Ampelodesmos mauritanicus a large clumping evergreen bunchgrass to 3 feet tall by as wide with tough leathery green leaves and in summer appear the arching stems to 6 feet high holding 1- to 2-foot-long flower panicles with small white to purple flowers that nod to one side
Plant in full sun in a well-drained soil and irrigate occasionally to keep evergreen. It is cold hardy to 10-15°F and useful in USDA Zone 8 and above. It tolerates dry summer conditions but though fire tolerant, its dry leaves are prone to burn so irrigation in summer to keep it green is advisable in fire prone areas. It has tolerance to wind and salty conditions so good in coastal gardens. While it has been noted as non-invasive in grass collections in English gardens, it has sparingly naturalized in Napa and Sonoma counties in California. This is a very pretty grass with its tall flower stems that move even in gentle breezes. Careful placement away from paths in the garden is important as the leave edges are sharp and can cut one's skin.
Native to drier regions of the Mediterranean coast in southern Europe from Spain to Greece and Northern Africa where its leaves and culms have long been used for mats, vine ties, brooms, baskets, and thatching. The genus name comes from the Greek words 'ampelos' meaning a "vine" and 'desmos' meaning "bond" or "to bind" in reference to this plant's leaves being used to make string to tie up grapevines. The specific epithet is a reference to this plant growing in Mauritania in northwest Africa. The Jepson Manual notes the current name of this taxon to be Stipa mauritanica (Poir.) Columbus & J.P.Sm. based on molecular phylogenetic studies and the circumscription of Stipa that was expanded to include all Stipeae (native and non-native) growing in California. This from an article authored by J. Travis Columbus and James P. Smith Jr. titled "Nomenclatural Changes for Some Grasses in California and the Muhlenbergia Clade (Poaceae)" in the 2010 issue of Aliso: A Journal of Systematic and Floristic Botany (V.28 N.1 pg65-67). The Royal Botanic Garden Kew Database however continues to use Ampelodesmos mauritanicus as the current name for this plant. It also in the past has been included in the genus Arundo. It has the common names Stramma, Mauritania or Mauritanian Grass, Rope Grass, and Diss Grass.
