Honesty vs Quaking Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Honesty
Lunaria annua
Lunaria annua, commonly known as Honesty, is a biennial plant often grown as an annual. It features heart-shaped, toothed leaves and produces clusters of fragrant, purple or white flowers in spring and summer. The plant is most prized for its distinctive, translucent, papery seedpods that resemble silver coins, hence the common names. It typically grows to a height of 60-90 cm (2-3 feet). While primarily an outdoor plant, it's grown for its ornamental seedpods, which are often dried and used in floral arrangements. It is not naturally an indoor plant and will struggle in typical indoor conditions.
Quaking Grass
Briza media
Briza media, commonly known as Quaking Grass, is a perennial grass characterized by its delicate, heart-shaped spikelets that dangle and tremble in the slightest breeze, giving it its name. It typically grows to a height of 30-70 cm. The plant features slender stems and bluish-green leaves. While primarily an outdoor plant, it is grown for its ornamental value, particularly in meadows, wildflower gardens, and dried flower arrangements. It thrives in sunny locations with well-drained soil. Indoor cultivation is challenging due to its need for full sun and specific temperature fluctuations.

💡 Pro Tips For Comparing These Plants
Honesty Care Tips
Honesty is primarily an outdoor plant and is challenging to grow indoors due to its high light requirements. It needs full sun to thrive and produce abundant seedpods. Indoor cultivation is not recommended unless you can provide very bright light and proper ventilation.
- Allow seedpods to dry on the plant before harvesting for best results.
- Provide well-draining soil to prevent root rot.
- Water regularly during dry periods, especially when plants are young.
- Deadhead spent flowers to encourage more seedpod production.
- Protect from strong winds, which can damage the seedpods.
Quaking Grass Care Tips
Quaking Grass is primarily an outdoor plant that requires full sun and well-drained soil. Indoor cultivation is difficult due to the high light requirements and the plant's natural growth habit. It can be challenging to maintain its health and vigor indoors.
- Ensure well-drained soil to prevent root rot.
- Provide full sun for optimal growth and flowering.
- Divide clumps every few years to prevent overcrowding.
- Cut back dead foliage in early spring.

❓ Frequently Asked Questions — Comparing These Plants
Honesty
What are the light requirements for Honesty?
Honesty prefers partial shade, especially in hotter climates. While it can tolerate full sun, too much direct sunlight can scorch the leaves and fade the flowers. In cooler regions, Honesty can thrive in full sun, but afternoon shade is still beneficial. When grown indoors, place Honesty near a bright, east-facing window that receives morning sun. Avoid south-facing windows that provide intense afternoon sun. If you don’t have access to natural light, you can supplement with artificial grow lights. Ensure the lights are positioned about 12-18 inches above the plant and provide at least 14-16 hours of light per day. Insufficient light can lead to leggy growth and reduced flowering.
How do I care for Honesty?
Honesty is relatively easy to care for, making it a great choice for beginner gardeners. It thrives in well-draining soil and prefers partial shade, although it can tolerate full sun in cooler climates. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize sparingly, using a balanced fertilizer in spring to promote healthy growth and flowering. Deadhead spent flowers to encourage further blooming. Honesty is typically grown as a biennial, meaning it completes its life cycle in two years. In the first year, it focuses on vegetative growth, and in the second year, it flowers and produces seedpods. After the seedpods mature and dry, they can be harvested for decorative purposes. Honesty self-seeds readily, so be prepared for new plants to appear in subsequent years. Pruning is not typically required, but you can trim back the plant after flowering to maintain its shape.
How do I propagate Honesty?
Honesty can be propagated by seeds or by division. To propagate by seeds, collect the seeds from mature seedpods and sow them in spring or fall. Sow seeds directly into the garden or start them indoors in seed trays. Keep the soil moist and provide bright, indirect light. To propagate by division, carefully dig up the plant in spring or fall and divide the root ball into several sections. Replant the divisions in fresh, well-draining soil. Ensure each division has healthy roots and shoots. Division is not always successful, as Honesty can be sensitive to root disturbance. Stem cuttings and keiki propagation are not applicable to Honesty.
Quaking Grass
What are the light requirements for Quaking Grass?
Quaking Grass thrives in full sun to partial shade. Ideally, it should receive at least six hours of direct sunlight per day for optimal growth and flowering. In hotter climates, providing some afternoon shade can help prevent scorching of the foliage. When planting in containers, choose a location that receives ample sunlight, such as a sunny patio or balcony.
How do I care for Quaking Grass?
Quaking Grass is relatively easy to care for, making it a great choice for both beginner and experienced gardeners. Plant in well-drained soil, ideally in a location that receives full sun to partial shade. Water regularly during the growing season, especially during dry spells, but avoid overwatering, as this can lead to root rot. Fertilize lightly in the spring with a balanced fertilizer to promote healthy growth and flowering.
How do I propagate Quaking Grass?
Quaking Grass can be easily propagated by division. In early spring or fall, carefully dig up the plant and divide the root clump into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-drained soil and water thoroughly.
