Rethinking a Transplant

Update of 08/10/11 — this was a wild plant that a neighbor pointed out to me is invasive.  It certainly grows at a fast pace but hasn’t displaced any other plants.  I decided to let it be.  It gave me this beautiful splash of white for about little over a week in late May/early June.  After that, it kind of died back and took a side seat to some of the other plants around it.  Since it seems to live so peaceably among the others, I have no plans to disturb it.
