Species in this genus
The ones growers meet most — each links to its own page.
Selenicereus undatus
Nightblooming Cactus
A climbing succulent epiphyte from Mexico and Central America, this is the dragon fruit cactus, built to drain fast and store water in its fleshy stems. Give it bright indirect light and a gritty, fast-draining mix, and water only when the top two inches have gone fully dry, easing off in winter. As an epiphyte it rots if left sitting wet, so err toward under-watering and let it approach dryness between drinks.
Selenicereus anthonyanus
Fishbone Cactus
Selenicereus anthonyanus is a succulent epiphytic cactus from the forests of southern Mexico, growing on tree branches with flattened, deeply notched stems rather than in soil. As an epiphyte it wants fast-draining, airy mix and good airflow, and its succulent stems store water, so let the top inch or two of mix dry before watering again. It tolerates brief dryness far better than sitting wet, which causes rot.
About the genus
A genus-level overview — shared traits, history, the botany that ties these plants together — is on its way. For now, the species and cultivars above and below carry the genus.
Kept true by its growers
Selenicereus keeps evolving — species move, cultivars appear, IDs get corrected. If you can place an unplaced plant or add a species we’re missing, the whole genus gets truer.
