Crinum pedunculatum. This White Crinum, or stream lily, is a native Australian plant which can tolerate an incredible range of conditions from dry soils to wet soils or even submerged conditions, and full sun to full shade. However it seems its favorite conditions are lightly dappled shade and submerged in the water.
