What type of leaf does the grass tree have?

Grass trees, belonging to the genus Xanthorrhoea, have long, strappy, and narrow leaves that grow in a tufted form at the top of a tall, woody trunk. These leaves are typically rigid and grass-like, often appearing dark green or sometimes grayish. They are well-adapted to withstand drought and fire, which are common in their native Australian habitats. The leaves can grow up to several feet in length and are known for their unique appearance and resilience.
