Japanese knotweed or Polygonum cuspidatum

Here is one more species, apparently offered for sale, sometimes included in 
lists of huge plants or "architectural plants."  Giant knotweed or Fallopia 
sachalinensis.  This, indeed, stands out in a group with leaves nearly one 
foot long.  It also has wider or heftier stems.  I meant to mention 
sachalinensis in the earlier post.  You would be attracted to this plant as 
you would to a Hosta with huge leaves.  The roving ways are the same as the 
common knotweed, a giant sized big brother.   Both of these plants are found 
with cream or white edges making them appear to be garden varieties.
