Orchid's a-bloomin'

Three or four years after I got it after watching Adaptation and reading The Orchid Thief, my orchid's finally blooming again. I have no idea what if anything I did to get this to happen. I simply water the thing once every week or two.



But the stem with the blooms on it is so much shorter than the one that was on it when I got it? Anyone out there understand this?
