Chasmanthium latifolium - River Oats
$19.99
"Inland sea oats is a rhizomatous clump forming
perennial with characteristic drooping panicles. The
plant can reach four feet in height, but is most often
shorter. The leaf blades are broadly lanceolate (up to
one inch wide at base) giving it the common name
broad-leafed Chasmanthium. Seed heads are borne
in open panicles up to 10 inches long. The drooping
panicles are initially green turning straw colored as
seed ripen. Various shades of red sometimes occur
as the fruiting spikelets mature." (Neill, USDA)
Chasmanthium Latifolium Botany By Dr. John Hilty
Cultivation:
"The preference is partial sun, moist conditions, and a loamy or rocky soil. Plants tend to be smaller in areas that are drier and less fertile." (Hilty)
Faunal Associations:
"The flowers attract few insects because they are wind-pollinated. The caterpillars of the butterfly Enodia anthedon (Northern Pearly Eye) feed on the foliage of Inland Oats, as do the caterpillars of several Amblyscirtes spp. (Roadside Skippers), including Amblyscirtes vialis (Common Roadside Skipper), Amblyscirtes linda (Linda's Roadside Skipper), and Amblyscirtes belli (Bell's Roadside Skipper); see Bouseman & Sternburg (2001) and Bouseman et al. (2006). The latter two skippers are restricted to southern Illinois and neighboring areas, where their preferred food plant, Inland Oats, is more common. The larvae of a moth, Elachista brachyelytrifoliella mine the leaves of Inland Oats and other woodland grasses (Microleps website)." (Hilty)
