Mystery solved

Had this beautiful mystery blossom growing out on a trail on our property...I knew I ad never planted anything like it in the past 17 years since we have lived at the property...Well, thank goodness for Facebook....
My neighbor happily told me it was a volunteer from her property known as Lychnis Coronaria
Looks like I will be moving some a little closer to the house to enjoy the vibrant electric  pink blossoms. I found detailed information on saving seeds over at Defining Your Home, Garden and travel
