Scindapsus treubii ‘Dark Form’ Care & Growing Guide

Overview

Scindapsus treubii ‘Dark Form’ is a striking, slow-growing tropical vine prized for its nearly black, satin-finished leaves. Native to the humid forests of Southeast Asia, particularly Indonesia and the Philippines, it is a member of the Araceae family. In its natural habitat, this plant climbs tree trunks or trails along the forest floor, benefiting from filtered light and consistent moisture. Its rarity and dramatic foliage make it a sought-after species among houseplant collectors.

This guide covers everything you need to know to successfully grow and maintain Scindapsus treubii ‘Dark Form’ indoors, from light and watering to propagation and styling tips.

Identification & Growth Habit

The ‘Dark Form’ variety is recognized by its thick, elongated, lance-shaped leaves with a deep green so dark it appears black under certain lighting. The foliage has a subtle sheen and a leathery texture. Stems are vining and can either trail from a hanging basket or climb when given support such as a moss pole or trellis. Growth is generally slow to moderate, especially in lower light conditions.

• Leaf size: Typically 4–8 inches long when mature.
• Growth type: Climbing or trailing vine.
• Mature height: Indoors, 3–6 feet with support.

Light & Placement

Scindapsus treubii ‘Dark Form’ thrives in bright, indirect light. Place it near an east- or north-facing window, or a few feet back from a south- or west-facing window with sheer curtains. It can tolerate lower light, but growth will be slower and leaves may be smaller. Avoid direct midday sun, which can scorch the foliage.

For even growth, rotate the plant every few weeks so all sides receive light.

Watering & Humidity

Water when the top 2–3 inches of soil feel dry to the touch. Use room-temperature water and ensure excess drains freely from the pot. Overwatering can lead to root rot, so never let the plant sit in standing water. During the cooler months, reduce watering frequency to match slower growth.

This species prefers high humidity—ideally above 50%. If your home is dry, especially in winter, use a humidifier, place the pot on a pebble tray with water, or group it with other plants to create a microclimate.

Soil & Repotting

Use a well-draining potting mix rich in organic matter. A recommended blend is:

• 2 parts peat-based potting soil
• 1 part perlite
• 1 part orchid bark

This combination retains moisture while allowing air to reach the roots. Repot every 2–3 years or when the plant becomes root-bound, ideally in spring. Choose a pot with drainage holes to prevent excess moisture buildup.

Fertilizing

Feed monthly during the active growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Reduce feeding in autumn and winter when growth slows. Avoid over-fertilizing, which can cause salt buildup and damage roots.

Pruning & Training

Pruning helps maintain shape and encourage fuller growth. Use clean, sharp scissors to trim leggy stems just above a node. You can train Scindapsus treubii ‘Dark Form’ to climb by tying stems loosely to a moss pole, trellis, or other support. Climbing growth often produces larger leaves compared to trailing.

Propagation

This plant propagates reliably from stem cuttings. Here’s a step-by-step guide:

1. Select a healthy stem with at least one node and one or two leaves.
2. Cut just below the node using sterilized scissors or pruners.
3. Remove the leaf closest to the cut end to expose the node.
4. Place the cutting in water or directly into moist, well-draining soil, ensuring the node is submerged or buried.
5. If rooting in water, change the water every few days. If rooting in soil, keep it evenly moist but not soggy.
6. Provide bright, indirect light and maintain warmth (above 65°F / 18°C).
7. Roots typically develop in 3–6 weeks. Once established, pot into the desired container.

Common Problems

Pests

• Spider mites: Look for fine webbing and stippled leaves. Increase humidity and treat with insecticidal soap or neem oil.
• Mealybugs: White cottony clusters on stems or leaf joints. Remove manually with a cotton swab dipped in alcohol and follow up with treatment.
• Scale insects: Brown, shell-like bumps. Scrape off gently and treat with horticultural oil.

Diseases

• Root rot: Caused by overwatering and poor drainage. Remove affected roots, repot in fresh soil, and adjust watering practices.
• Leaf spot: Brown or yellow spots from fungal or bacterial infection. Remove affected leaves and improve air circulation.

Toxicity & Pet Safety

Scindapsus treubii ‘Dark Form’ is toxic if ingested by pets or humans due to the presence of calcium oxalate crystals. Keep out of reach of cats, dogs, and children. Symptoms of ingestion in pets may include drooling, pawing at the mouth, and vomiting; contact a veterinarian if exposure occurs.

Styling & Decor Tips

The deep, almost-black foliage of this plant creates a dramatic contrast against lighter walls and décor. Use it as a statement piece on a plant stand, or allow it to trail from a hanging planter. For a lush, vertical display, train it up a moss pole where the leaves can grow larger and more pronounced.

Varieties & Cultivars

Within the Scindapsus treubii species, the ‘Dark Form’ is distinct for its solid, dark foliage. Another popular variety is Scindapsus treubii ‘Moonlight’, which has silvery-green leaves. Both share similar care requirements but offer different aesthetic appeal.

Buying Tips & Maturity

When purchasing, look for healthy, firm leaves without yellowing or spots, and inspect the stems for pests. Because it is a slow grower, larger specimens may be more expensive and harder to find. Young plants may have smaller leaves, which will increase in size with maturity and climbing support.

Seasonal Care

• Spring/Summer: Active growth phase—water regularly, fertilize monthly, and consider repotting if needed.
• Autumn/Winter: Growth slows—reduce watering and stop fertilizing. Maintain warmth and humidity, and keep away from cold drafts.

FAQ

• How fast does Scindapsus treubii ‘Dark Form’ grow?
  It is generally a slow to moderate grower, with faster growth in bright, indirect light and warm, humid conditions.
• Can it live in low light?
  Yes, it can tolerate low light, but growth will be slower and leaves may be smaller.
• Should I mist the leaves?
  Occasional misting can help raise humidity, but it’s more effective to use a humidifier or pebble tray for consistent moisture in the air.
• Does it need a moss pole?
  Not required, but providing a climbing support can encourage larger leaf size and a more upright growth habit.
• When should I repot?
  Repot every 2–3 years or when roots are circling the pot and growth slows despite good care.
