Borage vs Peacock Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Borage
Borago officinalis
Borage is an annual herb characterized by its bristly, hairy stems and leaves. It typically grows to a height of 1-3 feet. The plant is primarily grown outdoors for its edible leaves and flowers, which have a cucumber-like flavor. The star-shaped, bright blue flowers are a major draw, attracting pollinators like bees. While it can be grown indoors, it requires very bright light and ample space, making it challenging for most indoor environments. It's valued for its culinary and medicinal uses.
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
Borage
What are the light requirements for Borage?
Borage thrives in full sun, requiring at least six hours of direct sunlight per day to promote abundant flowering and healthy growth. While it can tolerate partial shade, insufficient light can lead to leggy growth, reduced flowering, and paler foliage. When growing Borage indoors, place it near a south-facing window where it can receive maximum sunlight. If natural light is limited, supplement with grow lights to ensure adequate illumination. Rotate the plant regularly to ensure even light exposure on all sides. Insufficient light can weaken the plant and make it more susceptible to pests and diseases.
How do I care for Borage?
Borage is generally easy to care for, thriving in well-draining soil and full sun to partial shade. Water regularly, especially during dry periods, but avoid overwatering to prevent root rot. Fertilize lightly with a balanced fertilizer in spring to encourage blooming, switching to a bloom-boosting fertilizer as flowers appear. Deadhead spent flowers to promote continuous blooming. Borage is relatively pest-resistant but watch for aphids and spider mites. Provide adequate air circulation to prevent fungal diseases. Borage can tolerate a range of temperatures but prefers moderate conditions. Indoors, ensure adequate light and humidity. Regularly inspect your Borage for any signs of stress or disease, and adjust your care routine accordingly.
How do I propagate Borage?
Borage can be propagated easily from seeds. Sow seeds directly into the garden in spring or fall, or start them indoors 6-8 weeks before the last frost. Borage can also self-seed readily. Root cuttings can also be taken in the spring. Select a healthy stem and cut it just below a node. Remove the lower leaves and place the cutting in water or directly into moist soil. Keep the soil moist and provide bright, indirect light until roots develop. Once rooted, transplant the cutting into a pot or garden bed. Division is not suitable for Borage due to its taproot system. Borage propagation is simple and rewarding!
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.
