Wait, you can plant things that are out of your native area? How would they grow? I mean your soil is your soil, right? Unless you're buying soil, that would make sense.
It's really not as strange as it may initially seem considering where tomatoes were natively grown originally (the tropics if I recall correctly),prior to the vast and long lasting domestication and selective breeding that gives us the modern tomatoes that can be successfully grown in much of the world.
I generally have had good luck with cayenne peppers (which are native to the tropics) as an annual in northern Alabama clay/loam (where I'm right on the northern edge of the sub-tropics).
While I can and (have) plant from seeds directly into the ground, it tends to greatly reduce the time I can harvest. Where if I plant indoors earlier in the year and then transplant once it's warm enough I can/have harvested more peppers per plant with more blossom/fruiting cycles.
Still working to iron out my processes, but having harvested multiple gallons from 6 pepper plants that started as seedlings (which were transplanted into containers) I know the weather will permit me to get very large harvests per plant over multiple fruiting cycles during the summer/early fall. I just need to be able to take advantage of artificially extending the growing season. Preferably by starting seeds indoors instead of losing time by directly planting them in the ground after the soil has gotten warm enough to directly seed them into the ground.
So not as huge of a difference in climates as growing fruit citrus trees in the Austrian mountains (
Holzer Fruit Tree System (Sepp Holzer forum at permies) ),but still enough that the extra growing time (or lack there of) can make a noticeable difference.
Of course growing something from a hotter climate in a colder climate is one thing, where growing something from a colder climate in a hotter one is (potentially) a bit more of a challenge. One I haven't really attempted (yet),but as much as I'm started to miss having certain varieties of fruits (varieties of apples being one) I may try it at some point.
