Night Blooming Cereus
An acquaintance graciously gave me a division of her Night Blooming Cereus last year and it bloomed beautifully.
I am presently overwintering it in the house for next summer.
The only problem is when I went to look it up in my Garden Encyclopedia, there are about a thousand different plants called "Night Blooming Cereus".
Is there any way of figuring out specifically which one it is?
