As winter approaches each year, we all become concerned about protecting our tropical plants, especially those which are the most susceptible to cold damage. The fall of 1978 was mild in Tampa, with temperatures seldom reaching below 100C (500F). The mild fall gave many of us a false sense of security and steps for cold protection were put off until "tomorrow". It wa~ this unfortunate procrastination that lead to a premature study of cold tolerance in aroids. My initial idea was to test several landscape and porch plants for cold susceptibility, but unfortunately, I unintentionally tested 46 different aroids.
