Haleakala Silverswords
The luminous Haleakala silversword (Argyroxiphium sandwicense subsp. macrocephalum) can live up to 90 years. It flowers spectacularly once in its life and then dies.

Over 850 species of plants are found within the bounds of Haleakala National Park. Of these, over 400 species are native, or arrived without human intervention; over 300 species are endemic to Hawai'i, found only in the islands.

This astonishing diversity reflects the variety of climates and elevations that allowed plants to fill niches from dry alpine deserts to humid, salt-sprayed coastlines. Plant communities formed in some of the most unlikely dry deserts and lush rainforests. Ethereal silverswords, bird-pollinated geraniums, Seussian na'ena'e and mintless mints are a few of the amazing plants that evolved in the unique and diverse environment on Haleakala.
