Im sure this is E. oxypetalum, and not E. crenatum...but Im no officianado on epis.
Someone gave me this plant in London 30 years ago. I then gave a cutting to a friend here 20 years ago. 3 years ago I took back a cutting. Tonight I have 30 flowers open at once, and it is beyond words to describe. Stunning, and the scent is overwhelming. They only open at night , and tommorrow will all be finished, so photos with flash cant do it justice, but Ive tried. We have many cacti here with similar flowers.....Hylocereus, Selenicereus etc...but to me this plant is less aggressive and more elegant. I just cant wait till I can finish my house and plant it in the ground and let it go wild...:))
Wow, beautiful Epi. oxypetalum Dom. Great growing! Those blooms are really beautiful and there are so many of them! I've had an oxypetalum for years but have never had more than three blooms at once. My plant stays outside year round and when it bloomed last summer I took photo's in the dark by shining a flashlight on the bloom and then snapping the photo.
