Argyroxiphium is a small genus of plants in the sunflower family, Asteraceae. Its members are known by the common names of silversword or greensword due to their long, narrow leaves and the silvery hairs on some species.

The Silversword plant grows only at high elevations on the Island of Maui in Hawaii.

It is a noticeable, round-shaped rosette plant with rigid (swordlike), succulent leaves densely covered by silver hairs. When a plant flowers at the end of its life, it produces a spectacular flowering stalk 0.5-2.0 m (1.6-6.4 ft) tall, typically with hundreds of maroon sunflowerlike flower heads. This plant receives more attention from visitors to Haleakala National Park than any other plant or animal because of its striking appearance and restricted distribution.
