Angraecum magdalenae. Can take cooler temperatures in the winter and can take hotter temperatures in the summer, easy to grow, can spend its entire life in a six-inch pot, doesn't get huge, can take high light or shade. Through everything, it does enjoy its water, even in the cooler temperatures.
The flower lasts a very long time and is fragrant during the day and more so at night. Blooms twice a year.
Note: I grow this in red lava rock and a six-inch basket pot.

I nearly forgot....Angraecum Leonis is very, very easy. I usually forget I have the two of them because, well, they are so undemanding. These are smaller than the mag and easier to find. I have no idea what their light requirement is, though. They seem to grow wherever I put them for the summer or winter. The blooms are a bit more fussy...when the buds get a certain size, they need a little more humidity (but you can't get them wet).
I grow these in very small net pots/LECA with a little moss on top.
They are fine with cooler winter temperatures and hot summers, too. The mag can take full sun but I am not so sure about these.
