Lamiaceae
Salvia rosmarinus
Sellum is a foliage houseplant known for its deeply lobed, lace-like leaves. It adds a tropical feel to any indoor space and is highly effective at purifying the air.
1. Basic Identification
Common Name: Sellum, Lace Tree Philodendron
Botanical Name: Thaumatophyllum bipinnatifidum
Arabic Name: سيلوم
2. Taxonomy & Classification
Sellum belongs to the Araceae family and the genus Thaumatophyllum. Formerly classified under the genus Philodendron (as Philodendron bipinnatifidum), it has been recently reclassified due to its unique growth habit and DNA. It is a perennial evergreen shrub known for its arborescent (tree-like) characteristics.
3. Origin & Distribution
Native to the tropical regions of South America, specifically in Brazil, Bolivia, Argentina, and Paraguay. In its natural habitat, it grows in the humid understory of forests, though it is now widely cultivated globally as an ornamental plant.
4. Visual Characteristics
The plant is famous for its large, glossy, dark green leaves that are deeply pinnatifid, meaning they are divided into many narrow lobes. As it matures, it develops a thick, woody trunk marked by distinctive circular scars left by old leaves, giving it an exotic, prehistoric appearance.
5. Size & Dimensions
When grown indoors, the Sellum typically reaches a height of 5 to 8 feet and can spread nearly as wide. In optimal outdoor conditions, it can grow significantly larger, sometimes reaching up to 15 feet in height.
6. Light Requirements
It thrives in bright, indirect sunlight. It can tolerate medium light conditions, but its growth will be slower and the leaves may be less lobed. Direct afternoon sun should be avoided as it can scorch the delicate foliage.
7. Watering Needs
Water the plant thoroughly when the top inch of soil has dried out. It prefers consistently moist but well-aerated soil. Be cautious of overwatering, as it is susceptible to root rot if left in standing water.
8. Soil & Potting
Requires a well-draining, nutrient-rich potting medium. A mixture of peat moss, perlite, and pine bark works well to provide the necessary drainage while retaining enough moisture for the roots.
9. Temperature & Humidity
Prefers temperatures between 65°F and 80°F (18°C - 27°C). It is a humidity-loving plant; if indoor air is dry, it benefits from regular misting, a pebble tray, or being placed near a humidifier.
10. Fertilization
Apply a balanced, water-soluble liquid fertilizer once a month during the spring and summer. Reduce or stop fertilization during the autumn and winter months when the plant’s growth naturally slows down.
11. Maintenance & Care Level
Maintenance is low to moderate. To keep the plant healthy, wipe the large leaves with a damp cloth periodically to remove dust. Prune away any yellow or damaged lower leaves at the base of the stem to encourage new growth.
12. Growth & Propagation
It has a moderate to fast growth rate under ideal conditions. Propagation is most successful via stem cuttings that include a node or through the planting of seeds, though the latter is a much slower process.
13. Common Problems
Susceptible to common houseplant pests like spider mites, aphids, and mealybugs. Overwatering is the most frequent issue, leading to yellowing leaves and root decay. Brown leaf tips may indicate low humidity or salt buildup from tap water.
14. Benefits & Uses
Highly valued as an "air-purifying" plant, it is effective at removing common indoor toxins such as formaldehyde. Its dramatic size and unique leaf shape make it a popular choice for interior design in homes and offices.
15. Toxicity & Safety
The plant is toxic to humans, cats, and dogs if ingested. It contains insoluble calcium oxalate crystals, which cause intense oral irritation, swelling of the throat, and digestive distress. It should be kept out of reach of children and pets.
