Often called Pandanus Palms, these plants are not closely related to palm trees. There are about 600 species of Pandanus in the world, and different species vary in size. They commonly have a broad canopy and heavy fruits, leaves and branches which is why they often grow large prop roots to support all that weight.
Uses of Pandanus Fruit and Leaf in Australia Pandanus plants are either male or female plants. They have large fruit that turns gradually from green to red as they mature. The fruit is eatable in many species and Aboriginal People used pandanus fruits as medicine and food. Pandanus leaves are heavy and strong, and were also used by indigenous people for clothing, fishing and as decorations. Animals like bats, crabs and rats are also known to eat Pandanus fruit.
