Appearance
It is an upright perennial which may reach 1–3 m in height. It has long pointed leaves, with heavily-scented white flowers with yellow bases. In its native environment flowering occurs between August and December.It is typically found growing in the forest understory, where the pseudostems arise from rhizomes below ground.
Naming
Beyond its native range ''H. coronarium'' may be invasive in shallow water systems, along streams and in waterlogged areas. Once established, it is difficult to control due to vegetative reproduction through the underground spread of rhizomes. It was introduced in Brazil in the era of slavery, said to have been brought to the country by African slaves who used its leaves as mattresses, and is now considered naturalised in the states of Rio de Janeiro , Bahia and Espirito Santo. This species was first introduced as an ornamental to Hawaii around 1888 by Chinese immigrants, and is now considered a serious invader in mesic to wet areas of Maui and Hawaii island. Additionally, it is invasive in South Africa, where it is a declared weed, and propagation of plant material is considered prohibited. It is also invasive in New Caledonia.
