Disocactus speciosus, commonly known as the Candle Cactus, is a perennial epiphytic succulent native to the tropical rainforests of Mexico. It is often found growing on trees or rocks in its natural habitat, where it receives dappled sunlight and has excellent drainage due to its epiphytic nature. This species typically reaches a height of 1-2 feet (0.3-0.6 meters) and has a cascading growth habit, making it an attractive hanging basket plant. The Candle Cactus is renowned for its vibrant, trumpet-shaped red flowers that bloom in the spring, providing a striking display against the green, leaf-like stems.

The Candle Cactus is valued for its ornamental flowers and ease of care, making it a popular choice for indoor cultivation or sheltered outdoor environments in warmer climates. It is often used in hanging baskets or as a container plant on patios and balconies. In cultivation, it requires bright, indirect light or part shade, well-draining soil, and moderate watering, allowing the soil to dry out slightly between waterings. Overwatering can lead to root rot, so proper drainage is crucial. While it is generally pest-resistant, mealybugs and scale insects can sometimes be a problem. To encourage blooming, a cooler and drier winter rest period is beneficial.CC BY-SA 4.0
