Grevillea vs Manila Palm Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Grevillea
Grevillea spp.
Grevilleas are a diverse genus of evergreen trees and shrubs, ranging in size from groundcovers to large trees. They are known for their distinctive, often spider-like flowers that come in a variety of colors, including red, pink, orange, yellow, and white. Most Grevilleas are outdoor plants, prized for their drought tolerance and ability to attract birds and insects. Indoor cultivation is challenging due to their high light requirements and need for excellent drainage. People grow them for their unique flowers, foliage, and wildlife attraction.
Manila Palm
Adonidia merrillii
The Manila Palm, *Adonidia merrillii*, is a single-trunked palm tree known for its compact size and ornamental appeal. It typically grows to a height of 15-25 feet outdoors. Its smooth, gray trunk is topped with a crown of arching, feathery green leaves. It is primarily an outdoor plant in tropical and subtropical climates, prized for its relatively small size and showy clusters of bright red fruits that appear around Christmas time, hence the common name 'Christmas Palm'. While sometimes grown indoors, it requires very bright light and high humidity to thrive, making it a challenging houseplant.

❓ Frequently Asked Questions — Comparing These Plants
Grevillea
What are the light requirements for Grevillea?
Grevilleas thrive in bright, direct sunlight for at least six hours each day. Insufficient light can lead to leggy growth, reduced flowering, and weakened plants. When grown indoors, place Grevilleas near a south-facing window or under grow lights to ensure adequate light exposure. Rotate the plant regularly to promote even growth on all sides. If leaves start to turn pale or yellow, it may indicate that the plant is receiving too much direct sunlight, especially during the hottest part of the day. Filtered light or partial shade during peak hours can help prevent leaf burn. Outdoor-grown Grevilleas should be planted in a location that receives full sun for most of the day.
How do I care for Grevillea?
Grevilleas require well-draining soil, ideally a sandy or gravelly loam. Water thoroughly when the top inch of soil is dry, allowing excess water to drain away. Avoid overwatering, which can lead to root rot. Provide at least 6 hours of direct sunlight daily for optimal flowering. Fertilize sparingly with a low-phosphorus fertilizer specifically formulated for native plants during the growing season (spring and summer). Prune lightly after flowering to maintain shape and encourage bushier growth. Protect from frost in colder climates. Monitor for pests such as aphids and scale, and treat as needed. Ensure good air circulation to prevent fungal diseases. Repot young plants annually in spring, using a slightly larger pot each time. Mature plants can be repotted every 2-3 years. Maintaining a slightly acidic soil pH is beneficial.
How do I propagate Grevillea?
Grevilleas can be propagated through 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 in a warm, humid environment. Rooting typically takes several weeks. Another method is seed propagation, although it can be more challenging. Collect seeds from mature seed pods and sow them in a well-draining seed starting mix. Keep the soil moist and warm until germination occurs. Division is possible for some clumping varieties. Carefully separate the plant at the roots and plant each section in its own pot.
Manila Palm
What are the light requirements for Manila Palm?
Manila Palms require bright, indirect light to thrive. Direct sunlight can scorch their leaves, so avoid placing them in areas with intense, direct sun exposure, especially during the hottest part of the day. An east-facing or west-facing window is ideal, providing ample light without the risk of sunburn. If you only have a south-facing window, filter the light with a sheer curtain. Insufficient light can lead to stunted growth and yellowing leaves. Rotate the plant regularly to ensure even light exposure on all sides. If natural light is limited, consider using a grow light to supplement.
How do I care for Manila Palm?
Manila Palms thrive in bright, indirect light, requiring at least 6 hours daily. Water thoroughly when the top inch of soil feels dry to the touch, ensuring proper drainage to prevent root rot. Maintain high humidity levels, ideally above 50%, by misting regularly or using a humidifier. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot every 2-3 years, or when the plant becomes root-bound, using a well-draining potting mix. Prune away any dead or yellowing fronds to maintain the plant’s appearance and health. Protect from drafts and sudden temperature changes. Regularly check for pests like spider mites and treat promptly if found.
How do I propagate Manila Palm?
Manila Palms are typically propagated by seeds. Soak the seeds in warm water for 24 hours before planting. Sow the seeds in a well-draining potting mix and keep them consistently moist. Germination can take several months. For clumping varieties, division is possible, carefully separate the clumps at the rootball, ensuring each division has healthy roots and foliage. Plant each division in its own pot with well-draining soil. Provide warmth and humidity to encourage root development. Keep the newly propagated plants in a bright, indirect light location and water regularly. Be patient, as establishment can be slow.
