The first picture is taken in late July of the plant at the edge of a brush pile. The other pictures are taken of the same plant in a grown up garden area in Irmo, SC.
Hi Dennis,
your plant is Heliotropium indicum, the Indian heliotrope. It is very widespread and has had many uses. The internet will expand on this. The flower spike is referred to as ‘scorpioid’ meaning it is curled at the end like a scorpion tail.
Sincerely,
Dr. Steven Hill, Botanist, SCNPS
