The Haleakala Silversword
(Argyroxiphium sandwicense ssp. macrocephalum)
Silverswords are indigenous to Hawaii. These rare, exotic plants are found on the top of Haleakala volcano in Maui. Named for their sharp 'sword like' leaves, they are light green color, with a fine silver hair that reflect as silver shards in the sunlight.
The life span of a silversword is between six and fifteen years. They flower in the summer months, showcasing hundreds of flowers on a elongated stem towering above the 'body' of the plant. Haleakala silverswords are protected in Hawaii, as they are listed as a threatened species due to risk of extinction.
