Bachelor's Button vs Peace Lily Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Bachelor's Button
Centaurea cyanus
Bachelor's Button, or Cornflower, is an annual plant typically grown outdoors for its vibrant blue, pink, white, or purple flowers. It features slender, grey-green leaves and an upright growth habit, reaching heights of 1 to 3 feet. While admired for its ornamental value and use in cut flower arrangements, it is primarily an outdoor plant that thrives in full sun. People grow it for its attractive flowers that attract pollinators and its ease of cultivation in gardens and fields.
Peace Lily
Spathiphyllum wallisii
The Peace Lily is a popular evergreen herbaceous perennial known for its elegant white 'flowers' (actually modified leaves called spathes) and glossy, dark green leaves. It's primarily grown as an indoor plant for its air-purifying qualities and attractive appearance. It features a clumping growth habit, arising from rhizomes. While it can be grown outdoors in very warm, humid climates, it's most commonly found as a houseplant due to its adaptability to indoor conditions and tolerance of lower light levels. The plant's beauty and ease of care make it a favorite for homes and offices.

❓ Frequently Asked Questions — Comparing These Plants
Bachelor's Button
What are the light requirements for Bachelor's Button?
Bachelor’s Buttons require at least 6-8 hours of direct sunlight each day to thrive. Insufficient light can result in leggy growth, fewer blooms, and pale foliage. Choose a location in your garden that receives full sun throughout the day. If growing indoors, place them near a south-facing window where they can receive ample sunlight.
How do I care for Bachelor's Button?
Bachelor’s Buttons thrive in full sun and well-drained soil. Water regularly, especially during dry periods, but avoid overwatering to prevent root rot. Fertilize with a balanced, slow-release fertilizer in spring to encourage abundant blooms. Deadhead spent flowers regularly to promote continuous flowering throughout the season. These plants are relatively cold-hardy but may benefit from a layer of mulch in colder climates.
How do I propagate Bachelor's Button?
Bachelor’s Buttons are primarily propagated by seed. Allow some flowers to go to seed and collect the seeds once they are dry. Sow the seeds in spring or fall in well-drained soil. Keep the soil consistently moist until germination. Thin seedlings to ensure proper spacing.
Peace Lily
What are the light requirements for Peace Lily?
Peace Lilies thrive in medium to low indirect light. Avoid direct sunlight, which can scorch their leaves. An east-facing window is ideal, providing gentle morning light. If placed near a south or west-facing window, use a sheer curtain to filter the light. Too little light can result in fewer flowers and slower growth. Observe your plant for signs of inadequate light, such as leggy growth or a lack of blooms. You can also use artificial light, such as fluorescent or LED grow lights, if natural light is limited. Rotate your plant occasionally to ensure even light exposure on all sides. Remember that darker-leaved varieties can tolerate slightly lower light levels than lighter-leaved ones.
How do I care for Peace Lily?
Peace Lilies thrive in indirect light; avoid direct sunlight to prevent leaf burn. Water thoroughly when the top inch of soil is dry, allowing excess water to drain. They prefer high humidity, so mist regularly or place near a humidifier. Fertilize sparingly during the growing season (spring/summer) with a balanced liquid fertilizer diluted to half strength. Repot every 1-2 years as needed, using a well-draining potting mix. Keep temperatures between 65-80°F (18-27°C). Prune away any yellow or brown leaves to maintain appearance. Protect from drafts and sudden temperature changes. Monitor for pests like spider mites or mealybugs and treat accordingly. Provide adequate air circulation to prevent fungal diseases. With proper care, your Peace Lily will reward you with beautiful foliage and elegant blooms.
How do I propagate Peace Lily?
Peace Lilies are commonly propagated by division. Carefully remove the plant from its pot and gently separate the root ball into smaller clumps, ensuring each clump has healthy roots and leaves. Plant each division into its own pot with fresh potting mix. Keep the soil consistently moist and provide bright, indirect light. Propagation by stem cuttings is less common but can be attempted by taking a cutting with a leaf and a node and placing it in water until roots develop before planting in soil. Air layering is another option, but it’s more complex and not typically used for Peace Lilies. Division is the most reliable method.
