Ratibida columnifera (Nutt.) Woot.
(especially aspera and spicata), Monarda fistulosa,
Ratibida pinnata, Physostegia angustifolia, Silphium spp.
Those species that were seeded frequently, yet present infrequently ("ineffectively seeded") includes a mixture of eight native grasses and forbs: Andropogon scoparius, Achillea millefolium, Agropyron riparium, Agropyron caninum,
Ratibida columnifera, Bouteloua graeilis, Sporobulus eryptandrus, and Festuca ovina.
Prairie Coneflower
Ratibida columnifera lives 3-4 years and is a bushy 30-60 cm plant (12"-24").
Common grasses present in the study area were western wheatgrass (Agropyron smithii), blue grama (Bouteloua gracilis), side-oats grama (Bouteloua curtipendula), buffalo grass (Buchloe dactyloides), and Canada blue-grass (Poa compressa), interspersed with the common herbaceous perennials aster (Virgilus falcatus), snakeweed (Gutierrezia sarothrae), blazing star (Liatrus punctata), prairie cone-flower (
Ratibida co1umnifera), orange arnica (Arnica fulgens), and a sedge species (Carex pennsylvanica).
Forbs included black-eyed Susan (Rudbeckia hirta), lanceleaved coreopsis (Coreopsis lanceolata), purple coneflower (Echinacea purpurea), perennial lupine (Lupinus perennis), and gray-headed coneflower (
Ratibida pinnata).

Equisetum laevigatum, Hesperostipa comata, and Nessella viridula were the tallest species found in nongrazed plots while Carex stenophylla, Descurainia pinnata, and
Ratibida columnifera were the tallest species in grazed plots.
Among the most widespread and locally abundant species are Schizachyrium scoparium (except in Georgia), Sorghastrum nutans, Panicum virgatum and
Ratibida pinnata.
