Even though Pandanus aquaticus naturally occurs in tropical Australia, it grows well here in the Sydney Gardens alongside the waterlily ponds in a sheltered position. Aboriginal people used the prop roots to make paint brushes and the leaves for weaving and basket making. The seeds of all Pandanus species are edible and were an important food source for Aboriginal tribes. An important plant for stream bank
stabilisation.

Makes an interesting container plant and grows reasonably well in a bright indoor
position.

A beautiful shaped plant in horticulture. Needs full sun and is intolerant of cold.
Propagate from fresh seed.

Not known to be weedy.
