If you could only keep one orchid...which one?

[Subrosa]

In a perfect world, it would be Cattleya iricolor, hands down. I love the fragrance, and it fills my house like nothing else from late morning until mid afternoon when the plants are in bloom. But this world is not perfect, and those flowers only last a week, perhaps a day or two more. Not a problem at all when it's in the rotation, but if it was the only plant.........I actually prefer the fragrance of my nobilior var amaliae, it fills the room it's in with fragrance, if not the whole house, and the blooms can go over a month. So there it is.
