Yesterday I noted a S. flava 'copper top' had a large tear in the pitcher and strings of living tissue were hanging off. I concluded it as just an odd happening. When I woke up this morning my S. leucophylla 'hot pink's largest pitcher also had this same exact effect. It is like a quarter inch wide tear that goes quite aways along one side of the pitcher, at least 12 inches down the pitcher from where it started. What could be causing this? Anyone have any ideas?
