Scindapsus treubii ‘Dark Form’ has become a favored houseplant, captivating enthusiasts with its distinctive appearance. Its deep, rich foliage offers a sophisticated touch to indoor spaces, making it a desirable addition for unique botanical displays. The plant’s striking visual contrast and ability to thrive in typical home environments contribute to its appeal.
Unveiling the ‘Dark Form’
The ‘Dark Form’ cultivar of Scindapsus treubii is distinguished by its exceptionally deep green leaves, often appearing almost black under certain lighting. These leaves are thick, glossy, and typically heart-shaped, contributing to the plant’s lush appearance. Some specimens may exhibit subtle silvery variegation, but its primary allure is the uniform, dark coloration. This dark pigmentation, due to high chlorophyll, allows the plant to efficiently absorb light in its native, often shaded, habitats. Compared to other Scindapsus varieties like ‘Moonlight’, the ‘Dark Form’ offers a more dramatic elegance.
Comprehensive Care Guide
Lighting Needs
Scindapsus treubii ‘Dark Form’ thrives in bright, indirect light. Place it near an east-facing window or a few feet from an unobstructed southern or western window. Avoid direct sunlight, especially during midday, as it can scorch leaves and fade the deep coloration. While it tolerates medium or lower light, growth will be slower, and the signature dark hue may diminish.
Watering Practices
Allow the top inch or two of the soil to dry out completely before watering again. Overwatering can lead to root rot, a common issue for this plant. When watering, ensure thorough saturation until water drains from the bottom of the pot, then discard any excess. It is better to err on the side of underwatering than overwatering for this plant.
Humidity and Temperature
This plant originates from tropical rainforests and appreciates moderate to high humidity, ideally 40-60%. While it adapts to average household humidity, additional moisture can be beneficial. Increase humidity using a humidifier or by grouping plants to create a localized humid microclimate. Maintain comfortable room temperatures between 60-85°F (15-29°C) for optimal growth. Avoid cold drafts or sudden temperature fluctuations, as these can cause stress.
Soil and Potting
A well-draining, airy potting mix is essential for Scindapsus treubii ‘Dark Form’ to prevent waterlogging and promote root aeration. An aroid-specific mix or regular potting soil amended with perlite, orchid bark, peat moss, or coco coir works well. The pot must have drainage holes. This plant is a slow grower, with its root system developing gradually. Repotting is infrequent, typically every two to four years, or when visibly root-bound.
Fertilization
During its active growing season (spring and summer), Scindapsus treubii ‘Dark Form’ benefits from regular fertilization. Apply a balanced liquid fertilizer, diluted to half strength, every 4-6 weeks. This provides necessary nutrients for its development. Reduce or discontinue fertilization during fall and winter when the plant’s growth naturally slows. Avoid over-fertilization, as it can harm the plant.
Propagation Techniques
Propagating Scindapsus treubii ‘Dark Form’ is commonly achieved through stem cuttings. Select a healthy vine and make a clean cut just below a node, which is a small bump on the stem where leaves and aerial roots emerge. Each cutting should have at least one leaf and one node for successful rooting.
Cuttings can be rooted in various mediums:
Water: Submerge the node while the leaf remains above the waterline, refreshing water every few days.
Sphagnum moss
Well-draining soil mix
Roots typically form within a few weeks, after which the cutting can be transferred to soil. Rooting hormone can encourage faster root development.
Common Challenges and Solutions
Yellowing leaves on Scindapsus treubii ‘Dark Form’ often indicate overwatering, which can lead to root rot. This can also be a symptom of insufficient light or, less commonly, too much direct light. Adjusting the watering schedule to allow the soil to dry out more between waterings and assessing light conditions helps resolve this.
Browning leaf tips are less common for this plant, but can sometimes point to very low humidity. Stunted or leggy growth, characterized by long, sparse stems, suggests the plant is not receiving enough light. Relocating it to a brighter, indirect light spot encourages more compact and vigorous growth.
Scindapsus treubii ‘Dark Form’ can occasionally encounter common houseplant pests like spider mites, thrips, aphids, and mealybugs. Regular inspection of the foliage, especially leaf undersides, allows for early detection. Prompt treatment with appropriate pest control methods prevents widespread infestations.
