One of the tidbits I get from your posts is that it doesn't take many
seasons to select for adapted seeds. This is hopeful, one of the more
hopeful things I've heard lately.
I have no scientific basis for saying this, but my observation is that
plants evolve far faster than animals. Plants are superior survivors and
adapt quickly to new conditions, including your garden, no matter that it
has substantially different conditions than where the mother plants grew.
