Paper Flower vs Valerian Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Paper Flower
Bougainvillea spp.
Bougainvillea is a thorny, woody vine or shrub known for its vibrant, papery bracts that surround small, inconspicuous flowers. It is primarily an outdoor plant, thriving in warm climates with plenty of sunlight. Bougainvilleas are popular for their showy displays of color, often used to adorn walls, fences, and pergolas. While some attempt to grow them indoors, it's challenging to replicate their ideal growing conditions, and they rarely thrive as houseplants. They are grown for their vibrant bracts, not the actual flowers.
Valerian
Valeriana officinalis
Valeriana officinalis is a perennial flowering plant with a distinctive odor, growing up to 1.5 meters (5 feet) tall. It features pinnate leaves and clusters of small, fragrant white or pink flowers that bloom in the summer. Primarily an outdoor plant, it thrives in moist, well-drained soil and full to partial sun. Valerian is cultivated for its rhizomes and roots, which are used in herbal medicine as a sleep aid and to reduce anxiety. Growing it indoors is challenging due to its size and light requirements.

💡 Pro Tips For Comparing These Plants
Paper Flower Care Tips
Bougainvillea is challenging to grow indoors due to its high light requirements. It needs at least 6 hours of direct sunlight daily to thrive and produce its colorful bracts. Without sufficient light, it will become leggy, produce few bracts, and be susceptible to pests and diseases. Requires careful watering and well-draining soil.
- Provide at least 6 hours of direct sunlight daily.
- Water thoroughly when the top inch of soil is dry, but avoid overwatering.
- Fertilize regularly during the growing season with a balanced liquid fertilizer.
- Prune after each flush of bracts to encourage new growth and flowering.
- Protect from frost and freezing temperatures.
Valerian Care Tips
Valerian is primarily an outdoor plant and requires full sun and well-drained soil. Indoor cultivation is difficult due to its size and high light requirements. It can be challenging to provide adequate conditions indoors, and it may not thrive.
- Provide well-drained soil to prevent root rot.
- Ensure at least 6 hours of direct sunlight daily.
- Water deeply but infrequently, allowing the soil to dry slightly between waterings.
- Fertilize sparingly in the spring.
- Monitor for pests and diseases regularly.

❓ Frequently Asked Questions — Comparing These Plants
Paper Flower
What are the light requirements for Paper Flower?
Paper Flowers are sun-loving plants and require at least 6 hours of direct sunlight each day to produce abundant blooms. Insufficient light will result in fewer flowers and leggy growth. The ideal placement for a Paper Flower is a south-facing window or a sunny patio or balcony. If growing indoors, consider supplementing with grow lights, especially during the winter months when natural light is limited.
How do I care for Paper Flower?
Paper Flowers require bright, direct sunlight for at least 6 hours a day to thrive and produce vibrant blooms. Plant them in well-draining soil, such as a mix of potting soil, perlite, and sand. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, as this can lead to root rot. During the growing season (spring and summer), fertilize regularly with a balanced fertilizer diluted to half strength, or a fertilizer specifically formulated for blooming plants, to encourage abundant flower production.
How do I propagate Paper Flower?
Paper Flowers can be propagated through stem cuttings, division, or, less commonly, keiki.
Valerian
What are the light requirements for Valerian?
Valerian flourishes in full sun to partial shade. Ideally, it should receive at least six hours of direct sunlight daily for optimal growth and abundant flowering. In hotter climates, provide afternoon shade to prevent scorching of the leaves. When grown indoors, place Valerian near a sunny window, preferably south-facing. If natural light is insufficient, supplement with grow lights to ensure adequate illumination. Insufficient light can result in leggy growth and reduced flowering. Rotate the plant regularly to ensure even exposure to light on all sides.
How do I care for Valerian?
Valerian thrives in well-drained soil and prefers full sun to partial shade. Water regularly, keeping the soil consistently moist but not waterlogged. Fertilize during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength, to encourage blooming. Deadhead spent flowers to promote continuous flowering. Valerian is relatively low-maintenance, but it can benefit from occasional pruning to maintain its shape and prevent overcrowding. It’s generally pest and disease-resistant. Provide adequate air circulation to prevent fungal issues. In colder climates, Valerian may die back in winter but will regrow in spring. Consider container growing if you want to control its spread.
How do I propagate Valerian?
Valerian can be propagated through division, stem cuttings, or seed. Division is best done in spring or fall. Carefully dig up the plant and separate the roots into smaller clumps, ensuring each clump has healthy roots and foliage. Replant the divisions in well-drained soil. For stem cuttings, take 4-6 inch cuttings from healthy stems in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist until roots develop. Growing from seed is also possible, sow seeds indoors in early spring or directly into the garden after the last frost.
