Tarev touched on something I'd forgotten to mention that I'd meant to. Winter bloomers!
Holiday cacti (and other assorted epiphytes)
various Kalanchoes
good ol' wax Begonias
Callisia fragrans (basket plant, as the species name indeed indicates, it's *fragrant.*)
African violets can bloom any time.
(But avoid any you find boring without flowers - so you don't just dislike them for the other 10+ months of the year.)
