Pharus glaber (Pharus Grass) A very interesting and attractive grass that forms a dense clump of foliage 18-24 inches tall and spreading slowly by rhizomes with wide mid green broad 4 to 5 inch long by 2 inches wide glabrous leaves that look more like a Ruscus in the lily family or even a ginger than it does a grass. Above the foliage forms an airy inflorescence followed by unusual black seed heads that have hooked hairs that attach themselves firmly to fur (and clothing), presumably as a strategy for dispersion. We are not sure if this plant will survive in southern California gardens with our cool moist winters but it certainly would be worth a try as it is quite unique and certainly would be an interesting conservatory plant. Pharus glaber was once native to a wide range in the sandy hammocks of central Florida but only two recently discovered natural populations are known to still exist in the United States. Prior to these finds it had been long thought to be extinct in Florida, though the species can also be found growing in other locations in the new world tropics. Not only are the leaves wider than a typical grass but they are held upside down because of a twisted petiole so the hairs typically found on the upper surface of a grass are on the lower surface with the upper surface smooth and shiny. This is the only genus in the grass family to have this characteristic and with a couple other genera are considered to be in their own subfamily, the Pharoideae, which is thought to have broken away early in the evolution of the grass. It was described by the German botanist Karl S. Kunth in in Nova Genera et Species Plantarum in 1816 and is sometimes listed as a synonym to Pharus lappulaceus that was described in 1818 by the French naturalist Jean Baptiste Lamarck (1744 –1829) in his Flore des Antilles. The name for the genus comes from the Greek word 'pharos' meaning "mantle", "a piece of cloth" or "cloak", possibly in reference to the broad leaves and the specific epithet is the Latin word that means "hairless", "smooth" or "bald" referring to the smooth upper surface of the leaves. It is sometimes also commonly called Creeping Leafstalkgrass. Our plants were grown from seed that had stuck to clothing worn by Randy Baldwin and John Greenlee when photographing a stand of this plant in September 2015 at Bok Tower Gardens in Lake Wales Florida. The accompanying images were taken at this time.
Information displayed on this page about Pharus glaber is based on our research conducted about this plant in our nursery library as well as from information provided by reliable online resources. We also include our own observations made about it as it has grown in the nursery gardens and other gardens visited, as well how the crops of this plant performed in the containers in our nursery field. We will also include comments received from others and welcome hearing from anyone who has information about this plant, particularly if it includes cultural information aiding others to better grow it.
