Argyroxiphium sandwicense, the Hawai'i silversword,[1] is a species of silversword. It is endemic to Hawaii. There are two subspecies which are separated by geography.[2] Both subspecies are rare, threatened, and federally protected.

Recent findings[edit]

The Hawai'i silversword flowers only once in its life of 20 to 90 years. It may not survive the ravages of climate change, according to a new study in Global Change Biology.[4]
