Mirror Plant vs Ornamental Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Mirror Plant
Coprosma repens
Coprosma repens, commonly known as Mirror Bush, is a sprawling evergreen shrub or small tree native to New Zealand. It's characterized by its glossy, rounded leaves that appear almost reflective, hence the name 'Mirror Plant'. Primarily an outdoor plant, it's often used in coastal gardens for hedging, ground cover, or erosion control due to its tolerance of salt spray and wind. While it can be grown indoors, it requires very bright light and careful attention to humidity and watering to thrive. People grow it for its attractive foliage and hardiness in challenging outdoor environments.
Ornamental Grass
Pennisetum setaceum
Pennisetum setaceum, commonly known as Fountain Grass, is a perennial grass prized for its graceful, arching foliage and bottlebrush-like flower plumes. Typically grown as an annual in cooler climates, it forms dense clumps of slender, linear leaves. The flower plumes, which appear in late summer and fall, add significant ornamental value. While primarily an outdoor plant, it is sometimes grown indoors, though it requires very bright light to thrive. Fountain grass is popular for its texture, movement in the wind, and overall aesthetic appeal in gardens and landscapes.

❓ Frequently Asked Questions — Comparing These Plants
Mirror Plant
What are the light requirements for Mirror Plant?
Mirror Plant prefers bright, indirect light. Direct sunlight can scorch the leaves, causing discoloration and damage. An east-facing window is ideal, providing gentle morning sun. A north-facing window can also work, but the plant may grow more slowly. If placing near a south or west-facing window, use sheer curtains to filter the light. Rotate the plant regularly to ensure even growth on all sides. Insufficient light can result in leggy growth and dull foliage. If the leaves lose their vibrant color, it’s a sign the plant needs more light. Artificial grow lights can supplement natural light, especially during the winter months.
How do I care for Mirror Plant?
Mirror Plant thrives in bright, indirect light, but can tolerate some shade. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain away. Avoid overwatering, as this can lead to root rot. Maintain a humidity level of 50-60%, especially during dry winter months, by misting regularly or using a humidifier. Use a well-draining potting mix and fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot every 1-2 years as needed, choosing a pot only slightly larger than the previous one. Prune regularly to maintain shape and encourage bushier growth. Keep temperatures between 60-75°F (15-24°C). Protect from drafts and sudden temperature changes. Monitor for pests and treat promptly if detected. Provide adequate air circulation.
How do I propagate Mirror Plant?
Mirror Plant can be easily propagated through stem cuttings, division, or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist and provide bright, indirect light. Roots should develop within a few weeks. For division, carefully separate the root ball of a mature plant into two or more sections, ensuring each section has healthy roots and foliage. Repot each section in its own pot. Air layering involves wounding a stem, wrapping it in moist sphagnum moss, and covering it with plastic wrap until roots develop. Once roots are visible, cut the stem below the roots and pot it up.
Ornamental Grass
What are the light requirements for Ornamental Grass?
Ornamental grasses require ample sunlight to thrive and produce their characteristic flower plumes. Aim for at least six hours of direct sunlight per day. A south-facing window is ideal for indoor plants. Insufficient light can result in leggy growth, poor flowering, and faded foliage color. If your grass is not receiving enough natural light, consider supplementing with a grow light. Rotate the plant regularly to ensure even light exposure on all sides. Some varieties can tolerate partial shade, but full sun is generally preferred for optimal performance. Observe your plant closely and adjust its location as needed to provide the best possible light conditions.
How do I care for Ornamental Grass?
Ornamental grasses thrive with regular care. Provide them with at least six hours of direct sunlight daily for optimal growth and flowering. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Fertilize sparingly in the spring with a balanced fertilizer to encourage healthy growth and bloom production. Prune back dead or damaged foliage in late winter or early spring before new growth emerges. Ensure good air circulation to prevent fungal diseases. Amend heavy clay soils with organic matter to improve drainage. Mulch around the base of the plant to retain moisture and suppress weeds. Monitor for pests and diseases and treat promptly. Repot container-grown grasses every few years to refresh the soil and provide more space for roots. Maintain moderate humidity levels, especially for indoor plants.
How do I propagate Ornamental Grass?
Ornamental grasses can be propagated through division. In early spring or fall, dig up the plant and carefully separate the root ball into smaller clumps. Each clump should have healthy roots and foliage. Replant the divisions in well-draining soil. Water thoroughly and keep the soil moist until new growth emerges. Stem cuttings are less common but can be taken in spring. Take 4-6 inch cuttings from new growth, remove lower leaves, and root in water or moist potting mix. Keikis (small plantlets that grow on the flower stalks) are rare but can be carefully removed and potted up. Provide bright, indirect light and consistent moisture to encourage rooting.
