Silverswords may be gone with the wind. Silversword plants of Hawai'i - known by their Hawai'ian name 'ahinahina which translates to very grey - are unique to the Maui's Haleakala volcano summit area and to the Mauna Kea and Mauna Loa volcanoes on the Big Island. Each volcanic mountain has its own unique type of silversword. Source 6f.
