Friday the 13th has just passed and in some sort of dyslexic dystopia, the 31st is just around the corner and Halloween will soon arrive. So it seems only right to write of that which is wrong - or shall we say – wicked, as in Wicked Plants. There is an excellent book by just that title, “Wicked Plants: The Weed That Killed Lincoln’s Mother and Other Botanical Atrocities” by Amy Stewart. I recommend it, but for now, let us take a little trip into the world of some plants wicked this way come, through the house of horticultural horrors, guided by myself, and fellow OSU-Secrest Arboretoids, Paul Snyder, Joe Cochran, and Matt Shultzman.
