Genus guide

Selenicereus — 13 species

Selenicereus is a genus of climbing and sprawling cacti found across tropical America, spanning night-blooming Moonlight Cactus species and the widely cultivated Dragon Fruit vines (including red-fleshed and yellow-fleshed types). They need bright light — ideally several hours of direct sun — and very infrequent watering; allow the soil to dry almost completely between sessions, as wet roots rot quickly. Pet toxicity varies across the genus: dragon fruit species (Selenicereus undatus) are non-toxic to cats and dogs, but not all species have been individually assessed, so verify before buying.

Selenicereus — frequently asked questions

Are Selenicereus plants toxic to cats and dogs?

Most Selenicereus are pet-safe. Of the 13 Selenicereus species we cover, 12 are non-toxic on the ASPCA list and 1 carry a toxic or mildly-toxic rating. Even so, confirm the individual species before trusting it around pets.

How much light do Selenicereus plants need?

Most Selenicereus do best in bright indirect light. If yours stretches toward the window or loses its variegation it wants more light; scorched or bleached leaves mean it is getting too much direct sun.

Are Selenicereus easy to care for?

Selenicereus are moderate to grow: the main requirement is a genuinely bright spot out of harsh midday sun. Get the light right and the rest of their care follows.

How many Selenicereus varieties are there?
