Where does succulent come from?
Argyroxiphium sandwicense ssp. sandwicense grow only at the top of the Mauna Kea volkano on Hawaii and has an extremely restricted range. The species may have been abundant on all slopes of Mauna Kea in prehistoric times. In 1991, the total population was estimated at about 495 individuals, of which only about 38 were naturally occurring (i.e., unplanted)
Altitude range: In origin the species between 2600 and 3800 meters elevation.
What succulent looks like?
The Mauna Kea silversword (Argyroxiphium sandwicense DC.) is a large rosette shrubs usually single-stemmed and rarely branched and is an impressive sight framed by the lava background of its volcanic habitat. This plant has a dense, broad crown of long, narrow, extremely shiny, silvery leaves forming a spherical or dome shaped structure. A single-stemmed individual lives for a number of years (5–50), produces a terminal inflorescence, then dies (monocarpic). When in flower the plant may be 3 meters tall and 75 cm wide.
How to grow succulent?
The plant lives for many years until it flowers; estimates of its life span range from 5–15 years to 40 or more years. Flowering occurs once in the dry season (June-november), with annual number of flowering plants varying dramatically from year to year. Plants with multiple rosettes produce one inflorescence for each rosette; flowering may occur over several years before all rosettes are exhausted.
