This plant was given to my husband by a professor in the Biology department at UNB. She remarked that it is a cactus, but not a true cactus. It had already bloomed, but there were still 2 buds on it, and when this one opened I couldn't resist taking a picture. Can you identify the plant? Thank you.
Gooseneck cactus (Epipyllum oxypetalum) frequently asked about, possibly it happens to be one of those, or another species (or hybrid, of which there are many) in the same genus - or a related genus, such as Nopalxochia. Another common one is a red-flowered species which has been called N. ackermannii (Epiphyllum a.).
