All of the species are evergreen trees that range in height from 20 to 60 metres tall and are found exclusively in relatively moist areas with little or no water stress. There are between 8 and 10 species within the genus depending on the authority, with 4 occurring in North America and 4 to 6 in East Asia. Many species are utilised in horticulture and numerous cultivars have been developed for use in the garden.
