Night-blooming Cereus: Types, Care, and Cultivation

Spread the love

Night-blooming cereus is the common name for several species of flowering ceroid cacti, usually possessing short-lived flowers that bloom at night. These plants bloom once a year and produce beautiful, often fragrant flowers that open after nightfall and last only for a single night.

While the name “cereus” is often associated with these plants, it is not limited to the Cereus genus. There are actually multiple species from different genera that fall under this category, including Cereus, Epiphyllum, Hylocereus, and Selenicereus.

The reason why night-blooming cereus is often thought of as a single plant is due to the confusion with the common name. The problem with common plant names is that the same name can mean different plants in different areas such is the same with Bird of Paradise.

Common names often group together different species or varieties that share similar characteristics or habits. And while the is the name “Cereus”, the term “night-blooming cereus” is a catch-all phrase that encompasses various cacti species that share the characteristic of blooming at night.

What are the bloom characteristics of a night-blooming cereus?

Night-blooming cereus plants typically bloom in stages, with the flowers opening gradually over the course of several hours. The flowers usually begin to open in the evening and continue to bloom throughout the night, with the peak bloom occurring in the early morning hours. The flowers typically last for only one night before wilting and falling off by dawn.

During this nocturnal flowering, these fragrant flowers attract moths, butterflies, and bats who come to savor the nectar and promote pollination.

Night-blooming cereus flowers are usually white or pale shades of other colors, often large, and frequently fragrant. Plants in the same geographical area tend to bloom on the same night, and healthy plants may have multiple blooming events spread over the warmest months
