In general, I couldn't agree more with what Bruce said. I find most all orchids, less than stunningly beautiful when not in bloom, very interesting growth, but not beautiful. I do like to try and keep obvious problems off foliage, (sunburn, insect damage, ect.) But some, such as Zygopetulums and Oncidiums are rarely going to have 'showroom new' looking leaves! My favorite orchids by far are the Cattleya alliance, and most all of them are less than beautiful, if not downright ugly, when not in bloom, but I still find their growth fascinating and wait patiently for that sheath that may actually have a bud or two in it!
