I live in nw florida, zone 8 and have many volunteer plants with no runners that grows less than 3' tall, has very little fragrance and is very sturdy and gets no attention other than water. No gardener I know has a name for it and I would like to be able to tag it with a name. I am uploading a picture taken last week. so far it has not spread out of the bed where it appeared during the past few years.
