Northern Sea Oats has showy oat-like seedheads in August over green foliage. An excellent choice for planting under the light shade of tall trees and especially showy when planted in mass. Great for dried grass arrangements. Chasmanthium latifolium is a larval host to caterpillars of Northern Pearly Eye Butterfly and several species of Skippers. In addition, birds and woodland animals love the seeds especially in winter. It seeds itself readily so site correctly or deadhead seed pods before they ripen.
