Philodendron Selloum vs Polygonatum Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Philodendron Selloum
Thaumatophyllum bipinnatifidum (syn. Philodendron selloum)
Thaumatophyllum bipinnatifidum, commonly known as Selloum, is a large, evergreen plant characterized by its deeply lobed, glossy green leaves. It is often grown as an ornamental plant, both indoors and outdoors, although it thrives best in warm, humid environments. While often referred to as a Philodendron, it was reclassified into the genus Thaumatophyllum. In its natural habitat, it can grow quite large, forming a trunk-like stem. People grow it for its dramatic foliage and tropical appearance, adding a lush, architectural element to landscapes and interiors. It is primarily an outdoor plant but can adapt to indoor conditions with proper care.
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.

❓ Frequently Asked Questions — Comparing These Plants
Philodendron Selloum
What are the light requirements for Philodendron Selloum?
Philodendron Selloum flourishes in bright, indirect light. Avoid direct sunlight, especially during the hottest part of the day, as it can cause leaf burn. An east-facing window is ideal, or a spot near a south or west-facing window that is filtered by a sheer curtain. If the plant is not receiving enough light, the leaves may become pale or the stems may become leggy. Rotate the plant regularly to ensure even growth on all sides. Artificial grow lights can be used to supplement natural light, especially during winter months.
How do I care for Philodendron Selloum?
Philodendron Selloum thrives in bright, indirect light, avoiding direct sunlight which can scorch its leaves. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain. Use a well-draining potting mix to prevent root rot. Maintain humidity levels around 60-70% through misting or a humidifier. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer. Prune any yellow or damaged leaves to encourage healthy growth. Repot every 1-2 years as needed, when the plant becomes root-bound. Provide support for mature plants as they grow larger. Protect from drafts and sudden temperature changes.
How do I propagate Philodendron Selloum?
Philodendron Selloum can be propagated through stem cuttings, division, or air layering. For stem cuttings, take a cutting with at least one node and place it in water or moist soil. For division, carefully separate the plant into multiple sections, ensuring each section has roots. For air layering, make a small cut on the stem, wrap it in moist sphagnum moss, and cover it with plastic wrap until roots develop. Plant the rooted cutting or division in well-draining soil. Maintain high humidity during propagation.
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.
