Phal's Double bloom spikes - question

[quietmorning]

My daughter sent me a Phal for mother's day. I was looking at the web site where she purchased it, and they sold phal's with one bloom spike, two, or multiple - excuse me while I show my ignorance. . .is this a species type or do all phals grow more than one spike eventually?

I've never owned an orchid long enough and was successful enough to get more than one spike to grow - so is this care. . .age. . .type?

Thanks!
