Probably the easiest are those that do not require any kind of a dormancy [or rest] period. Ones which instead like warm moist conditions all year round.
Drosera [sundews]: some good candidates: D. capensis, & D. spathulata
lowland Nepenthes: such as N. gracilis, N. ventricosa, N.ampullaria
***be forewarned that pretty much all the neps will at some point outgrow a small terr [15 gal or less] - and most rather quickly [w/in a year or two].
Pinguiculas [butterworts]: ex. P. primaflora
Sarracenia [terrestrial pitcher plants]
***same problem as w/ neps
