Stipa gigantea (Giant Feather Grass) A densely mounding evergreen grass to almost 2 feet tall with narrow arching gray-green foliage. In spring to early summer the numerous well-spaced erect flower spikes rise another 4 feet or more above the foliage, terminating in 10 inch long panicles of long-awned purplish flowers that ripen to a wheat color and all the while shimmer and rustle in even the lightest breeze. Plant in full sun in well-drained soils with regular garden watering at first but requires little irrigation once established. Hardy to at least 0 F and useful in USDA zones 5 to 10. Great in a mass planting or as a single accent plant with plants in full flower a spectacular sight, particularly when back lit by the rising or setting sun and flowers - flowers remain attractive left on the plant well into fall and are good in dried arrangements. Occasionally seeds about in the dry garden but does not seem to be too pesky and unwanted seedlings are easy to remove when young. This plant is native to the south-western Europe and northern Africa from southern Spain and Portugal and northern Morocco, where it grows on stony and sandy soils. The name for the genus comes from the Greek word 'stupe' meaning "tow" and 'stuppeion' meaning "fiber" in reference the use of fibers of Esparto Grass, Stipa tenacissima to make rope and the specific epithet appropriately describes the tall flowering stems. Other common names include Giant Needle Grass, Golden Oat, Spanish Oats and Giant Oats. This plant received the Royal Horticultural Society's prestigious Award of Garden Merit in 1993. We have grown this stunning plant since 1992.  The information on this page is based on the research that we have conducted about this plant in the San Marcos Growers library, from what we have found on reliable online sources, as well as from observations made of our crops of this plant growing in the nursery and of plants growing in the nursery's garden and those in other gardens where we may have observed it. We also have incorporated comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing Stipa gigantea.
