Thank you for your help. I will check one in the morning and try to pull a plant out so that I can get a photo of its roots. I do not ever recall seeing any type of nodes on the root structure so I am not sure about the it being C. benghalensis but I will double check. The house where it grew "naturally" was built in the 50's and my folks were the second owners on record. Many of their neighbor's were the original purchasers of their homes and none of them knew what this was nor did they have it growing in their yards. This makes me wonder if the original owners of my parents' home did not bring the plant with them when they moved in or perhaps were given a cutting at some point in time. If so, it would open up the geo location possibilities.
Again, thank you so much for all of the assistance. It is most appreciated.
