Narrative
Potter County Germplasm is a perennial, warm-season, native bunchgrass. Spike dropseed occurs from western Texas up through Colorado and across through southeastern California and down across Sonora, Mexico. Plants are in small clumps usually 40-115 cm tall with a densely contracted and spike-like panicle. Panicle may be 15-50 cm long and 0.5-0.7 cm wide. Leaf sheaths are rounded glabrous on back, usually with long white hairs on the collar. Leaf blades are 4-35 mm long, flat or becoming involute, 3-8 mm wide and tapering toward the tip. Potter County Germplasm may be used in pure stands or as a component in seed mixtures for range seeding and conservation reserve plantings. Spike dropseed reseeds itself readily on ranges following overgrazing or drought. It may be used for stabilizing sandy soils that have high erosion potential. Its forage value is fairly palatable to all livestock. Wildlife can utilize the plants for food and ground nesting cover.
