'Alamo' Switchgrass
Short Description: 'Alamo', a lowland switchgrass, is a warm-season perennial bunchgrass native to the United States. 'Alamo' is best adapted to the Southern one-half of the U.S. and is used for hay, pasture, soil conservation, wildlife cover, and in recent years, the biofuel industry.
Description: 'Alamo' was originally collected in far south-central Texas on the banks of the Frio River near George West. The Plant Materials Center near Knox City, Texas selected and released 'Alamo' as an improved variety based on superior forage yield, seed production, and improved seedling vigor. In contrast to 'Kanlow', 'Alamo' is primarily adapted to regions south of I-70 which intersects Kansas east to west. 'Alamo' performs best in areas of 25 inches of annual precipitation or when planted in low lying areas in arid climates. 'Alamo' matures approximately 2 weeks later than 'Kanlow'. 'Alamo', with good moisture and soil fertility, can reach heights up to 10 feet and produce in excess in of 7 tons of biomass annually. 'Alamo' performs well on a wide range of soils from clay to very fine sand. Recommended seeding rates range from 4 to 6 Pure Live Seed pounds per acre.
