If you’re looking for a truly special houseplant, the philodendron martianum is a rare and captivating choice. Its unique look makes it a standout in any collection, and caring for it is easier than you might think.
This plant, sometimes called the “Pacova” or “Martianum Philodendron,” is native to Brazil. It’s known for its thick, almost succulent-like stems and glossy, deep green leaves. The leaves emerge from a swollen, bulbous base called a petiole, which gives it a sculptural, otherworldly appearance. It’s a slow grower, making each new leaf a special event.
Philodendron Martianum
This plant belongs to the Araceae family, and it’s an epiphyte in the wild. That means it grows on other plants or trees, not in soil. Understanding this helps us recreate its perfect home environment. It’s not the cheapest plant you’ll find, but its unique beauty makes it worth the search for many enthusiasts.
Why This Plant Is So Special
What makes the philodendron martianum so sought after? It’s all about the details.
- The Petioles: The most distinctive feature. They are thick, fleshy, and store water, resembling little green bottles or balloons.
- Leaf Structure: The leaves are lance-shaped, rigid, and have a beautiful glossy sheen. They are attached to the end of those dramatic petioles.
- Growth Habit: It has a compact, upright growth pattern. It won’t quickly take over your space like some other vining philodendrons.
- Rarity: It’s less common in big-box stores, which adds to its appeal for collectors looking for something different.
Your Complete Care Guide
Don’t let its rarity intimidate you. With a few key tips, you can keep your philodendron martianum thriving.
Light Requirements
This plant prefers bright, indirect light. Think of the dappled light it would get under a forest canopy.
- A spot near an east or north-facing window is often ideal.
- A few feet back from a south or west window with a sheer curtain works well too.
- Avoid direct, harsh sunlight, which can scorch those beautiful leaves. If the leaves start to look pale or washed out, it might be getting to much light.
Watering The Right Way
Overwatering is the biggest threat. Those chunky petioles hold water, so the plant can handle some drought.
- Check the soil first. Stick your finger about 2 inches into the potting mix.
- Water thoroughly only when the top half of the soil feels dry.
- Water until it runs out the drainage holes, then let the pot drain completely.
- In winter, reduce watering frequency as growth slows down.
Soil and Potting Mix
It needs a mix that drains exceptionally fast. A standard houseplant soil will hold to much moisture.
A simple recipe is:
- 1 part high-quality indoor potting soil
- 1 part orchid bark or coconut husk chips
- 1 part perlite or pumice
- A handful of horticultural charcoal (optional, but helps keep the mix fresh)
Always use a pot with drainage holes. A terracotta pot is a great choice because it wicks away extra moisture from the soil.
Humidity and Temperature
As a tropical plant, it appreciates higher humidity but is often adaptable to average home levels (around 40-50%).
- If your air is very dry, use a humidifier or place the pot on a pebble tray with water.
- Ideal temperatures are between 65°F and 80°F (18°C – 27°C).
- Keep it away from cold drafts, air conditioners, and heating vents, which can cause stress.
Feeding and Fertilizing
Feed your plant during its active growing season (spring and summer).
- Use a balanced, water-soluble houseplant fertilizer, diluted to half the recommended strength.
- Apply it once a month. You can reduce this to every 6-8 weeks in fall and winter, or stop altogether.
- Never fertilize a dry plant; always water it first to avoid root burn.
Common Problems and Solutions
Even with great care, you might encounter an issue. Here’s how to troubleshoot.
Yellowing Leaves
This is usually a sign of overwatering. Check your soil moisture and ensure the pot drains well. Older leaves yellowing naturally is normal occassionaly.
Brown Leaf Tips or Edges
This often points to low humidity or a buildup of salts and minerals from tap water or fertilizer. Try using distilled or rainwater, and flush the soil every few months.
Pests
Keep an eye out for common pests like spider mites, mealybugs, and scale. Wipe leaves regularly with a damp cloth and inspect the stems. If you see pests, treat early with insecticidal soap or neem oil.
Leggy Growth or Small Leaves
This typically means the plant isn’t getting enough light. Move it to a brighter location (but not into direct sun).
Propagation Tips
You can create new plants from your philodendron martianum through division or stem cuttings.
- Division: Best done when repotting. Gently separate a section of the plant that has its own roots and at least one growth point. Pot it up separately.
- Stem Cuttings: Take a cutting with at least one node (the bump on the stem where leaves and roots grow). You can root it in water or directly in a moist sphagnum moss/perlite mix. Change the water weekly if using that method.
Patience is key! Rooting can take several weeks to a couple months, especially since this is a slower-growing plant.
Repotting Your Plant
Because it’s slow-growing, you’ll only need to repot every 2-3 years.
- Signs it’s time: roots growing out of the drainage holes, or the plant drying out extremely quickly.
- Only go up one pot size (1-2 inches larger in diameter).
- The best time to repot is in the spring or early summer, when the plant is entering its active growth phase.
Frequently Asked Questions (FAQ)
Is the Philodendron martianum toxic?
Yes, like all philodendrons, it contains calcium oxalate crystals which are toxic to pets and humans if ingested. Keep it out of reach of curious cats, dogs, and children.
How fast does a Martianum Philodendron grow?
It is considered a slow to moderate grower, especially indoors. You can expect a few new leaves each growing season under optimal conditions.
Why are the stems on my philodendron martianum so swollen?
Those are the petioles, and they’re supposed to be swollen! That’s a key feature of the plant. They act as water storage organs, helping it survive dry periods.
Can I grow this as a hanging plant?
It has a more upright, clumping habit rather than a long, trailing one. It’s best displayed on a table, shelf, or plant stand where its full form can be appreciated.
Where can I buy a philodendron martianum?
Check specialized online plant shops, Etsy, or local plant nurseries that carry rare aroids. Be prepared for it to be more expensive than common houseplants due to its rarity and slow growth.
Adding a philodendron martianum to your home brings a piece of unique, living sculpture. Its care routine is straightforward once you understand its needs for light, a well-draining home, and careful watering. Pay attention to its signals, and you’ll be rewarded with a healthy, captivating plant for years to come.
