Ghost Plant vs Valerian Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Ghost Plant
Graptopetalum paraguayense
Graptopetalum paraguayense, commonly known as Ghost Plant, is a succulent perennial forming rosettes of fleshy, opalescent leaves. The leaves are typically pale grey or pinkish-grey, giving it a ghostly appearance. It is a relatively low-growing plant, spreading via offsets. While it can be grown indoors, it thrives in bright, sunny conditions and is more commonly used as an outdoor ground cover or in rock gardens in warmer climates. People grow it for its unique color, drought tolerance, and ease of propagation.
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.

❓ Frequently Asked Questions — Comparing These Plants
Ghost Plant
What are the light requirements for Ghost Plant?
Ghost Plant thrives in bright, indirect sunlight. It needs at least six hours of sunlight per day to maintain its vibrant colors and compact growth habit. An east- or west-facing window is ideal, providing ample light without the intensity of direct midday sun. A south-facing window can also work, but be sure to filter the light with a sheer curtain to prevent sunburn.
How do I care for Ghost Plant?
Ghost Plant is a remarkably low-maintenance succulent, ideal for beginners. Provide bright, indirect sunlight for at least six hours daily. Direct sunlight can scorch the leaves, especially during peak summer. Plant in well-draining succulent mix to prevent root rot. Water thoroughly only when the soil is completely dry, typically every 2-4 weeks, depending on the environment.
How do I propagate Ghost Plant?
Ghost Plant is incredibly easy to propagate. Leaf cuttings are a popular method: Gently twist off a healthy leaf from the stem. Allow the cut end to callous over for a few days. Place the leaf on top of well-draining succulent mix. Mist lightly every few days until roots and a new plantlet emerge.
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.
