Sisyrinchium palmifolium (Palm-leaf Yellow-Eyed Grass) - A grass-like evergreen perennial with blades of narrow 1/4 inch wide iris-like blue-green leaves making a dense 2 feet tall clump In later spring into summer the foliage is topped by an open branched winged inflorescence to 30 inches tall of many 1/2 inch wide bright star-like yellow flowers that rise above the foliage. The flowers open fully in the late afternoon and are a showy display through the summer months and often into late fall. Plant in full to part sun in a well-drained soil and irrigate occasionally to regularly. Hardy to 0 ░F and useful in USDA zones 7 and above. A great long flowering and cheery plant in the mixed meadow or in the perennial border. Sisyrinchium palmifolium is a variable species and one of the largest plants in the genus. It grows throughout much of South America, from northern Argentina, Bolivia, Brazil, Paraguay, Peru and Uruguay and has long been in cultivation after first being described by Linnaeus in 1767 to be included in his Mantissa Plantarum Altera in 1771. We first received this plant from the meadowmaster and grassman, John Greenlee, as Sisyrinchium macrocephalum, which is now considered to be one of the many synonyms for S. palmifolium ssp. palmifolium. Other synonyms include Bermudiana palmifolia, Eleutherine palmifolia, Glumosia palmifolia, Marica palmifolia, Moraea palmifolia and Paneguia palmifolia. Also confusing in the botanical records is that the name has also been used for plants later identified or reclassified as Eleutherine bulbosa (S. palmifolium Cav.) and Tigridia Pavonia (S. palmifolium SessÚ & Moc.). Another common name for it is Bird-Of-Paradise Sisyrinchium. 

This information about Sisyrinchium palmifolium displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
