The Selloum plant, known for its impressive size and distinctive tropical foliage, is a popular choice for enhancing indoor spaces. Its adaptable nature makes it appealing to many plant enthusiasts.
Understanding the Selloum Plant
The Selloum plant, botanically Thaumatophyllum bipinnatifidum, was formerly Philodendron bipinnatifidum or Philodendron selloum. Other common names include Lacy Tree Philodendron, Split-Leaf Philodendron, and Tree Philodendron. This tropical perennial is native to South America’s warm, humid regions.
Defining characteristics include large, deeply lobed, glossy green leaves that grow significantly in mature plants. Over time, they develop a woody, trunk-like stem, distinguishing them from many philodendrons. While outdoor plants can reach 15 feet, indoor growth is more manageable, though still substantial.
Selloum Plant Care
Light
Selloum plants thrive in bright, indirect indoor light, ideally near a diffused light source like a north or east-facing window. Direct sunlight can scorch leaves or lighten their color, while insufficient light leads to darker green, stunted, or leggy growth. Rotate the plant periodically for even light exposure and balanced growth. Observe leaf color and growth for light requirement clues.
Watering
Selloum plants prefer consistently moist, but not soggy, soil. Allow the top 2-3 inches (5-7.5 cm) of soil to dry between waterings. Overwatering causes root rot, while underwatering leads to wilting and yellowing leaves. Water thoroughly until it drains from the pot’s bottom. Reduce watering in cooler winter months when growth slows. Use lukewarm, filtered water to prevent shock and chemical issues.
Soil
Selloum plants thrive in a well-draining potting mix rich in organic matter. A suitable mix includes perlite, orchid bark, or coarse sand for drainage and aeration, preventing waterlogging. The ideal soil pH is slightly acidic to neutral. Repot every 18-24 months, or when the plant outgrows its container, to refresh soil and provide root space.
Temperature and Humidity
Native to tropical environments, Selloum thrives in warm, humid conditions. Ideal indoor temperatures are 65-85°F (18-29°C); temperatures below 55°F (13°C) can cause stress. Protect the plant from cold drafts and direct exposure to heating or cooling vents. High humidity prevents brown leaf tips and edges. Increase humidity by misting, using a pebble tray, or a room humidifier. These practices mimic its natural habitat and support healthy foliage.
Fertilizing
During the active growing season (spring and summer), fertilize monthly with a balanced liquid fertilizer diluted to half strength. This supports vigorous growth and healthy leaf development. Stunted growth or yellowing leaves may indicate nutrient deficiency, while over-fertilization can cause brown leaf tips or edges. Avoid fertilizing in fall and winter when growth slows, as excess nutrients can harm roots.
Common Problems and Solutions
Selloum plants may show issues from improper care or environmental stress. Yellowing leaves often indicate overwatering (lack of oxygen) or underwatering (insufficient moisture); check soil moisture deeply. Brown leaf tips or edges usually point to low humidity or fertilizer salt buildup; increase humidity or flush the soil. Stunted growth suggests inadequate light or nutrients; adjust placement to brighter, indirect light and ensure consistent fertilization. Pests like spider mites, mealybugs, and aphids can infest plants, especially in dry conditions. Inspect leaves regularly and treat promptly with insecticidal soap or neem oil.
Propagating Selloum
Propagate Selloum plants using stem cuttings, ideally in spring or early summer during active growth. Select a healthy stem with 2-3 leaves and a few nodes. Make a clean cut just below a node with sterilized shears. Remove lower leaves that would be submerged to prevent rot. Place the cutting in water or a moist, well-draining potting mix. In water, roots form in weeks; transplant to soil once several inches long. For soil propagation, maintain consistent moisture and high humidity, possibly with a clear plastic cover, to encourage rooting.
Selloum Plant Toxicity
Like other Araceae family plants, Selloum contains insoluble calcium oxalate crystals. These crystals are toxic if ingested by humans or pets (dogs, cats, horses). Ingestion can cause oral irritation, pain, swelling of the mouth, tongue, and lips, excessive drooling, and vomiting. Place Selloum plants out of reach of children and pets to prevent accidental exposure.
