Polygonatum vs Valerian Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Polygonatum
Polygonatum multiflorum
Polygonatum multiflorum, commonly known as Solomon's Seal, is a rhizomatous perennial plant typically found in woodland settings. It features arching stems that can reach up to 3 feet in height, adorned with pairs of oval-shaped leaves along the stem. In spring, it produces small, bell-shaped, white or greenish-white flowers that hang beneath the leaves. It is primarily grown for its elegant foliage and graceful form in shade gardens. While it can be grown in containers, it is primarily an outdoor plant and may struggle indoors due to light and humidity requirements.
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
Polygonatum
What are the light requirements for Polygonatum?
Polygonatum prefers partial to full shade, mimicking its natural woodland habitat. Direct sunlight can scorch the leaves, so avoid placing it in areas with intense afternoon sun. A location with dappled sunlight or morning sun is ideal. If grown indoors, place it near a north-facing window or in a spot that receives filtered light. Insufficient light can result in leggy growth and reduced flowering. Observe the plant’s foliage; if the leaves appear pale or bleached, it may be receiving too much light. Adjust its location accordingly to provide optimal light conditions.
How do I care for Polygonatum?
Polygonatum thrives in partial to full shade and prefers well-draining, moist soil. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize in early spring with a balanced, slow-release fertilizer to encourage healthy growth and flowering. Mulch around the base of the plant to retain moisture and suppress weeds. Prune away any dead or damaged foliage to maintain the plant’s appearance. In colder climates, provide winter protection by mulching heavily around the base of the plant. Monitor for pests such as slugs and snails and take appropriate action if necessary. Provide support if the stems become too heavy with blooms.
How do I propagate Polygonatum?
Polygonatum can be propagated by division, which is best done in early spring or fall. Carefully dig up the plant and separate the rhizomes, ensuring each division has healthy roots and shoots. Replant the divisions in well-draining soil. Stem cuttings are less common but can be attempted. Take a stem cutting in spring and root it in water or moist perlite. Keiki are not produced by Polygonatum. Keep the cuttings in a humid environment until roots develop. Ensure the new plants are provided with adequate shade and moisture. Water regularly and fertilize lightly.
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.
