Philodendron selloum, also known as the tree philodendron, is more than just a pretty face in the plant world. It’s a statement piece, a conversation starter, and a testament to nature’s artistry. Whether you’re a seasoned plant parent or a budding enthusiast, this article will guide you through the intricacies of nurturing and enjoying this botanical wonder.

Scientific Classification and Nomenclature

Before we delve deeper into the care and cultivation of this plant, let’s address its identity. The scientific name of what we commonly call Philodendron selloum has undergone a recent change in the botanical world.

Scientific Name: Thaumatophyllum bipinnatifidum

Yes, you read that right! Our beloved Philodendron selloum has been reclassified. While many of us still use the old name out of habit, it’s important to note that botanists now recognize it as Thaumatophyllum bipinnatifidum. This change came about due to new understandings in plant taxonomy.

Common Names

Despite its scientific reclassification, this plant goes by several common names that are still widely used:

• Tree philodendron
• Lacy tree philodendron
• Horsehead philodendron

These names often reflect the plant’s appearance or growth habits. The term “tree philodendron” nods to its impressive size when mature, while “lacy” refers to its intricately lobed leaves.

Physical Characteristics

One of the most striking features of Philodendron selloum is its impressive size and distinctive foliage. Let’s explore what makes this plant so visually appealing.

Size and Growth Habit

In its natural habitat, Philodendron selloum can grow to be quite large, reaching heights of 10-15 feet with a spread just as wide. When grown indoors, however, it tends to be more modest in size, typically reaching 4-6 feet tall. The plant has a tree-like growth habit, developing a thick, sturdy trunk over time.

Leaf Structure and Appearance

The leaves of Philodendron selloum are nothing short of spectacular. They are large, often measuring 2-3 feet long and nearly as wide. The deep green leaves are deeply lobed, giving them a dramatic, tropical appearance. The glossy surface of the leaves adds to their visual appeal, reflecting light and adding depth to their appearance.

Stem and Root System

As the plant matures, it develops a thick, woody stem that can resemble a tree trunk. This stem provides support for the massive leaves. The root system is equally impressive, with thick, fleshy roots that can become aerial roots in high humidity environments.

Varieties and Cultivars

While the classic Philodendron selloum is a stunner on its own, there are several varieties and cultivars that offer unique characteristics:

1. ‘Hope’ Philodendron: A compact variety with smaller, more deeply lobed leaves.
2. ‘Xanadu’: Another compact variety with a more bushy growth habit.
3. ‘Little Phil’: A dwarf variety perfect for smaller spaces.
4. ‘Winterbourn’: Known for its particularly large and deeply cut leaves.

These varieties offer options for different space requirements and aesthetic preferences, making Philodendron selloum adaptable to various home environments.

Natural Habitat and Distribution

Understanding a plant’s natural habitat helps us provide better care in our homes. Philodendron selloum is native to South America, particularly southern Brazil, Bolivia, Argentina, and Paraguay. In these regions, it thrives in tropical and subtropical forests.

In its natural environment, Philodendron selloum often starts life as an epiphyte, growing on other plants or trees. As it matures, it can become terrestrial, rooting in the forest floor. This adaptability is part of what makes it such a resilient houseplant.

Philodendron selloum Care Guide

Now that we’ve covered the basics, let’s dive into the heart of the matter: how to care for your Philodendron selloum. With the right attention, this plant can thrive and become a stunning centerpiece in your home.

Light Requirements

Philodendron selloum is adaptable when it comes to light, but it does have preferences:

• Optimal light: Bright, indirect light is ideal. This mimics the dappled sunlight it would receive in its natural forest habitat.
• Adapting to different light levels: While it can tolerate lower light conditions, growth may slow, and leaves might become smaller. In very low light, the plant may become leggy as it stretches towards light sources.
• Avoid direct sunlight: Too much direct sun can scorch the leaves, causing brown patches.

A north or east-facing window often provides the perfect light balance for this tropical beauty.

