Description
Sorghastrum nutans is a monoecious perennial graminoid.[2] It is a bunching sod-forming grass with broad blue-green blades and soft plume-like golden-brown seed heads. This species can reach heights of 3-8 ft (0.91-2.44 m).[3]
Distribution
This species can be found in 42 of the 48 lower United States, from Arizona, northward through Utah, Wyoming, and Montana, and all states eastward. It also occurs in parts of Quebec, Ontario, Manitoba, and Saskatchewan provinces of Canada and in Mexico.[1][2]
Ecology
Habitat
It is one of the dominant grasses of tall-grass prairies but can be found in xeric and mesic woodlands and forests, along powerline right-of-ways and roadbanks, and in open habitats and forested landscapes.[1]
Phenology
Flowering occurs from late August through October.[1] A report of flowering in November also exists.[4]
Fire ecology
Frequencies in a non-burned site (NB66) had frequencies of 45 in 1966 and 75 in 2013.[5]
Use by animals
This species provides nesting material and structure for native bees to build their nests. Caterpillars, including those of the pepper and salt skipper (Amblyscirtes hegon) use it for food.[3]
Conservation and Management
Cultivation and restoration
Seeds collected in the fall can be propagated by sowing unstratified seeds in the fall or stratified seeds in the spring. Seeds require dry stratification.[3]
