It's the variety you got. It is bred to bloom like this.

smwboxer: you're saying this variety was bred to have just one spike, out of the 7 or 8 in the time that I've had the plant, bloom this way!!?? I'd like to meet the hybridizer who achieved this feat.

I have reposted this question in the orchid forum with link to photo. thanks

Sorry, you original top post was not clear on that. Sorry for giving my opinion. I will make sure not do so again.

In the genetic make-up of a number of orchids, Anguloa clowesii, springs to mind, there is an inbuilt mechanism which tells the flower not to open fully. There are a number of possible reasons for this. In the case of Phalaenopsis this is not usually present, but cross-breeding may be at fault here.

i kind of wonder wgat would happen if you got theis certain spike to produce a keiki... on rare occasion a plant will have 1 part of the plant that will have a genetic nutation thats not present in the rest of the plant (which is how the washington oranage came to be)maybe this is the case with your phal. i wonder if you were to make it produce a keiki, would the flowers off of the F2 plant stay somewhat closed as this spike is doing now....
