Cornflower vs Parasol Tree Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Cornflower
Centaurea cyanus
Cornflower (Centaurea cyanus) is an annual plant typically grown outdoors for its vibrant blue flowers, though pink, white, and purple varieties exist. It reaches a height of 1 to 3 feet. Its slender, grey-green leaves provide a backdrop for the showy, thistle-like flower heads. While it can be grown indoors, it requires very bright light and is challenging to maintain as a healthy, flowering plant indoors due to its need for full sun and cool temperatures. It is often grown in cottage gardens and wildflower meadows.
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
Cornflower
What are the light requirements for Cornflower?
Cornflowers require at least six hours of direct sunlight per day to thrive and produce abundant blooms. When grown indoors, place them near a south-facing window where they can receive ample sunlight. If natural light is insufficient, supplement with grow lights. Insufficient light can lead to leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure on all sides. Avoid placing cornflowers in areas with heavy shade, as this will hinder their growth and flowering potential. Strong, direct morning sunlight is ideal, followed by slightly filtered light in the afternoon.
How do I care for Cornflower?
Cornflowers thrive in full sun and well-drained soil. Water regularly, especially during dry periods, but avoid overwatering to prevent root rot. Fertilize monthly with a balanced fertilizer during the growing season to promote abundant blooms. Deadhead spent flowers to encourage continuous blooming. Cornflowers are relatively low-maintenance and can tolerate a range of conditions, but they prefer cooler temperatures. Protect them from strong winds, which can damage their delicate stems. In warmer climates, provide some afternoon shade to prevent scorching. Monitor for pests like aphids and treat promptly if necessary. With proper care, cornflowers will reward you with a long season of beautiful blooms.
How do I propagate Cornflower?
Cornflowers are primarily propagated by seed. Direct sow seeds in the garden in early spring or fall. Sow seeds thinly and cover lightly with soil. Keep the soil moist until germination. Alternatively, start seeds indoors and transplant seedlings outdoors after the last frost. Cornflowers can also self-sow if allowed to go to seed. While division and cuttings are possible, they are less common methods for cornflowers. Collect seeds from dried flower heads for future planting. Ensure seeds are stored in a cool, dry place.
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.
