Sabal rosei

Sabal rosei, the Llano Palm, is a handsome fan palm from the Pacific side of Mexico, ranging through the states of Sinaloa and Jalisco, where the palm covers the coastal plains, the llanos, by the hundred thousand. Thick, blue-green, leathery fan leaves give the plant a bold, sculptural quality, and the slim, straight trunk is either patterned with a neat spiral of old leaf bases or swept clean to reveal the ring-like scars beneath. For all that abundance in the wild, Sabal rosei is almost unknown in cultivation, which makes the palm a real find for the collector. Our own plants were grown from seed given to us by Joe Le Vert of Aquinas High School, and we are glad to have it: the species is easy from seed and, unusually for a Sabal, a fast and reliable grower, tolerating both flooding and drought while favoring the dry, open ground of the native llanos. Small yellow flowers, an uncommon color in a genus mostly given to whitish bloom, are followed by black berries. Despite the tropical Mexican home, the Llano Palm is cold hardy to around twenty degrees Fahrenheit, into USDA Zone 8, opening the door to gardeners well outside the tropics. Like the other fan palms of Mexico, the species belongs to a group whose leaves have long been cut for thatch and fiber, so a working history sits behind the ornamental one. In the garden Sabal rosei makes a striking specimen for a hot, sunny, well-drained spot, the thick blue-green fans and clean trunk reading against sky, stone, or a plain wall. Drought tolerant once established and unbothered by heat, the palm pairs naturally with agaves, yuccas, and other sun-and-drought lovers in a gravel or xeric planting. Site in full sun, give room for the crown, and grow a genuinely rare palm with room to reward a collector's patience.
