Haleakalā Silversword

Argyroxiphium sandwicense subsp. macrocephalum


A rare plant, part of the family Asteraceae family. The silversword in general is referred to as ʻāhinahina in Hawaiian, meaning "very grey" At senescence, which often occurs when the plant reaches a diameter of approximately 1.6 ft, the plant produces a tall stalk of maroon ray flowers which resemble the sunflower in just a few weeks. Flowering usually occurs from July through October


The Haleakalā silversword is found on the island of Maui at an elevation of 6,900 to 9,800 ft on the dormant Haleakalā volcano — on the summit depression, the rim summits, and surrounding slopes — in Haleakalā National Park.
