Hi all,

If I am not mistaken, most of the P. americana rootstock is grown via seed.  
Unless the seed is collected within a stand of other P. americana trees, the 
seed would have a pollen parent other than P. americana.  This would make 
the resulting seedlings highly variable in their characteristics and 
performance.  It is difficult to make a true assessment when everyone's 
experience is stemming from the fact that they all have different 
rootstocks.
