Ornamental Grass vs Parasol Tree Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
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.
Parasol Tree
Heptapleurum actinophyllum (syn. Schefflera actinophylla)
The Parasol Tree, or Umbrella Tree, is a fast-growing evergreen tree or shrub known for its distinctive palmate leaves that resemble an umbrella. In its native habitat, it can reach heights of up to 50 feet. It features multiple leaflets radiating from a central point, creating a visually striking effect. While primarily an outdoor plant, it is sometimes grown indoors as a houseplant, though it requires significant space and bright light to thrive. People grow it for its lush, tropical appearance and architectural form.

❓ Frequently Asked Questions — Comparing These Plants
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.
Parasol Tree
What are the light requirements for Parasol Tree?
Parasol Trees thrive in bright, indirect light. While they can tolerate lower light conditions, they will grow best and maintain their vibrant color with ample light exposure. Avoid placing the plant in direct sunlight, especially during the hottest part of the day, as this can scorch the leaves. An east-facing window is often ideal, providing gentle morning sun. A north-facing window may also work, but the plant might not grow as quickly. If you don’t have a suitable window, you can supplement with artificial grow lights. Rotate the plant regularly to ensure even light exposure on all sides. Insufficient light can lead to leggy growth and faded leaf color.
How do I care for Parasol Tree?
Provide your Parasol Tree with bright, indirect light; direct sunlight can scorch its leaves. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain a stable temperature between 65-75°F (18-24°C) and avoid sudden temperature fluctuations. 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. Prune regularly to maintain shape and encourage bushier growth. Wipe leaves with a damp cloth to remove dust and pests. Monitor for common pests like spider mites and mealybugs, treating promptly if detected. Provide adequate humidity, especially during dry winter months, by misting regularly or using a humidifier. Rotate the plant periodically to ensure even growth on all sides. Avoid overwatering, which is a common cause of problems.
How do I propagate Parasol Tree?
Parasol Trees can be propagated through stem cuttings 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 it in a well-draining potting mix. Keep the soil moist and provide warmth and humidity. Roots should develop in a few weeks. For air layering, make a small cut on a stem, wrap it with moist sphagnum moss, and cover it with plastic wrap. Secure the plastic wrap with tape. Once roots develop, cut the stem below the roots and pot the new plant. Spring and summer are the best times for propagation. Ensure the cutting or air layer receives bright, indirect light. Maintain stable conditions during the rooting process.
