When I saw it the first time, I didn’t even know Haleakala Silversword is a rare plant and it has been listed as an endangered species. In Haleakala National Park, Silversword can be seen at elevations above 7000ft.
The summit area of Haleakala is hostile to plants. There are only very limited number of brushes or shrubs. However, in this rocky and wind-blasted desert, Haleakala Silversword thrived. The plant has numerous sword-like succulent leaves covered with silver hairs. Its skin and hairs are strong enough to resist the wind and freezing temperature of this harsh environment.
I have seen a lot of Silversword while I hiked the park. However, I have only found one with flowers!
