Story: "An elderly female comes to the Emergency Department complaining: "I got the green vines in my virginity." The patient reports a two-week history of a vine growing from her vagina. On physical examination it is discovered that she does indeed have a vine growing out of her vagina, about six inches in length. A pelvic exam reveals a mass which is easily removed from the vaginal vault, vine still attached. Upon extraction, the patient reports that her uterus had been falling out and that she "put a potato in there to hold it up" and subsequently forgot about it."
Bayblab verdict: The story seems to have many variants on the web, so there may be a lot of embellishment. I have no doubt that someone out there has used a potato as a home remedy for prolapsed uterus. I have seen some weird stuff when i was hanging out in OB/Gyn but I'm not sure anything could germinate in the acidic environment of the vagina ~pH 4.0 . Perhaps we could test whether a potato would grow at that pH.
