Kalm’s Brome
Cool-season perennial bunchgrass growing 2-4 feet tall. Distinguished by soft, hairy (pubescent) foliage that gives it a distinctive texture. Forms neat clumps through limited tillering. Produces open, drooping seed heads in early summer. Native to northern prairies and adapted to various moisture conditions. Well-behaved in garden settings and provides good textural diversity in prairie plantings.
