Where does succulent come from?
Argyroxiphium sandwicense subsp. macrocephalum is found on the island of Maui, United States (Hawaiian Is.) in an area of occurrence about 1,000 ha. It grows at elevations of 2100–3,000 metres in the alpine deserts on the dormant Haleakal? volcano (on the summit depression, the rim summits, and surrounding slopes) in Haleakal National Park. It also grows in dry to moist subalpine shrublands.
What succulent looks like?
The Haleakala silversword, Argyroxiphium sandwicense subsp. macrocephalum, is a single-stemmed, or rarely branched, spherical rosette shrubs with numerous sword-like succulent leaves appearing to have been dipped in silver or mercury. At senescence, which often occurs when the plant reaches a diameter of approximately 0.5 metres, the plants produces a tall terminal inflorescence of maroon-purple ray flowers which resemble the sunflower in just a few weeks. It can flower in as little as three years in cultivation, but normally requires 15-50 or more years in natural habitat. Plants with multiple rosettes produce one inflorescence for each rosette; flowering may occur over several years before all rosettes are exhausted, then dies. Such is the life of a monocarpic plant. The silversword in general is referred to as `Ahinahina in Hawaiian (literally, “very gray”).
