I agree!
Tara, I do think yours bloomed, you just missed it!! Next time it looks like it did in that picture you posted on the 13., get ready at sundown and watch it open. They're usually fully open around 10 o'clock around here. The only time I ever saw one of those open still at 8 am was on a really chilly morning, it stayed open another half hour and then drooped.
My Epiphyllum phyllanthus is a special case, it did happen more than once that I watched a bud all evening long, even checked on it at night. If it was open bĂȘtween 3 and 4 am I surely missed it. But that one is known to be cleistogamous on occasion, the Epi you posted surely is not.
