Gardens
Chasmanthium latifolium, northern sea oats

It is used in landscaping in North America, where it is noted as a relatively rare native grass that thrives in partial shade; the plant is recommended for USDA hardiness zones 3–9 in acidic sands, loams, and clays.[5][6]


Ecology

It is a larval host plant for the Northern Pearly-Eye, and its seeds are food for birds and mammals.[7] It is also eaten by the caterpillars of the pepper and salt skipper, Bell's roadside skipper, and bronzed roadside skipper butterflies.[8]
