This post is for future reference; I know I can't grow any exotic fruit trees where I live, temperature is too cold.

Can anybody please refer me to sites that have exotic fruit trees?

The main type of fruit trees I'm looking for are.....

kumquat

dragonfruit

papaya

I've had a very difficult time locating sites that sell

dwarf exotic fruit trees; yes I've looked through the internet...via various search engines.

Also with the type of fruit trees listed above, can they be grown outdoors (without protection, like a normal fruit tree).

Zones they'd be grown in would be zone 9 or 10.
