LF specific fic, either Gen or Sam/Dean, w. evil shrubbery

[de_nugis]

This is a long shot, but maybe someone will know what I am talking about. I think it was already old when I read it a year or so ago -- could date back several years.  All I have is evil shrubbery, boys were hacking it down and I think it reappeared the next day or something, I believe it was Bobby who found them the case or was somehow involved. I think it was wincest, but it could have been Gen, and the mood was pretty light.

Sorry to be so vague, but will be most grateful if it gets found.
