Everlasting Flower vs Onion Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Everlasting Flower
Xerochrysum bracteatum (formerly Bracteantha bracteata)
Xerochrysum bracteatum, commonly known as the Strawflower or Everlasting Daisy, is an annual or short-lived perennial native to Australia. It is characterized by its papery, daisy-like flowerheads that come in a wide range of colors, including white, yellow, orange, pink, red, and bronze. The plant typically grows to a height of 20-80 cm. It is widely cultivated for its long-lasting flowers, which retain their color and shape when dried, making them popular for dried flower arrangements. While it can be grown indoors, it thrives outdoors in full sun and well-drained soil.
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.

💡 Pro Tips For Comparing These Plants
Everlasting Flower Care Tips
Strawflowers are primarily outdoor plants that require full sun and well-drained soil. Growing them indoors can be challenging due to the need for intense light. Supplemental lighting is often necessary to achieve flowering. They are relatively easy to care for outdoors if their basic needs are met.
- Provide at least 6 hours of direct sunlight daily.
- Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
- Deadhead spent flowers regularly to encourage more blooms.
- Fertilize every 2-4 weeks during the growing season with a balanced liquid fertilizer.
- Ensure well-draining soil to prevent root rot.
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.

❓ Frequently Asked Questions — Comparing These Plants
Everlasting Flower
What are the light requirements for Everlasting Flower?
Everlasting Flowers require at least six hours of direct sunlight daily to thrive and produce abundant blooms. A south-facing window or a sunny spot in the garden is ideal. Insufficient light can result in leggy growth and reduced flowering. If growing indoors, rotate the plant regularly to ensure even light exposure on all sides. During periods of low light, consider supplementing with a grow light to provide the necessary intensity. When transplanting seedlings, gradually acclimate them to full sun to prevent leaf burn. Avoid placing them in overly shaded areas, as this will significantly impact their growth and flowering potential.
How do I care for Everlasting Flower?
Everlasting Flowers thrive in full sun and well-draining soil. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, which can lead to root rot. Fertilize monthly during the growing season (spring and summer) with a balanced fertilizer to encourage blooming. Deadhead spent flowers to promote continuous blooming. Provide good air circulation to prevent fungal diseases. These plants are relatively drought-tolerant once established. In colder climates, treat them as annuals or bring them indoors before the first frost. Prune back in late winter or early spring to encourage bushier growth. Protect from strong winds, which can damage the delicate bracts. Monitor for pests, such as aphids, and treat promptly.
How do I propagate Everlasting Flower?
Everlasting Flowers can be propagated by seed or stem cuttings. For stem cuttings, take 4-6 inch cuttings from healthy stems, removing the lower leaves. Dip the cut end in rooting hormone and plant in well-draining potting mix. Keep the soil moist and provide bright, indirect light. Roots should develop within a few weeks. To propagate by seed, sow seeds indoors 6-8 weeks before the last frost. Keep the soil moist and provide bright, indirect light. Seeds should germinate within 1-2 weeks. Division is not typically used for this type of plant. Keiki propagation is not applicable.
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.
