I really liked this geranium. It grew well for me in my zone 3b garden. Unfortunately it succumed to a dose of Round-Up when my wife was attempting to kill some thistles and drift from the spray was enough to kill it. I have been looking for another one like this and I am willing to purchase seeds if necessary to propagate it. Does anyone know where the seeds can be purchased from? Kindly email me at: djk1948@hotmail.com with the information.
Thank you.
