The Enchanting String of Nickels: A Deep Dive into Dischidia nummularia
Dischidia nummularia, affectionately known as the “String of Nickels” or “Button Orchid,” is a captivating epiphytic plant that has garnered significant attention among houseplant enthusiasts. Its unique, coin-shaped leaves and trailing growth habit make it a visually appealing addition to any indoor garden. This article delves into the various aspects of Dischidia nummularia, covering its origins, characteristics, care requirements, propagation methods, and common issues.
Origins and Natural Habitat
Dischidia nummularia belongs to the Apocynaceae family, a diverse group of flowering plants. Native to Southeast Asia, particularly regions in New Guinea, Australia, and surrounding islands, it thrives in warm, humid tropical rainforests. In its natural environment, it grows as an epiphyte, clinging to the branches and trunks of trees, receiving filtered sunlight and moisture from the surrounding air. To better understand this plant, considering the natural habitat is key.
Epiphytic Nature

Epiphytes are plants that grow on other plants, but they do not derive nutrients from their host. Instead, they obtain moisture and nutrients from the air, rain, and debris that accumulate around them. This adaptation allows them to thrive in the canopy of rainforests, where sunlight is abundant.
Understanding this epiphitic nature, is very important to replicating ideal conditions when growing Dischidia Nummularia in home environments.
Characteristics and Appearance
The defining characteristic of Dischidia nummularia is its small, succulent-like leaves. These leaves are typically round or slightly oval, resembling coins or buttons, which explains its popular nicknames.
Leaf Morphology
The leaves are thick, fleshy, and often exhibit a grayish-green hue, giving them a subtle, muted elegance.
Their succulent nature allows them to store water, enabling the plant to withstand periods of dryness.
The small leaves are normally around the size of a small coin.
The leaves are often arranged in opposite pairs along the vining stems.
Growth Habit
Dischidia nummularia is a trailing vine, making it ideal for hanging baskets or displaying on shelves where its cascading stems can be admired.
The stems can grow to significant lengths under ideal conditions.
It’s growth habit lends itself well to indoor home decoration.

Care Requirements
Caring for Dischidia nummularia requires a delicate balance of providing adequate light, moisture, and ventilation.
Light
This plant prefers bright, indirect light. Direct sunlight can scorch its leaves, while insufficient light can lead to leggy growth and reduced flowering.
An East or North facing window often provide ideal conditions.
Filtered sunlight, such as that through a sheer curtain, is also appropriate.
Watering
As an epiphyte, Dischidia nummularia prefers to dry out slightly between waterings. Overwatering can lead to root rot.
Allow the top layer of soil to dry before watering again.
In humid environments less frequent watering is required.
Using well draining soil is very important.
Humidity
High humidity is essential for the healthy growth of this plant. Regular misting or placing it in a bathroom or kitchen can provide the necessary moisture.
Placing the plant on a pebble tray filled with water can help to increase ambient humidity.
Humidifiers are also a great tool to help regulate humidity.
Temperature
Dischidia nummularia thrives in warm temperatures, typically between 65°F and 80°F (18°C and 27°C).
Avoid exposing the plant to cold drafts or sudden temperature fluctuations.
Most normal household temperatures are fine for this plant.
Soil and Potting
A well-draining potting mix is crucial to prevent root rot. A blend of orchid bark, perlite, and sphagnum moss is ideal.
Terracotta pots are suitable, as they allow for better air circulation and drainage.
Due to the epiphitic nature of this plant, it will thrive in mediums that are not normally used for traditional house plants.
Fertilization
Light fertilization is sufficient for Dischidia nummularia. A diluted liquid fertilizer can be applied every few weeks during the growing season.
Avoid over-fertilizing, as this can damage the roots.
Fertilizing should be reduced during the winter dormant season.
Propagation Methods
Dischidia nummularia can be propagated through stem cuttings or leaf cuttings.
Stem Cuttings
Stem cuttings are the most common and effective method of propagation.
Select a healthy stem and cut it into sections, ensuring that each section has at least a few leaves.
Allow the cuttings to callous over for a day or two before planting them in a well-draining potting mix.
Maintain high humidity and provide bright, indirect light until the cuttings root.
Leaf Cuttings
Leaf cuttings are possible but generally slower.
Select healthy leaves, and remove them from the stem.
Allow the leafs to callous over before planting them in a very well draining mix.
Maintain high humidity.
Common Issues and Solutions
While Dischidia nummularia is generally a resilient plant, it can be susceptible to a few common issues.
Root Rot
Overwatering is the primary cause of root rot. Ensure that the potting mix is well-draining and allow the soil to dry out between waterings.
Provide adequate drainage.
Pest Infestations
Mealybugs and spider mites can sometimes infest Dischidia nummularia. Regularly inspect the plant for signs of pests and treat them promptly with insecticidal soap or neem oil.
Good air circulation can help to prevent pest infestations.
Leaf Drop
Leaf drop can occur due to insufficient light, overwatering, or sudden changes in temperature or humidity.
Adjust the plant’s environment to address these factors.
Lack of Flowering
Inadequate lighting, or nutrients, can prevent flowering. Ensure the plant is recieving proper care.
Enhancing Indoor Decor
Dischidia nummularia’s aesthetic appeal makes it a versatile addition to indoor decor.
Hanging Baskets
Its trailing growth habit makes it perfect for hanging baskets, where its delicate stems can cascade down, creating a visually captivating display.
Shelves and Plant Stands
Placing it on shelves or plant stands allows its unique leaves to be showcased, adding a touch of natural elegance to any room.
Terrariums
The plant can also thrive in terrariums, providing proper humidity, and air circulation is maintained.
Concluding Thoughts
Dischidia nummularia is a delightful and rewarding plant to cultivate. Its unique appearance and relatively easy care requirements make it a popular choice among houseplant enthusiasts. By providing the right conditions, you can enjoy the beauty of this enchanting “String of Nickels” for years to come.
