Are there any tomato breeds that are more resistant than others

to being perennial, even if their fruit were kind of small, or
berry-like?

That way they'd almost count as perennials.


The Russian tomato varieties do better in cool weather. Look at the
Territorial Seeds website -- they sell a bunch of Russian varieties.

Also, if you live near the coast, composting seaweed right on your garden
beds will lower the temp that plants can survive by a few degrees. Or
buy kelp fertilizers. (If you can get actual seaweed, you don't need to
hose the salt water off it. Just layer it on your beds and let it rot or
dig it in, or mulch the beds in the fall with it.)
