The genus Epiphyllum includes a group of cacti that are usually epiphytic, meaning they grow on other plants, typically trees, in tropical and subtropical regions. Unlike desert cacti, they thrive in humid, shaded environments. Think of them as the orchids of the cactus world. They are known for their large, showy flowers that often bloom at night. Their stems are flattened and leaf-like, giving them a distinctive appearance. Epiphyllums are popular as houseplants due to their ease of care and stunning floral displays.
