Grevillea vs Lacy Tree Philodendron 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.
Lacy Tree Philodendron
Thaumatophyllum bipinnatifidum
Thaumatophyllum bipinnatifidum, commonly known as the Lacy Tree Philodendron or Selloum, is a large, evergreen plant characterized by its deeply lobed, glossy green leaves. Despite its common name, it is not a true philodendron. It exhibits a shrub-like growth habit, developing a thick, trunk-like stem as it matures. While it can reach impressive sizes outdoors, indoor specimens remain more manageable. It's popular for its bold, tropical appearance and relatively easy care, making it a statement piece in homes and offices.

❓ 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.
Lacy Tree Philodendron
What are the light requirements for Lacy Tree Philodendron?
Lacy Tree Philodendrons require bright, indirect light to thrive. Direct sunlight can scorch their leaves, causing unsightly burns. An east-facing window is often ideal, providing gentle morning sun. A north-facing window can also work, but the plant may grow slower. If placed near a south or west-facing window, use a sheer curtain to filter the intense light. Insufficient light can lead to leggy growth and smaller, less-defined leaves. Rotate the plant regularly to ensure even light exposure on all sides. Monitor the leaves for signs of light stress, such as yellowing or browning.
How do I care for Lacy Tree Philodendron?
Lacy Tree Philodendrons thrive in bright, indirect light; avoid direct sunlight to prevent leaf burn. Water when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain humidity levels around 60-70% 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 1-2 years, or when the plant becomes root-bound, using a well-draining potting mix. Provide support, such as a moss pole, as the plant matures and its aerial roots develop. Regularly wipe the leaves to remove dust and pests. Keep temperatures between 65-80°F (18-27°C).
How do I propagate Lacy Tree Philodendron?
Lacy Tree Philodendrons can be easily propagated through stem cuttings, division, or air layering. For stem cuttings, take a cutting with at least one node and place it in water or directly into moist potting mix. Keep the cutting in a warm, humid environment until roots develop. For division, carefully separate the root ball into smaller sections and repot each section into its own container. Air layering involves wrapping a node with moist sphagnum moss and covering it with plastic wrap until roots form, then cutting below the roots and potting the new plant.
