Daethen, since I'm new to orchids (about 1 year) and am a windowsill grower, I stick to the more common genera. My most "exotic" orchid is a Psychopsis.
I also buy only plants in low spike or bud, if I can't get it to bloom in the future, I've at least seen the flowers once.
I never buy seedlings. At my age, I can't afford to wait for years for flowers.
So this should give you an idea what I'm bidding on.
Right now I am after Tolumnia, they are cute, pretty, don't take up much space and do well for me.
