Looking at where you live - if you are looking for one of the easiest Orchids to bloom, pick a FALL- flowering Cattleya ( C, Blc, Bc, Lc...).
Grow them outside over the Summer, watch them put on growth, water and fertilize while outside with the rest of your stuff and enjoy the Orchid putting on a show in the Fall.
If not in bloom when you purchase the plant, the Vendor can tell you when it blooms!
