Hi, I have been working with my epi's and I have some of the epi oxypetalum, e. strictum and e. hookeri. Are these all the same plant just with different synonyms?
Thanks a bunch,
Linda

Oxypetalum is different from the other two you mentioned, but the strictum and hookeri are the same thing. Hookeri/strictum seems to be more temperature sensitive here..meaning I don't keep it in the cool greenhouse with the others because it tends to crash when temps get below 40. It has a place in the house for the colder months. Hope this helps.

Hookeri has many Synonym(s): Cereus hookeri, Phyllocactus hookeri, Epiphyllum phyllanthus, Phyllocactus stenopetalus, Epiphyllum stenopetalum, Phyllocactus strictus, Epiphyllum strictum. Epiphyllum Strictum and Hookeri are the same and are in the same family as Oxypetalum. All are night bloomers and come from the tropics: Cuba, South and 'Central America, etc. While Oxypetalum has a bell shaped bloom, Hookeri (Strictum) has a daisy shaped bloom. I will show pictures of both. These are true epies while the hybrids we all love are not. Strictum has longer, narrower stems than does Oxypetalum. In my collection, I call Strictum Aster Strictum rather than Hookeri Strictum. A lot of collectors are trying to get examples of all the named synonyms for their collections.

Orchidman, thank you so much. I have some of both and I need to cut some back ( to fit in the greenhouse). I may print out your pics and answers so that I can compare them outside.
Have a great weekend,

Thanks for asking this question, Linda. I was wondering the same when I saw a photo of E. hookeri posted on Facebook and thought it looked exactly like my E. strictum! Nice to know we were neither of us wrong!
My strictum bloomed 5 times this season, and I didn't know to keep it in a warm greenhouse last winter. My GH got down to 36 several times. Perhaps I scared my strictum into blooming with that poor treatment! ;-) It was the only epi that bloomed.

Brenda, I have done the same thing. I may leave mine out too long, but they seem to do ok. Right now I need more space for the cuttings I took. Do you need some more cuttings?

No, thank you, that is very kind of you...
But wow, that zig-zag or ric-rac cutting you sent has the longest "teeth" on it that I have ever seen.
My ric-rac is just a puny little thing in the teeth department!
I hope the one you sent me roots!
Evidently there are ric-racs and THEN...there are ric-racs! LOL! I'm impressed! Surely they can't be the same thing!!!

That particular Ric Rac cacti was about 8 feet in diameter. I had to cut it way back to fit it in my greenhouse. I've never seen 1 that large either.

Just have to share mine. I didnt even know what it was until it bloomed. All I had to do was open the front door to smell it. This was taken on 9-24-11

Just a note on Green House temps for Epies. I keep mine at 38-45 F all winter. This is good for Orchid Cactus. I also have Orchids in with mine at these cooler temperatures and they still do well. The orchids should be kept a little warmer, however! Your main concern becomes fungal diseases and rot in lower temps. I try to spray a fungicide monthly and keep air flow stronger during the winter. bob The attached picture is my GH which is like a chilly jungle right now!

Thanks Orchidman. I am not sure what the temps are running in my greenhouse right now. Our night time temps are still in the 60's with an occasional dip into the high 30's or low 40's. I do have a small heater in there, it is an 8x 24' wooden building, ( but my son uses 1/2 for his art studio and sometimes keeps it steamy) all in all, the plants are basically just in survival mode until I can make other arrangements for them. I will keep track better this winter and see how things work. I cut all of my epis back drastically this fall and have a lot of them rooting. I watered them yesterday and they were looking good.

I use Ortho Daconil 2787 mixing it and adding to misting system on a monthly basis. Whenever possible I use Ortho products in the greenhouse. you really need to be careful when adding chemicals to an enclosed environment.

Space Rocket is beautiful, but I love Mor Mor. I have put it on my list on notepad,of ones to watch for. I can see why you are hooked on those blooms. I have been drooling all over everyone's pics..lol.. I dread waiting 3 years for blooms, but they are definately worth it! I have a couple cuttings that have new growth on them. I get so excited, when I see new growth...it means another one is gonna make it. Epi's are definately a plant for those with patience..lol

If you are like me Brenda you miss them because they bloom at night. I gave a friend part of mine and it bloomed and she took pictures to show me.lol

They must be rootbound. Most bloom at night. The epiphyllum hybrids often bloom during the day, but definitely not until they are rootbound and then it is usually on new growth.
Anyone with better info?

Night bloomers are usually your original plants straight from the lower America's, and the islands. Included: : Cereus hookeri, Phyllocactus hookeri, Epiphyllum phyllanthus, Phyllocactus stenopetalus, Epiphyllum stenopetalum, Phyllocactus strictus, Epiphyllum strictum. Epiphyllum Strictum and Hookeri are the same and are in the same family as Oxypetalum. These are epiphyllums.

Hybrids (breeds derived from these originals), are man made and not epiphyllums, though they are usually called so. They usually bloom during the day and last several days while the original night bloomers only last for a night. There are several thousand hybrids and I recommend joining the Epiforums if you would like to see pictures of most of them ( http://www.epiforums.com/). There is no cost to joining. Your Christmas, Thanksgiving, and Easter cactus belong to this grouping. bob

Thank you Bob I will definitely check into that. There is still so much I need to learn about these plants.
This is my pink one that bloomed in late april. After it bloomed, I found a tag, it said millenium, but then I saw a picture online and it didn't look the same as that one that was listed as millenium. This one bloomed for 2.5 days

This white one bloomed during the day too, but it only lasted 1 day.

I don't think there was ever a tag in this one.

That looks a lot like Epi. oxypetalum. Mine stayed open during the day the first two years from a cutting, then became a night only bloomer. The only other white I have is Epi. crenatum, but both of those have distinctive leaves, and there are a bunch of white hybrids out there that are named.

I can't be certain, but your white bloom above appears to be Epiphyllum thomasianum. Day bloomer in May. I am certain that it's not Oxy. Look at it http://www.epiforums.com/gallery/showimage.php?i=10948&catid=searchresults&searchid=63280
