Onion vs Peacock Plant Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Onion
Allium cepa
The onion (Allium cepa) is a biennial plant, typically grown as an annual, cultivated for its edible bulb. It features hollow, bluish-green leaves and a bulb that develops at the base of the plant. Onions are primarily grown outdoors in gardens or fields. While it's possible to sprout an onion indoors, it's not typically grown to full maturity as a houseplant due to its strong odor and specific environmental needs. People grow onions for culinary purposes, adding flavor to a wide variety of dishes.
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.

💡 Pro Tips For Comparing These Plants
Onion Care Tips
Onions are primarily outdoor plants requiring full sun and well-drained soil. Growing them indoors is challenging due to their need for intense sunlight and the potential for strong odors. While sprouting an onion indoors is possible, achieving a mature bulb is difficult.
- Plant in well-drained soil amended with compost.
- Water deeply but infrequently, allowing the soil to dry slightly between waterings.
- Fertilize regularly during the growing season with a balanced fertilizer.
- Protect from pests and diseases with appropriate measures.
- Harvest when the tops begin to fall over and the bulbs are mature.
Peacock Plant Care Tips
Calathea makoyana requires consistent moisture, high humidity, and bright, indirect light. It is sensitive to tap water and temperature fluctuations. Maintaining proper humidity is crucial for preventing brown leaf edges. It can be challenging for beginners due to its specific needs.
- Use distilled or filtered water to avoid mineral buildup on leaves.
- Maintain high humidity by using a humidifier or pebble tray.
- Wipe leaves regularly to remove dust and improve photosynthesis.
- Avoid placing near drafts or heating vents.
- Rotate the plant regularly to ensure even growth.

❓ Frequently Asked Questions — Comparing These Plants
Onion
What are the light requirements for Onion?
Flowering onions require ample sunlight to thrive and produce abundant blooms. Aim for at least 6-8 hours of direct sunlight per day. Inadequate light can lead to leggy growth, weak stems, and reduced flowering. If growing indoors, place your onion plant near a south-facing window where it can receive maximum sunlight exposure. If natural light is insufficient, supplement with grow lights. Rotate the plant regularly to ensure even light distribution and prevent it from leaning towards the light source. Monitor the foliage for signs of sunburn, which can occur if the plant is exposed to intense afternoon sun. Adjust the placement or provide shade if necessary.
How do I care for Onion?
Flowering onions thrive with proper care. Plant bulbs in well-draining soil in a sunny location. Water thoroughly after planting and then moderately, allowing the soil to dry slightly between waterings. Fertilize sparingly with a balanced fertilizer during the growing season, and increase phosphorus before blooming. Deadhead spent flowers to encourage continued blooming. Provide support for taller varieties to prevent drooping. In colder climates, protect bulbs with a layer of mulch during winter. Monitor for pests and diseases, and address promptly. Ensure good air circulation to prevent fungal issues. Repot container-grown onions every few years to refresh the soil. Regular check-ups will keep your onion plant healthy and flourishing.
How do I propagate Onion?
Flowering onions can be propagated through several methods. Division is the most common and easiest. When the plant is dormant, carefully dig up the clump and separate the bulbs. Replant the individual bulbs in well-draining soil. Stem cuttings are not typically used for onion propagation. Keiki (small plantlets that form on the flower stalk) are rare in onions. For bulb offsets, detach them carefully from the mother bulb and plant them separately. Water regularly and provide adequate sunlight. Propagation is best done in the fall or early spring. Ensure the new plants have adequate space to develop their root systems. With proper care, the propagated onions will develop into mature, flowering plants within a year or two.
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.
