Epiphyllum is a genus of cacti known for their stunning, large flowers and unique growth habit. Commonly referred to as "orchid cacti," these plants typically grow on other surfaces, such as trees, rather than in soil. They thrive in tropical and subtropical regions, making them popular houseplants in many areas. The flowers of Epiphyllum can be quite spectacular, often blooming at night and emitting a sweet fragrance. These blooms come in various colors, including white, pink, and red, and can last for just a single night. Epiphyllum plants are relatively easy to care for, requiring bright, indirect light and well-draining soil.
