Peacock Fern vs Perennial Geranium Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
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.
Perennial Geranium
Geranium spp.
Perennial Geraniums, also known as Cranesbills, are herbaceous perennials prized for their attractive foliage and long-lasting blooms. They form mounds of often deeply lobed or dissected leaves, ranging in color from green to bronze, depending on the species and cultivar. They are primarily outdoor plants, valued for their ability to suppress weeds and provide ground cover. People grow them for their colorful flowers, which come in shades of pink, purple, blue, white, and magenta, and their generally easy-care nature in garden settings. While some may attempt to grow them indoors, they typically struggle to thrive without sufficient sunlight and air circulation.

❓ Frequently Asked Questions — Comparing These Plants
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.
Perennial Geranium
What are the light requirements for Perennial Geranium?
Perennial Geraniums thrive in partial shade, especially in warmer climates. They can tolerate full sun, but in hot regions, afternoon shade is essential to prevent scorching of the leaves. A location that receives morning sun and afternoon shade is ideal. Insufficient light can lead to leggy growth and reduced flowering.
How do I care for Perennial Geranium?
Perennial Geraniums are generally easy to care for, making them a great choice for beginners. Plant them in well-draining soil and provide regular watering, especially during dry periods. Fertilize in early spring with a balanced fertilizer to encourage healthy growth and abundant blooms. Deadhead spent flowers regularly to promote continuous flowering throughout the season.
How do I propagate Perennial Geranium?
Perennial Geraniums can be propagated through division, stem cuttings, or seeds. Division is best done in spring or fall. Carefully dig up the plant and divide the root ball into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-draining soil. For stem cuttings, take 4-6 inch cuttings from healthy stems 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 they root. Seed propagation can be done by sowing seeds indoors in early spring. Keep the soil moist and provide warmth until germination occurs. Transplant seedlings outdoors after the last frost. Using a humidity dome during rooting increases success.
