This is my mother-in-laws plant, and don't even know where to start. Now that we have brought the plant inside it has been growing the long green stems and they are almost to the ceiling. Please help, thank you.
Possibly Epiphyllum oxypetalum (Queen of the Night) which is an old pass-along type epiphytic cacti houseplant.
Have you ever seen it bloom? Does it bloom at night?
No it does not bloom.
The stems on mine got 3 feet long before it bloomed.
I was just thinking it was about time for another query about this plant - which it definitely is.
