[NAFEX] Ernest's Evans cherries

Well, I expect I am mistaken about them coming in true from seed.  I am 
a bit of a novice in this field.

Still, it seemed odd to graft a hardy tree onto a not-so-hardy root 
stock.  The idea that this is to prevent suckering seems reasonable.

I'm near St. Paul, Minnesota.
