Epiphyllum × rollissonii is a historically significant artificial hybrid within the family Cactaceae. Celebrated for its large, vibrant reddish-orange flowers, this epiphytic cactus is a highly sought-after specimen among horticultural collectors 1.

Taxonomy and Naming

The '×' in its botanical name denotes its hybrid origin, created by crossing species within the genus Epiphyllum. The epithet 'rollissonii' pays tribute to the Rollisson nursery, where early hybridization work took place ².

Natural Distribution and Habitat

This plant does not exist in the wild. While wild Epiphyllum species are native to the tropical rainforests of Central and South America, this specific hybrid was intentionally bred in cultivation ¹.

Appearance

It features flattened, leaf-like green stems with undulating margins that initially grow upright before gracefully cascading. The spectacular, funnel-shaped flowers bloom in late spring, often opening at night ².

Care in Cultivation

It thrives in high humidity and bright, indirect or filtered sunlight. Because of its epiphytic nature, the root system requires excellent aeration. Water thoroughly only when the top layers of the soil feel dry ¹.

Common Care Mistakes

Exposing the plant to harsh, direct sunlight causes severe stem scorching. Overwatering combined with dense, heavy soil mixes is the most common cause of root rot.
