Large white moth orchid flower

What is not to like of an ever-blooming orchid? This is one of my most floriferous orchids, which sports huge 5 inch blooms most of the year. Surprisingly, this moth orchid has been re-blooming on 3-4 year old spikes while being so pot-bound most of the roots are hanging outside of the hanging pot. 
This is one of my first orchids in my collection.
