Mimosa problems

Our trip to Starks Nursery went well and we were excited about our pair of Mimosa trees for the front yard.  We looked forward to them gracing the south side of the yard, but they did not survive.  Our good friend, Roy Ratliff, had two more young mimosa trees in his yard and donated them to the Benjamin House.  He even planted them, but they too expired.  Guess it was not meant to be.
