String of Nickels
Dischidia nummularia
Updated Jul 26, 2026
String of Nickels (Dischidia nummularia) is a trailing epiphyte with round, coin-like leaves that stays dense in bright, indirect light, high humidity, and a very airy root zone.
About String of Nickels
String of Nickels is a trailing epiphyte with thin stems and small round leaves that look like green coins. The leaves sit close together when the plant is comfortable, giving it a compact, layered look.
It works well in hanging pots, baskets, or mounted displays, where the stems can drape naturally. The plant stays neater and fuller when conditions are stable, especially when the air is humid and the root zone stays airy rather than dense.
String of Nickels does not grow like a typical soil-based vine. Its roots are adapted to fast airflow and quick drying, so it does best with controlled moisture, an open structure around the roots, and protection from both prolonged dryness and soggy, compact mix.
How to Care for String of Nickels
Watering
Keep watering moderate, but only in an airy setup. Water String of Nickels when the top part of the mix feels dry and the pot has become noticeably lighter, then water thoroughly and let it drain quickly.
The goal is a cycle that provides moisture without prolonged wetness, because epiphytic roots need oxygen as much as water. In warmer or brighter conditions, the plant may dry faster and need watering more often. In winter or lower light, extend the interval.
If humidity is low, do not let the plant stay bone-dry for long periods, because the leaves can dehydrate and drop.
Sunlight
Provide medium light, with bright, indirect light as the best fit. An east-facing window or a position set back from strong south or west sun works well for String of Nickels.
Too little light usually leads to thinner growth and wider spacing between leaves. Harsh direct midday sun can scorch or dry the small leaves, especially when indoor air is also dry.
Stable light conditions also help the plant hold onto its leaves more reliably.
Temperature
Aim for moderate temperatures around 64–77°F (18–25°C) with as little fluctuation as possible. String of Nickels should be protected from cold drafts, chilled winter windows, and hot dry air from heaters or vents.
Sudden temperature changes can stress the trailing growth and may contribute to leaf drop.
Humidity
String of Nickels prefers high humidity, and this is one of the main conditions that helps it stay full and compact. In dry rooms, the leaves may shrink slightly, crisp at the edges, or begin to drop.
A humidifier, a bright bathroom with enough light, or grouping plants can help raise humidity. Higher humidity should still be paired with airflow so the stems and crown do not stay stagnant after watering.
Soil
Use well-draining soil that behaves like an epiphyte mix: airy, chunky, and fast-drying. String of Nickels does best when water moves through quickly and the roots stay in an oxygen-rich structure rather than a heavy, compact mass.
An orchid-bark-heavy mix with perlite or pumice and a small amount of potting mix or coco-based material works well for moisture buffering. Avoid dense mixes that stay wet for too long. Drainage holes are essential, and baskets or mounted growing can also work well because they improve airflow.
Pests & Problems
Watch for mealybugs and scale, especially around the nodes and under the leaves. In String of Nickels, leaf drop is most often linked to low humidity, inconsistent watering, or roots sitting too long in a mix that stays wet and dense.
If the plant starts declining, correct the environment first. Increase humidity, improve root airflow, and adjust watering based on how quickly the mix is drying rather than following a fixed schedule.
