Cornflower vs Peacock Plant 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.
Peacock Plant
Calathea makoyana
Calathea makoyana, commonly known as the Peacock Plant, is a striking tropical perennial prized for its ornamental foliage. It features large, oval leaves with intricate patterns of dark green markings against a pale green background, resembling peacock feathers. The undersides of the leaves are a rich purple. It grows in a clumping habit, reaching about 2 feet tall indoors. While it can be grown indoors, it requires specific conditions to thrive, mimicking its native humid environment. It's popular for its visually appealing leaves and ability to add a touch of the tropics to indoor spaces.

❓ 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.
Peacock Plant
What are the light requirements for Peacock Plant?
Peacock Plants thrive in bright, indirect light. Direct sunlight can damage their delicate leaves, causing them to scorch and fade. An east-facing window is often ideal, providing gentle morning light. If placed near a south- or west-facing window, use sheer curtains to filter the light. Insufficient light can lead to duller leaf patterns and slower growth. Observe your plant closely; if the leaves appear pale or bleached, it’s receiving too much light. If the leaves are losing their vibrant patterns, it may need more light. Regularly rotate the plant to ensure all sides receive adequate light exposure. Artificial grow lights can supplement natural light, especially during winter months or in darker spaces.
How do I care for Peacock Plant?
To successfully care for a Peacock Plant, provide bright, indirect light. Direct sunlight can scorch the leaves. Water thoroughly when the top inch of soil feels dry, using distilled or filtered water to avoid mineral buildup. Maintain high humidity levels, ideally above 60%, through regular misting, a humidifier, or placing the plant on a pebble tray filled with water. Keep the temperature between 65-80°F (18-27°C). Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot every 1-2 years in spring using a well-draining potting mix. Regularly check for pests and address any infestations promptly. Prune any yellow or brown leaves to maintain the plant’s appearance and health. Rotate the plant periodically to ensure even growth. Avoid placing the plant near drafts or heat sources.
How do I propagate Peacock Plant?
Peacock Plants can be propagated through division, stem cuttings, or air layering. Division is the most common method. To divide, carefully remove the plant from its pot and gently separate the root ball into sections, ensuring each section has healthy roots and foliage. Repot each section into its own pot with fresh potting mix. Stem cuttings can be rooted in water or directly in soil. Take a cutting with at least one node and place it in water until roots develop, then plant it in soil. Air layering involves encouraging roots to grow on a stem while it is still attached to the parent plant. Once roots have formed, the stem can be cut and planted. Maintain high humidity during propagation to encourage root growth.
