Hi,
This generic name, Dragon Fruit, is used to describe not only species but hybrids between the Hylocereinae species including Epiphyllum.

Other than what I have done I see no suitable alternative.

The photo is of a Hylocereus rootstock with a hybrid scion as it develops.

Cheers

Hi ausrpned, Are you wanting to add a photo of your plant to the database? We currently don't have a general database entry for Hylocereus (at least I couldn't find one) but perhaps the database administrators will add one so you could upload your photo there.

I agree, "Dragon Fruit" is a common name for Hylocereus: https://garden.org/plants/sear... and some probably use that common name for Epiphyllum as well.

"Orchid Cactus" is a common name for a few different genera like Epiphyllum, Disocactus, Selenocereus etc. https://garden.org/plants/sear...

"Queen of the Night" is a common name for a few of the orchid cactus too, as well as the common name of plants in other genera. https://garden.org/plants/sear...

Common names can sure make things confusing.

Here's an entry for Hylocereus.
