Metasequoia glyptostroboides (Dawn Redwood)
Araucaria heterophylla (Norfolk Island Pine)
Wollemi nobilis (Sort of. I don't have one. They're expensive. They might be really annoying to be around).
Cyptomeria japonicas are also pretty cool. They look kind of like araucarias and there's a billion cultivars.
Any sort of tree fern.
Platycerium bifurcatum (Not hillii. Those are really annoying).
Sansevieras are pretty fun.
Ananas comosus, because they behave predictably and they're pretty easy to grow and start.
Banana plants are also pretty but whether or not I think they're a favorite will depend on how well I can overwinter them here. I mean, lots of people grow bananas in ohio, but that doesn't mean it's EASY.
