This was one of my very first orchids and is pretty close to 30 years old. It has consistently bloomed once a year, but only a few flowers at a time.

The lower stem/roots got very long and dry looking, and the plant top was haning off the side of the pot, so I cut off the worst of it and repotted the green top and left about half the healthy roots running around to suit themselves. It already has new leaves forming and looks good, so I guess I lucked out.
