Sporobolus wrightii (Giant Sacaton) - A tall warm season semi-evergreen native American perennial bunchgrass with gray-green leaves to 4-6 feet tall by as wide topped by attractive branched flowering stems up to 5-6 feet tall which take on a nice golden color in winter. Plant in full to part sun in most any soil type, including alkaline ones, and irrigate infrequently to not at all but looks best and grows to its full height with an occasional watering. It is evergreen in our climate and cold tolerant well below 0° F and useful in gardens down to USDA Zone 5. To keep it neat looking we cut it back to a 1 foot tall clump in early spring. This beautiful grass has performed very well in our test gardens for over 15 years in non-irrigated and occasionally irrigated areas. Its inflorescences can be cut and brought inside for fresh and dried arrangements. It is a great replacement for other non-native, water loving grasses like maiden grass, Miscanthus sinensis and pampas grass, Cortaderia selloana - one of Randy's favorite larger grasses! Giant Sacaton is native to sandy open ground, rocky slopes, and moist clay flats, floodplains, and dry lakes from 2,000 to 7,000 feet in arid eastern California (near Parker) east to Texas and south to northern and central Mexico. Once a dominant species in its native habitat the range of this plant has suffered from habitat loss to agriculture and to grazing. The name for the genus comes from thje Greek words 'spora' meaning "seed" and 'ballein' meaning "to throw" alluding to the free seed and the manner of its release. The specific epithet honors American botanist Charles (Carlos) Wright (1811-1885) who collected widely in Texas. This species was first described in 1882 by British botanist William Munro and American botanist Frank Lamson Scribner in the Bulletin of the Torrey Botanical Club (9: 103) from a specimen collected the year prior from near Pantano, Arizona by the American botanist Cyrus G. Pringle. It is most commonly called Sacaton or Giant Sacaton but other common names include Big Sacaton and Wright's Dropseed. The common name "sacaton" comes from the American Spanish words zacatón and zacate that was derived from the Aztec Nahuatl word zacatl, meaning "a coarse grass". With encouragement from our friend John Greenlee (AKA "The Grassman"), we started growing this beautiful grass in 2004. In 2015 we submitted this plant for trialing in the UC Davis Irrigation Trials and it performed admirably at all irrigation levels but best at the lowest (20% ETo).
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 Sporobolus wrightii. |
