The ecological factors and mechanisms that determine the bioinvasion success of exotic plant species have become a cause celebre in current ecological research as witnessed by the many leading hypotheses and articles published. In pursuit of understanding invasive plants, while mining the Global Invasive Species Database, we found that a large number of invasive plants are characterized by flower colour polymorphism and multi-seasonal flowering. An effort has been made here to find out if these two traits have any role in invasiveness in plants.
