Suggestions for first Orchid in non-ideal climates

[Leafmite]

My temps in the winter is set at 64'F but on cold, dreary days and frigid winter nights, the window areas are likely colder. Neofinetia and Burrageara Nelly Isler 'Swiss Beauty' should do well. The first is small and cute but only blooms once a year (some varieties bloom less often) but the Burrageara Nelly Isler 'Swiss Beauty' is an undemanding orchid that would do well with your lighting and tolerates a variety in temperature over 50'F and blooms three times a year for over two months at a time.
