Sunflowers and mealy cup sage will appear in the summer, and black-eyed Susans and gayfeathers will bloom in the fall, Pfeil said.
Domesticated versions of prairie flowers like Kansas gayfeather ( Liatris spicata ) and meadowsweet ( Filipendula purpurea ) will grow and bloom reliably without the gardener standing over them with a watering can.
Pair it up with the blue spires of Veronica " Sunny Border Blue " and Lobelia siphilitica ( blue lobelia ) or the purple spikes of Liatrus spicata ( Gayfeather ), and your garden will turn heads.
In native prairies, switchgrass is historically found in association with several other important native tallgrass prairie plants, such as big bluestem, indiangrass, little bluestem, sideoats grama, eastern gamagrass, and various forbs ( sunflowers, gayfeather, prairie clover, and prairie coneflower ).
Arboretum plants include woodland wildflowers such as shinleaf, rattlesnake-plantain, blue-bead lily, and pink lady's slipper; prairie vegetation such as silky prairie clover, birdfoot violet, blue-eyed grass, gayfeather, and pasque flower; and grasses such as big bluestem, kalm's brome, muly-grass, porcupine grass, and June grass.
