rivers). Folklore Purple panic is a term used by students in south-east Queensland for student stress during the period of late spring and early summer. The "purple" refers to the flowers of Jacaranda trees, which bloom at that time and have been extensively planted throughout that district. The "panic" refers to the need to be completing assignments and studying for final exams. The Jacaranda when in bloom is also known as the exam tree. Conversely, while the time of year the jacarandas bloom in Pretoria coincides with the year-end exams at the University of Pretoria, legend has it there that if a flower from a jacaranda drops on a student's head, the student will pass all their exams.
