Hedychium coronarium is an aquatic macrophyte considered an alien and invasive plant outside the Himalayan region, its dispersal center. It was introduced in the Americas, occurring in different regions in Brazil, including the Tripuí Ecological Station (EET) in Ouro Preto-MG. This plant has negative effects on regional biodiversity, thereby studies on its phenological and ecological aspects are needed to assist in control and management measures. Aspects such as height growth, flowering, fructification and stem duration were evaluated between August 2002 and July 2003 at different EET areas. Areas with shade between 60-80% allowed better height growth and fructification. These areas require more attention in management and control.
