Few people realise the intense, convoluted and internecine controversies that rage in the world of vegetable folklorists. These dour scholars generally gather in the darker corners of academe, preferring potting sheds and greenhouses to the more usual bars and senior common rooms frequented by their colleagues. They putter about in the basements of libraries where more mainstream scholars fear to tread, seeking out old manuscripts and botanical treatises. Some of them roam the highways and byways of obscure rural districts, seeking undiscovered nuggets of folklore and superstition. These solitary pursuits result in impassioned debate when these normally taciturn scholars meet.
