Office plants help [View all]

I like to have interesting plants in my office and I'm now in an office that I will be in for the next 8 years.

It has one tall window (6 feet H x 4 feet w x 1 foot deep sill) that gets afternoon light. The building is set at 74 degrees and very constant.

I need suggestions for something interesting and by interesting I mean I'm open to unusual, but the climate is limiting.

Any suggestions?
