I grew this from a cutting from my friend in SC. It was years ago and this is the first bloom on the end of a very long (five ft.) stem. It is so beautiful I would love to have a name for it. I have no idea how to tell all those white epis apart.
If anyone can help me I would be eternally grateful.

Looks very much like Epiphyllum strictum to me. Goes also by the name Epiphyllum phyllanthus var hookeri. This one has very pointy petals.

Absolutely wonderful. Thank you. I noticed it is closed now and the article says it is nocturnal. So I am sure that is what it is. I am so happy to know it has a name. You are wonderful.

You are very welcome!

Try to catch it when it flowers again...wonderful scent....

My message to you did not show up on my computer. This is the second time I lost a post. I wonder what is happening? You saw it because you answered it. Mystery????

This last one showed up. I went out and smelled it and there is no odor at all.

Did you smell it in the evening? I've grown it for 30-some years and mine are always scented...e. strictum....clean, fresh scent.

My e. strictum.....



I don't know if there may be others similar to strictum, but having no scent.....

It was closed and had some bugs on it but I tried to smell what I could and there was no odor. I have a great sense of smell and honestly, no odor. Sorry.

The smell will be gone by the time it is closed and done. At that point there would not be a need any longer to lure a pollinator with a nice scent....

Looks just like my Epiphyllum hookeri: Hooker's Orchid Cactus (Epiphyllum hookeri)

Forgot to add: E. strictum is a synonym for E. hookeri: http://www.theplantlist.org/tp...

Thank you. This is so helpful.

You are quite welcome. It's a lovely bloom! I'm not sure if my plant is still alive ... it's planted in the ground at our other house and I haven't been over there in two years so I'm not sure if it's survived our tenants who are not gardeners.

Not a good thing. If it is dead, I will be happy to give you a chunk of mine.

JB: Oh, that is so sweet and generous of you to offer but I already have so many plants and not much space! Thank you for offering though.
