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist until roots develop. Root cuttings can be taken in late winter or early spring. Use healthy, pencil-thick roots, cutting them into 2-3 inch sections and planting horizontally in a rooting mix.
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.
