I have, what I believe to be, a species of Spiranthes!

I was about to mow my lawn this morning when lo and behold I come across the weirdest looking weed. Its twisted flowers reminded me of an orchid I saw in my "Wild Orchids of South Carolina" book. It suddenly dawned on me that this "weed" could actually be the orchid I saw. I dashed into the house and have been closely comparing the flowers to the ones described in my book. So far, S. vernalis seems the closest based on bloom time, flower arrangement, etc...
I've been travelling for the past 3 weeks, so that is the most viable explanation as to why I'm just now seeing this plant. Usually, my lawn is mowed once a week.
HOW am I supposed to mow now?!?!?
Can anyone else confirm this is S. vernalis, or point me in the direction of a closer species?
