Silver Dollar Vine
Xerosicyos danguyi
The Xerosicyos danguyi, or Silver Dollar Vine, is a captivating Madagascan succulent known for its distinctive coin-shaped leaves. These thick, silvery-green discs grow along slender, climbing stems that use delicate tendrils to find their way up supports. Its architectural form and ethereal color make it a favorite for modern interiors, acting as both a living sculpture and a conversation piece. While it evokes the appearance of a delicate vine, it possesses the hardy, water-storing resilience of a desert-dwelling succulent.

Care Guide
Care Guide for Silver Dollar Vine
Light Requirements
Place your Silver Dollar Vine in a spot that receives bright, indirect light for at least 6 hours a day. It can tolerate several hours of direct morning sun, which helps maintain the tight spacing between leaves. If the vine becomes 'leggy,' it needs more light.
Watering Strategy
This plant is highly drought-tolerant. Only water when the potting medium is dry from top to bottom. When watering, saturate the soil until water drains from the bottom, then discard excess water. Never let the plant sit in standing water.
Soil and Drainage
Use a gritty, well-draining substrate. A mix of cactus soil and inorganic material like pumice or perlite works best. A terracotta pot is highly recommended to help moisture evaporate and prevent root rot.
Seasonal Care
During winter dormancy, reduce watering to once every 4-6 weeks, providing just enough to prevent the leaves from shriveling completely. Ensure the plant remains in a warm spot above 60°F (15°C).
