Exacum vs Peacock Plant Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Exacum
Exacum affine
Exacum affine, commonly known as Persian Violet, is a small, bushy, herbaceous perennial often grown as an annual. It typically reaches a height of 15-30 cm. It features small, oval, glossy green leaves and a profusion of fragrant, star-shaped flowers, usually violet-blue, but also available in white, pink, and lavender. While technically a perennial, it is most often cultivated as an annual or a houseplant due to its sensitivity to cold temperatures. People grow it for its charming, long-lasting blooms and sweet fragrance.
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
Exacum
What are the light requirements for Exacum?
Exacum thrives in bright, indirect light. An east-facing window is ideal, providing gentle morning sun. Avoid direct sunlight, especially during the hottest part of the day, as it can burn the delicate leaves and fade the flowers. If you don’t have access to a bright window, consider using a grow light to supplement the natural light. Rotate the plant regularly to ensure even growth and blooming on all sides. Insufficient light can result in leggy growth and reduced flowering. If the leaves start to turn pale or yellow, it may be a sign of too much direct light.
How do I care for Exacum?
Exacum prefers bright, indirect light; direct sunlight can scorch the leaves. Water when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain moderate humidity, ideally between 50-60%. Fertilize every 2-4 weeks during the blooming season with a balanced liquid fertilizer diluted to half strength. Keep temperatures between 60-75°F (15-24°C). Prune spent flowers to encourage continuous blooming. Repot only when necessary, using a well-draining potting mix. Avoid overwatering and provide good air circulation. Monitor for pests such as aphids or spider mites and treat promptly. Deadhead regularly. Provide a consistent environment to avoid stress. Ensure adequate drainage to prevent soggy soil.
How do I propagate Exacum?
Exacum can be propagated from stem cuttings. Take a 2-3 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist and provide bright, indirect light. Cover with a plastic bag to increase humidity. Roots should develop within a few weeks. Once rooted, transplant into a larger pot. Exacum is not typically propagated by division or keiki. Ensure the cutting is free from disease or pests. Mist regularly to maintain humidity during rooting. Provide bottom heat to encourage faster root development.
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.
