How a Potato Plant Grows

[NathanP]

Nobody has ever seen such a potato plant as you describe. They simply don't exist. Sort of like the unicorn or philosopher's stone. Never has any meaningful picture been posted anywhere indicating the nonsense propagated by the Seattle Times. People have tried to fudge meaningless photos with a bit of Yankee blarney.

You seem awfully angry about something that you admittedly describe as unprovable.
Just because you have not seen evidence that you would accept as proof does not mean either this is not true, or that evidence does not exist. Lack of evidence for something does not make it false. You're welcome to your opinion on the matter, of course.
