Sounds fishy to me. I doubt if the iron content would be high enough and
it certainly would not form a continuous "wire" as in a lightening rod. 
Also the plant tissue would not be insulated from the iron so I would
expect that the plant would be fried. If it was true then someone should
have a video of a tree being hit by lightening and surviving unharmed.If
such a spectacular video existed, it would certainly be shown on the TV
news and PBS.
