Assuming you mean natives, I don't know of any that would thrive in an environment other than a natural one where they were meant to be. Sorry.

lol

they don't have to be natives.

I know all about "cool plants". ;)

What about Colocasia? Pretty easy to overwinter in a nice container indoors, and then move outside when appropriate (or even leave indoors if you want).

:O Wow!! They are pretty I might plant it. Any more?

i like the spiderwort , its really pretty flowers and has like grass like foliage that gets bigger as it gets older. its native to where i live too.

How about some trees? Some that bloom don't get to big, or easy to trim, and some that don't have alot of blooms?(I don't want to be cleaning after my trees any more than, a little over) than needed.
Spiderwort is very pretty, but not what i'm looking for. ;0

Welcome to Gardenweb Goldfishgray! You may want to try the Houseplants forum. I'll link it below. There should be someone there that will know what trees can be grown inside.
Close to the top you will see a list of "related forums" that may be helpful to you.
First, try putting the word "tree" in the search box about 3/4 of the way down the page below. There's another search box at the very bottom of the page that would search EVERY forum instead of just the Houseplants forum so I don't think you want that one. Have fun!

Here is a link that might be useful: Houseplants Forum

thankyou!
