Uses
Livestock readily graze purple lovegrass in the spring and early summer. On heavily grazed areas, deer dig up and eat the basal part of the stem during the winter.
Status
Please consult the PLANTS Web site and your State Department of Natural Resources for this plant’s current status, such as, state noxious status and wetland indicator values, , Use soil moisture sensors to measure the soil moisture of Poa spectabilis Pursh.
Description
Grass Family (Poaceae). Purple lovegrass is a native, warm-season, perennial bunch grass. The height is between 1 and 3 feet. The leaf blade is 8 to 18 inches long; densely hairy; stiffly ascending when young; tapers to fine point. The leaf sheath is longer than internodes; covered with long, gray hair. The ligule is hairy. The seedhead is open panicle 1 to 2 feet long and about as wide, bright purple until maturity; tuft of hair in axial of seed stalks, spikelets 6- to 12-flowered. Distribution: For current distribution, please consult the Plant Profile page for this species on the PLANTS Web site.
Management
This grass adds variety to livestock diet but is seldom abundant enough to be a key management species. It makes maximum production when no more than 50 percent of current year's growth by weight is grazed off. A summer grazing deferment of at least 90 days improves plant vigor. This grass increases under controlled annual burning.
Establishment
Growth starts in the early spring and continues into the fall. Purple lovegrass grows in colonies. It never makes up a large percentage of plant composition. The seedheads are weak, break off easily, and tumble in the wind. Some plants produce short, slender rhizomes. It is primarily adapted to medium- and coarse-textured soils.
