A member of the orchid family. These grow wild in my front yard. You'll miss them if you aren't looking for them. They are so tiny! Commonly known as little ladies' tresses or little pearl twist. Native to the Carolinas and Georgia. More info here - http://namethatplant.net/plantdetail.shtml?plant=1951
@corinnec Thank you very much, Corinne. These have grown wild. When I read that there were wild orchids growing in South Carolina, I started looking for some. =) I'll bet there are some where you are too.
@mittens Thanks, Marilyn.
@dutchothotmailcom Thank you, Esther.
