Some years ago when I was in the Austin area of Texas I think I saw some
banana plants growing in some people's backyards. They will probably grow
in warm microclimates like close to south facing walls. Have no idea what
varieties are hardiest.
Texas seems pretty dry. I think that availability of water would be more
the limiting factor on food production of that region rather than the
availability of land. Water can be pumped from aquifers, of course, but
that can also be overdone and requires energy for pumping. I've heard
people say that Texas can accomodate a much larger population, but I think
they are wrong and it's probably over its carrying capacity already if you
consider the availabilty of water.