Watering Needs

Proper watering is crucial for the health of your Philodendron selloum:

• Watering frequency: Allow the top inch of soil to dry out between waterings. This usually means watering once a week, but frequency can vary based on environmental conditions.
• Watering technique: Water thoroughly until it runs out of the drainage holes, then empty the saucer. This ensures the roots receive ample hydration.
• Signs of overwatering: Yellowing leaves, especially lower leaves, and soft, mushy stems are indicators of overwatering.
• Signs of underwatering: Drooping leaves and dry, crispy edges suggest the plant needs more water.

Remember, it’s better to underwater slightly than to overwater. Philodendron selloum is more forgiving of dry conditions than waterlogged soil.

Soil and Potting

The right soil mix is essential for healthy growth and to prevent issues like root rot:

• Ideal soil composition: A well-draining, rich potting mix is best. A combination of peat moss, perlite, and regular potting soil works well.
• Soil pH: Philodendron selloum prefers slightly acidic to neutral soil, with a pH between 5.5 and 7.0.
• Repotting guidelines: Repot every 2-3 years or when the plant outgrows its current pot. Choose a pot that’s 2-3 inches larger in diameter than the current one.

When repotting, be gentle with the roots and use fresh potting mix to provide new nutrients.

Temperature and Humidity

As a tropical plant, Philodendron selloum has specific temperature and humidity needs:

• Optimal temperature range: 65°F to 80°F (18°C to 27°C) is ideal. The plant can tolerate brief periods outside this range but may show stress.
• Humidity requirements: High humidity is appreciated, ideally above 60%. In drier environments, consider using a humidifier or placing the plant on a pebble tray filled with water.

Avoid placing your Philodendron selloum near drafty windows or air conditioning vents, as sudden temperature changes can shock the plant.

Fertilization

Proper fertilization helps maintain the lush, healthy appearance of your Philodendron selloum:

• Types of fertilizers: A balanced, water-soluble fertilizer with an NPK ratio of 20-20-20 works well.
• Fertilization schedule: Feed monthly during the growing season (spring and summer), and reduce or stop fertilizing in fall and winter.
• Dosage: Always follow the instructions on the fertilizer package, but generally, it’s better to under-fertilize than over-fertilize.

If you notice pale leaves or slow growth, your plant might benefit from additional fertilization. However, be cautious, as over-fertilizing can lead to burnt leaf tips and other issues.

Propagation Methods

Propagating Philodendron selloum is a rewarding way to expand your plant collection or share with friends. Here are the most effective methods:

Stem Cutting Propagation

1. Choose a healthy stem with at least two leaves and a node.
2. Cut just below a node using clean, sharp scissors.
3. Remove the lower leaves, leaving 1-2 at the top.
4. Place the cutting in water or moist potting mix.
5. Keep in a warm, bright spot out of direct sunlight.
6. Roots should develop in 3-4 weeks.

Air Layering Technique

1. Choose a healthy stem with aerial roots.
2. Make a small incision in the stem below a node.
3. Wrap the area with damp sphagnum moss and secure with plastic wrap.
4. Roots will form in the moss over several weeks.
5. Once roots are visible, cut below the rooted section and pot.

Division of Mature Plants

1. Gently remove the plant from its pot.
2. Identify natural divisions in the root ball.
3. Carefully separate the divisions, ensuring each has roots and leaves.
4. Pot each division in fresh potting mix.

Growth and Size Management

Managing the size of your Philodendron selloum is important, especially in indoor settings:

• Pruning techniques: Regular pruning helps maintain shape and size. Use clean, sharp pruning shears and cut just above a leaf node.
• Controlling size: Pruning larger leaves and limiting pot size can help control growth.
• Supporting large specimens: As the plant grows, it may need support. Use a moss pole or trellis to guide growth.

Remember, pruning also encourages bushier growth, helping your Philodendron selloum maintain a fuller appearance.
